Rocks become ice when they get cold, which can later melt and wash away.

Answer 1

The correct response is:

Rocks expand and contract when they are heated and cooled which cause them to break.

This process is known as thermal expansion and contraction, and it can lead to the physical weathering of rocks.

mantle

Answer 3

The correct response is:

crust

Physical weathering primarily occurs in the Earth's crust, where rocks are exposed to various environmental factors such as temperature changes, water, and wind.

Answer 4

Which is the last stage of physical weathering in rocks? (1 point)
Responses

sand
sand

pebble
pebble

boulder
boulder

rock

Answer 5

The correct response is:

sand

In the process of physical weathering, rocks break down into smaller and smaller pieces, ultimately resulting in sand as one of the final stages of weathering.

Answer 6

What must be present on a rock that undergoes frost wedging?(1 point)
Responses

holes around it
holes around it

a crack
a crack

sharp edges

round shape

Answer 7

The correct response is:

a crack

Frost wedging occurs when water enters cracks in the rock, freezes, expands, and then thaws, causing the crack to widen and eventually break the rock apart.
