What is weathering?
100
mechanical weathering that occurs when water freezes in cracks of rocks
What is ice wedging?
100
build up features on Earth's surface
What are constructive forces?
100
laying down of sediments or setting down of eroded materials
What is deposition?
100

mixture of weathered rock, rock fragments, decayed organic matter, water, and air

What is soil?

200

rocks are broken into smaller piece by physical processes

What is mechanical weathering?

200
weathering that occurs when rock is ground away by friction or impact
What is abrasion?
200

tear down features on Earth's surface

What are destructive forces?

200
this is an example of a depositional environment
What are swamps, deltas, beaches, or the ocean floor?
200
remains of something that was once alive
What is organic matter?
300
materials that are part of a rock change into new materials
What is chemical weathering?
300
create holes in soil where water enters and causes weathering
What are animals?
300

this is an agent of weathering

What is wind, water, or ice?

300
this landform can be formed from erosion
What are hoodoos, mountains, seacliffs, or sea caves?
300
small holes and spaces in rock layers
What are pores?
400
combines the element oxygen with other elements or molecules
What is oxidation?
400

water dissolves minerals in rock

What is chemical weathering?

400
removal of weathered material from one place to another
What is erosion?
400

this is a landform created by deposition

400
process of changing once living material into dark colored organic matter
What is decomposition?
500
the rate of weathering depends on this
What is type of rock or environment?
500
a river flowing
What is abrasion?
500
this is an agent of erosion
