Weathering
What is weathering?
The breaking down of Earth's surface into smaller pieces.
What is erosion?
After the pieces are broken down through weathering, they are moved from one place to another.
What is a fossil?
Any remains, traces, or imprints of animal or plant life preserved in Earth's crust.
What is another name for the peak of a mountain?
Summit.
Fast running water causes rocks to hit one another breaking them into smaller rocks.
Physical Weathering.
Name 2 types of physical weathering.
1. Abrasion (Hitting together)
2. Freezing
3. Wind
4. Water
5. Landslides
What is deposition?
After pieces of Earth are broken down and carried through erosion, they are put somewhere else.
True or False: All fossils are of dinosaurs.
False
What is elevation?
How high above sea level a landform is.
The soil from a hillside is washed away by rain.
Erosion.
How can rain cause chemical weathering?
When it is acid rain.

1. Rain
2. Landslide
3. Wind
4. Gravity
What is a mold fossil?
A space left by an animal, plant, shell, etc. in the sedimentary rock that fills with minerals
What is a topographic map?
A map that shows changes in elevation of a landform, such as a mountain.
Waves dropping sand on a beach.
Deposition
True or False: Color change is an example of physical weathering.
False, if a color has changed, then chemical weathering has taken place.
Name 2 ways that rocks, soil, and sediment can be deposited?
1. Wind
2. Ice

What is a cast fossil?
A fossil that is created by the minerals in a mold.
What mountain have we been studying?

Erosion
Give 1 example of chemical weathering that we can find in our daily lives.
1. Statue of Liberty
2. Rusting of metal
True or False: Deposition can change our Earth's landscape.
True.
How can scientists determine the age of fossils?
The layer of sediment in which a fossil is found can help determine its age.
How did Mount Shasta form?
Volcanic eruptions caused the Earth to move together and rise upward.
Layers of sediment forming at the bottom of the ocean.
Deposition.
