Instructions: Answer all questions to get your test result.
1) What is deposition?
A
The gradual wearing down of a geological formation due to its physical or chemical changes to the surface of rocks

When sediment created by weathering and moved by erosion settles in a different location due to gravity
D
The nonliving components of an ecosystem, such as soil and sunlight
