Define It!
The process by which small pieces of rock and soil are moved.
What is:
EROSION
What are the different types of weathering?
physical and chemical
Can erosion happen if the sediment doesn't move?
No
Do weathering, erosion, and deposition work together?
YES!
How does the action of wind and water affect rock?
by gradually breaking down the rock into smaller pieces
When the earth's surface is broken down into smaller pieces.
What is:
WEATHERING
What are the 4 things that can cause weathering?
What are:
a. Wind
b. Water
c. Ice
d. Gravity
True or false:
Erosion is moving
What is:
True
What are the different ways of deposition?
What are:
a. Wind
b. Rain/Water
c. Ice
What are the main natural forces that change the landscape of earth?
water, wind and ice
When the small pieces are deposited in a new location.
What is:
DEPOSITION
The process of weathering by scraping or rubbing of two physical objects with friction
abrasion
Can erosion happen before weathering?
No, weathering must occur first, then the broken pieces are carried away.
Is deposition a slow-moving or fast-moving change?
What is:
Slow Moving
What causes sinkholes and caves to form?
chemical weathering, dissolving of soft rock
Small, solid pieces of material that come from rocks or living things
What is:
Sediment
Give a real life example of both types of weathering
Up to Mr. G
Which process best demonstrates erosion?
A. A boulder expands during a forest fire.
B. A seedling sprouts inside a sidewalk seam.
C. A statue's features are worn away by acid rain.
D. A crack in a brick grows larger when water freezes inside.
What is:
C
What pulls pieces of rock downhill to create a landslide?
What is:
Gravity
Sand Key is a barrier island located along the coast of Florida. Which process most likely caused Sand Key to form?
deposition of sand over time
Water that moves across the land surface and into streams and rivers
What is:
Runnoff
Name two landforms created by weathering
canyons, cliffs, sinkholes, caves, arches and valleys
Erosion can be caused by what forces?
What is:
1. Wind
2. Ice
3. Water
What is the difference between Erosion and Deposition?
Erosion is the process by which small pieces of rock and soil are moved.
Deposition is When the small pieces are deposited in a new location.
What is the difference between weathering and erosion?
Weathering is the process of breaking parts of the earth down Erosion Gets rid of the elements of the earth that have moved and are left behind.
