The oxidation of minerals that contain iron.

Repeated freezing and thawing of water that cracks rocks.

Acids from plant roots which break up rocks

Formation of potholes in streets during severe winters

Lifted sections of sidewalk along tree lined streets.

A large rock falling from a cliff and then breaking.

Feldspar mixed with water, producing clay minerals.

Rocks that have been carried by streams and have become smaller and more round.

Tree roots cracking the concrete foundation of a house.

The diagram above shows what happens to a rock within a stream’s erosional-depositional system as time passes. Which process of change is best represented by the sequence shown in the diagram?

In the cartoon above, the mountain climber’s remarks show that he is aware of which pair of Earth processes?

The diagram above shows the stump of a tree whose root grew into a small crack in bedrock and split the rock apart. The action of the root splitting the bedrock is an example of

The diagram above shows four magnified block-shaped sandstone samples labeled A, B, C, and D. Earth sandstone sample contains quartz grains of different shapes and sizes. The quartz grains are held together by hematite cement. In which sample did the quartz grains undergo the most abrasion during the erosional transport?

The diagram above shows a process of weathering called frost wedging. Frost wedging breaks rocks because as water freezes it increases in

The diagram above represents a naturally occurring geologic process. Which process is best illustrated by the diagram?

Rock samples brought back from the Moon show absolutely no evidence of chemical weathering. This is most likely due to
