Changing Earth's Surface Flashcards
sediment is…
material moved my erosion is sediment. Sediment may consist of pieces of rock or soil or the remains of the plant and animals.
Erosion is…
the process by which natural forces move weathered rock and soil from one place to another.
deposition is…
occurs where agent of erosion, deposit, or lay down, sediment.
gravity is…
Gravity pulls everything down to the center of the Earth. Gravity is the force that move rocks and other materials downhill. It also causes mass movement.
mass movement is…
Any one of several process that move sediment downhill. The different types are slump, creep, landslides, and mudflows.
Landslides is…
The most destructive type of mass movement. the speed one second fast and the slope is steep.
mudflows are…
they occur in a usually hot place after it heavily rained. They’re rapid and they have gentle/ steep slope.
creep is…
often results from freezing and thawing of water from cracked layers of the rock beneath the soil. It has fast speed and steep slope.
slump is…
it has very slow speed and gentle/steep slope. Occurs when water soaks the bottom of soil that is Rich Clay.
