​Students will describe and give examples of processess that change Earth's surface such as erosion and deposition.

Students will describe how mass movement of rock and soil on Earth's changes that surface.

Students will describe how wind contributes to erosion and deposition and causing changes to Earth's surface.

​Objectives

Multiple Choice

What is erosion?

• A solid material that is moved and deposited in a new location.

• When sediments of Earth's surface are moved from one place to another.

• The movement of masses of bodies of mud, bedrock, soil, and rock debris, which commonly happen along steep-sided hills and mountains because of the gravitational pull.

• Erosion by wind of loose material from flat areas of dry, uncemented sediments such as those occurring in deserts, dry lake beds, floodplains, and glacial outwash plains.
