Unit 4: Factors Impacting Earth’s Systems Test Review
1. Match the following vocabulary with their definition.
A.
___ Weathering
B.
___ Erosion
___ Deposition
C.
___ Mechanical/Physical Weathering
D.
___ Chemical Weathering
E.
movement of sediments
weathering that changes the composition of
the rock, creates a new substance like rusting
breaking of rock into smaller sediments
dropping off of sediments in a new location
weathering that keeps the same composition,
only changes size
2. Classify the following as mechanical weathering (MW), chemical weathering (CW), erosion (E), or
deposition (D).

Abrasion ____
Enchanted Rock ___
Water ____
River Delta ____
Gravity ____
Oxidation ____
River Canyon ____
