GEOLOGIST'S NOTEBOOK WHY LAND GOES UP AND DOWN Grades 2-6 Viewing Time: 10.5 minutes with a five-question Video Quiz INTRODUCTION TO THE SERIES Why Land Goes Up and Down is part of the Geologist's Notebook, which is intended to help elementary students dig into a variety of important topics in geology and earth science. This six-part series of 10.5 minute programs uses 3-D animation and live-action footage to address uplifting and erosion, the rock cycle, soil formation, minerals and crystals, Earth's interior structure, natural resources, fossils, and landforms. A light-hearted touch often lightens the heavy "lode" of information which each show offers. INTRODUCTION TO THE PROGRAM Why Land Goes Up and Down is an excellent presentation of the forces behind making our planet's landscape. Land around us is rarely flat. As it stretches across mountains, valleys, canyons, plateaus, and other landforms, it goes up and down, down and up. This show looks at the two processes most responsible for carving our landscape: uplifting and erosion. It explains how tremendous heat from the center of Earth powers the building of mountains and plateaus by moving plates and pushing up bulges in the crust. Similarly, the show examines how the forces of erosion, especially moving water associated with gravity, work equally hard to reduce uplifts crust sediment, and flat land. The effect of glaciers is also touched upon. After watching this program, students will better understand why, in terms of land, what goes up must come down. 1 LINKS TO CURRICULUM STANDARD According to the National Science Education Standards: • Content Standard D (K-4): Changes in earth and sky The surface of the earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes. • CONTENT STANDARD F (K-4): Changes in environments Some environmental changes occur slowly, and others occur rapidly. Students should understand the different consequences of changing environments in small increments over long periods as compared with changing environments in large increments over short periods. • Content Standard D (5-8): Structure of the Earth System Landforms are the result of a combination of constructive and destructive forces. Constructive forces include crustal deformation, volcanic eruption, and deposition of sediment, while destructive forces include weathering and erosion. Lithospheric plates on the scales of continents and oceans constantly move at rates of centimeters per year in response to movements in the mantle. Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from these plate motions. SUMMARY OF PROGRAM Land is rarely flat. Landforms, such as mountains, valleys, and cliffs can be found around the world. Geologists explain that landforms are mainly results from two processes: uplifting and erosion. 2 Uplifting raises land. The energy that causes uplifting comes from heat in the middle of Earth, where temperatures are thousands of degrees hotter than Earth's surface. The crust is a thin shell of solid rock that protects us from this inner heat. The crust is divided into approximately twenty pieces, called plates. This heat moves from the center of Earth towards the crust. Sometimes the inner heat creates bulges in the crust. Bulges start with giant plumes, bubbles of extra hot heat rising from deep within Earth. Sometimes they push so hard against the plates, they create a bulge. An example of a plume that causes hotspots and geysers can be found below Yellowstone National Park, in North America. The park also sits on a plateau that was formed by the plume pushing up the surrounding countryside. Millions of years ago the plume burst through the crust, creating volcanoes. This inner heat also causes Earth's plates to slowly move in different directions. This is a slow process causing plates to move very little each year. We usually don't feel this unless it creates an earthquake. Some plates pull away from one another and others collide. Over millions of years, plate edges crinkle, twist, and break. This pushes up the land, creating mountains. Pieces that tilt down can make mountain valleys. Together hot plumes, volcanoes, and colliding plates have uplifted a large portion of the planet starting a long time ago and continuing in recent times. Erosion transports rocks and soil. Wind and water both cause erosion, but water is the main force. Water pushes pieces of rock and soil ranging in size. Water lubricates rock and soil so they slip down; water can also dissolve them. Billions of drops of water together have huge power! Gravity assists water in the process of erosion. Together they transport material downhill. Erosion works hardest at the highest, steepest areas with softened sur3 faces. Unequal erosion can produce interesting results, such as rock towers. Over time erosion flattens land. It transports material from high places and deposits it in low areas. For example, mountains erode downward and fill up valleys. Eventually ending up at the bottom of the ocean. Glaciers have also helped to shape land. Over 10,000 years ago, great sheets of ice moved from the poles. As they moved, they flattened the land they crossed in the process. They also left behind countless lakes, including the great lakes. Small glaciers still survive in many of the world's high mountains. In conclusion, landforms will change in the future because uplifting and erosion never stop working. Earth's inner heat will continue to rise to the surface and move the plates around, causing uplifting. Gravity and water will continue to erode land above sea level. What goes up must come down.

Resources should be made available to the students to find the location of different landforms. Landform plateau How is it formed? a plume pushing land up Where can it be found? Yellowstone National Park Blackline Master #6, Cloze Geologists say landforms result mostly from two processes. One is uplifting, which raises land. The second is erosion, a process that carries away land. The energy for uplifting starts as heat from the middle of Earth and reaches the crust. The heat creates bulges in the crust. These bulges start with giant bubbles of extra hot heat rising from deep within Earth, called plumes. Plumes push so hard against a plate they create a bulge. The inner heat also causes the plates to move. Some plates pull away and others collide. Pieces of land that tilt up create mountains. Pieces of land that tilt down can create mountain valleys. Erosion works with gravity to move rock or soil, transporting materials downhill. Erosion can form steep valleys or flatten land. Glaciers have also helped form the land on Earth. As it moved slowly more than 10,000 years ago, land was flattened and lakes were created. Landforms around us will change the future because erosion and uplifting are ongoing processes. It is an endless cycle, what goes up must come down. Blackline Master #7, Post-Test 1. Plates move from the heat rising from the inner core of Earth. This heat energy moves plates slowly. Plates can collide and pull away from one another. 2. flat land 13 3. True 4. Plate edges crinkle, twist, and break. Pieces of land that tilt up create mountains. Pieces that tilt down can create valleys. 5. moving rock or soil 6. both A and B 7. Erosion carries rock and soil downhill. Wind and water can cause erosion, but water is the main force. Water can carry away material, lubricate rock and soil so they slide, and dissolve rock and soil. Erosion can create steep valleys, interesting rock formations, and flattens land. 8. False 9. lakes 10. Answers will vary.

Strange rock shapes tower overhead. Steep cliffs challenge our footing. We call these hills, valleys, canyons, and other natural features of Earth's surface landforms. What causes the surface of Earth to be so varied, to have mountains, valleys, and so many other remarkable shapes? Geologists, scientists who study Earth from its soil to center, say landforms result mostly from just two processes. One is uplifting. Uplifting raises land. Mountains are uplifted. The second is erosion. Erosion carries land away. This canyon and this plain are both results of erosion. How do uplifting and erosion work? Uplifting All the bulldozers in the world would have trouble making just a single mountain range, but Earth has mountains and hills almost everywhere. Where does Earth get the energy to uplift mountain ranges? Energy for uplifting starts as heat in the middle of Earth, where temperatures reach thousands of degrees. Earth is hottest at its center and cools slightly towards the crust. The crust is a thin shell of solid rock that gives our planet a hard surface and protects us from its inner heat. Sometimes the inner heat creates bulges in the crust. A bulge starts with a giant bubble of extra hot heat rising from deep within Earth. The bubble, called a plume, may push hard enough against the plate to uplift part of it. One such plume lies below Yellowstone National Park. Heat seeping from it helps create the parks famous hotspots 17 and geysers. The park sits on a bulge called a plateau, or platform of raised land, that has been uplifted from the surrounding countryside by the plume. Millions of years ago the plume also burst through the crust, creating volcanoes that covered huge areas with thick layers of lava. The lava, which quickly hardened into rock, added even more height to the plateau. Rising internal heat not only causes bulges, it moves huge pieces of crust. Earth's crust is broken into about 20 pieces called plates. Heat currents slowly move the plates in various directions. We cannot feel the plates move because they travel so slowly, about half the length of a pencil per year. Some plates pull away from one another, others collide. Over millions of years colliding plate edges crinkle, twist and break just like fenders in a car wreck. While this goes on, earthquakes are common. Pieces of land that tilt up create mountains. Pieces that tilt down can make mountain valleys. Plates collide in several places around the world right now, including along the west coast of North America and in central Asia where the Himalayas push skyward. The Himalayas grow taller about an inch/2.5 centimeters per century. Together, hot plumes, volcanoes, and moving plates have uplifted a large portion of the planet in the recent or distant past. Erosion No matter how land gets uplifted, as soon as it rises, it gets attacked by the second major land shaping process, erosion. Erosion transports - or moves - rock and soil. 18 Most erosion results from three causes: wind, water, and ice. Wind erodes by picking up and carrying loose soil. Dust storms are wind erosion in progress. Wind blown sand also grinds even the hardest surfaces, such as rocks. Water is erosion's most active force. Water pushes pieces of rock and soil ranging in size from tiny specs of mud to huge boulders. Water also lubricates rock and soil so they simply slide down. Water even weathers, or breaks down, rocks to carry them away. A single drop of water is gentle, but billions of drops have huge power. Water is always helped by gravity. Together, water and gravity transport materials downhill, in the opposite direction of uplifting. Ice helps erosion in a couple of ways. First, it breaks rocks into smaller pieces that are easier to move. More importantly ice forms glaciers, which are huge sheets of moving ice. As recently as 10,000 years ago, glaciers several miles or kilometers thick reached far from the poles. They acted like immense bulldozers, scraping everything flat, and moving huge amounts soil and rock. The effects of these heavy sheets of ice are visible today. Huge areas still remain flat. In other places, stand hills called moraines that got left behind when glaciers dumped the soil and rocks they carried. Glaciers also created countless lakes, including the five Great Lakes. Small glaciers still survive in some of the world's coldest areas. At first, erosion may seem to make land rugged. Landforms we see here have been carved by erosion. 19 But over time, erosion flattens land. Erosion transports material from high places and deposits - or drops - it in low areas. Mountains erode down, valleys fill up. Eventually, if it were not for uplifting, erosion would level the Earth to a flat surface. Conclusion Landforms around us will change in the future because uplifting and erosion never stop working. The middle of Earth will send heat to the crust for billions of years more, and all the while the crust will fold, move and break. Gravity and water will continue to erode all land that is not flat. And the two forces of uplifting and erosion will work together to form an endless cycle, where what goes up must come down. Questions: True or False 1. Energy for uplifting starts as heat in the middle of Earth. 2. Colliding plates can uplift mountains. 3. Erosion transports rock and soil. 4. Water is the only cause of erosion. 5. Uplifting and erosion will take place in the world tomorrow. 20 1 Name ____________________ GEOLOGIST’S NOTEBOOK WHY LAND GOES UP AND DOWN Pre-Test/Anticipation Guide Directions: Circle the best answer to the following questions before viewing the program.

Once you have read it, fill in the blanks using the key vocabulary. Key vocabulary: bubbles, bulges, energy, flatten, geologists, gravity, heat, lakes, mountains, ongoing, processes, plates, plumes, uplifting, valleys. _________ say landforms result mostly from two ___________. One is ________, which raises land. The second is erosion, a process that carries away land. The __________ for uplifting starts as ________ from the middle of Earth reaches the crust. The heat creates __________ in the crust. These bulges start with giant __________ of extra hot heat rising from deep within Earth, called plumes. _________ push so hard against a plate they create a bulge. The inner heat also causes the ____________ to move. Some plates pull away and others collide. Pieces of land that tilt up create ___________. Pieces of land that tilt down can create mountain _________. Erosion works with __________ to move rock or soil, transporting materials downhill. Erosion can form steep valleys or ___________ land. Glaciers have also helped form the land on Earth. As it moved slowly more than 10,000 years ago, land was flattened and _________ were created. Landforms around us will change the future because erosion and uplifting are ___________ processes. It is an endless cycle, what goes up must come down. © 2003 Maslowski Wildlife Productions Published and Distributed by United Learning All rights to print materials cleared for classroom duplication and distribution. 7 Name ____________________ GEOLOGIST’S NOTEBOOK WHY LAND GOES UP AND DOWN Post-Test Directions: Answer the following questions with your best effort.

In this experiment you will build a real working volcano. After mixing just the right amount of ingredients together, add the final item to make your volcano spew red lava down the sides. 1. First you need to create the "salt dough." Mix the ingredients a large bowl. Work the ingredients with your hands until smooth and firm. Add more water to the mixture if needed. 2. Stand the soda bottle in the baking pan. Mold the salt dough around the bottle making sure you don't cover up the bottle mouth or drop any dough into the bottle. Take your time on this step and build your volcano with as much detail as you like. 3. Fill the bottle most of the way with warm water mixed with a little of the red food coloring. 4. Put six drops of the liquid detergent into the bottle. 5. Add two tablespoons of baking soda. 6. Slowly pour vinegar into the bottle and jump back quickly! Notice the red "lava" that flows out of your volcano. This happens because of the baking soda and vinegar mixture. Mixing baking soda and vinegar produces a chemical reaction in which carbon dioxide gas is created - the same gas that bubbles in a real volcano. The gas bubbles build in the bottle, forcing the liquid "lava" mixture from the bottle and down the sides of your volcano. © 2003 Maslowski Wildlife Productions Published and Distributed by United Learning All rights to print materials cleared for classroom duplication and distribution.
