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.

LINKS TO CURRICULUM STANDARD
According to the National Science Education Standards:
• Content Standard D (K-4): Changes in earth and sky
ŠThe 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
ŠSome 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
ŠLandforms 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.
ŠLithospheric 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.

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.

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.

SCRIPT OF NARRATION
Land around us is rarely flat. Valleys and hills roll out into
the distance. 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.

Landforms Cloze Activity
Directions: Read the paragraph once, before filling in the blanks with key vocabulary words.
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.

WHY LAND GOES UP AND DOWN
Make a Volcano
Materials:
salt dough: 6 cups flour, 2 cups salt, 4 tablespoons oil, 2 cups warm water
plastic soda bottle (one liter)
9" X 9" baking pan
red food coloring (a few drops)
liquid detergent (6 drops)
baking soda (2 tablespoons)
vinegar (2-8 ounces)
Directions: Now we're going to get a little messy. 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.
