What is weathering?

breaking rocks into pieces

100

What is erosion?

when rocks or sediment are carried somewhere

100

What is deposition?

when rocks or sediment are put down somewhere
100

What is a glacier?

layers of snow that build up and freeze into a giant block of ice

200

What is the C horizon of soil?

bedrock 

200

Which types of mass movement occurs rapidly when a single mass of soil and rock suddenly slip downhill?

slump

200

What is a rill?

A water filled grove in the soil. 

200

How do waves cause erosion?

by continually hitting cliffs they pick up sediment and carry it into the ocean
300

How does the A horizon of soil form?

dead leaves become humus which mixes with the B horizon
300

How are erosion and deposition alike?

Both change Earth's surface over time. 

300

Sediments get deposited in an alluvial fan because ___________. 

a stream deposits sediment at the bottom of a hill. 

300

Which is faster wave erosion or glacial erosion?

wave erosion

400

How does acid rain cause weathering?

by dissolving rock

400

Deposition by _________ causes sand _________ to form.

Deposition by wind causes sand dunes to form.

400

Which of the following processes causes sinkholes to form?

erosion of limestone by groundwater

400

Glaciers erode Earth's surface through the processes of ___________ and ___________. 

Glaciers erode Earth's surface through the processes  of abrasion and plucking. 

500

Mechanical weathering breaks some limestone into pieces. What effect would this have on chemical weathering of limestone?

Chemical weathering would occur at a faster rate.
500

A scientist observes that over several decades, fence posts placed in soil on a slope became tilted. Have erosion, deposition, or both occurred in this area? 

Both erosion and deposition by gravity occurred. Gravity causes creep, the very slow downhill mass movement of rock and soil. Creep happens very slowly and causes objects to tilt. 

500

What is the correct order of stream formation from raindrops to rivers?

raindrops, rills, gullies, streams, river, tributary

500

How does longshore drift affect Earth's surface?

Sediment moves down a beach with the current.
