Plates
What are the four layers of the Earth?
inner core, outer core, mantle, crust
True or False: A landform is made from humans and nature
FALSE
What is erosion?
The movement of sediment
What is weathering?
the breaking down or dissolving of rocks
What is an earthquake?
A strong, sudden shaking of Earth's crust.
What is the theory that explains the movement of plates?
plate tectonics
What type of landform is created after a volcano erupts?
A mountain
How is gravity a type of erosion? Explain
*answers may vary
Gravity is the force that pulls everything down, therefore, if there is a steep incline, gravity will pull pieces of sediment downwards.
What are the three types of weathering?
chemical, physical, biological
What is deposition?
When sediment lands somewhere new from erosion
What is a fault?
A crack in the Earth's crust
A landform with steep sides and a flat top
True or False: Glaciers are a type of water erosion
False: glaciers are ice erosion
What is biological weathering?
when animals or plants break down rock
A hole in the Earth filled with molten rock.
What is a convergent plate boundary?
When two plates slide together- often times one plate being pushed underneath the other.
How is a canyon formed?
By weathering and erosion- most often by wind and water.
Sand being blown at the beach is an example of what type of erosion?
wind erosion
What is abrasion? What type of weathering is it?
Abrasion is when rocks rub against each other causing them to break into smaller pieces. This is a type of physical weathering.
What is magma?
molten rock inside the earth.
What is a divergent boundary?
When two plates move away from each other.
What landform typically is farmland?
plains
Give an example of water erosion
*answers will vary
ex: river carries sediment
Does chemical weathering change the rock's composition?
Yes
What is the ring of fire?
Where most of the Earth's volcanos and earthquakes are located.
