What happens to a rock when it weathers?

It settles out of water that is carrying it.

It creates a valley.

It forms a delta.

It breaks into small pieces.

Acid rain causes

physical weathering.

chemical weathering.

both chemical and physical weathering.

neither chemical or physical weathering.

Freezing causes

physical weathering.

chemical weathering.

both chemical and physical weathering.

neither chemical or physical weathering.

Tree roots cause

physical weathering.

chemical weathering.

both chemical and physical weathering.

neither chemical or physical weathering.

Physical and chemical weathering both

change rocks into new materials.

dissolve rocks.

break rocks into smaller pieces.

require exposure to air.

Physical and chemical weathering differ because

only chemical weathering produces new materials.

only physical weathering creates smaller pieces of rock.

only physical weathering involves water.

chemical weathering is faster than physical weathering.

True

False

Humus is

the water in soil that makes it moist.

the dead plant and animal material in soil.

12.

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

weathering

erosion

deposition

dumptruck

13.

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

mechanical weathering

chemical weathering

erosion weathering

deposition

14.

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

mechanical weathering

chemical weathering

15.

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart. This is an example of:

mechanical weathering

chemical weathering

16.

How does freezing water cause the weathering of rocks? The freezing water—

keeps the rocks in place

makes the rocks last longer

expands cracks and breaks rocks

causes rocks to fall in landslides

17.

How do plants weather rocks?

during photosynthesis

when roots grow into cracks of rocks and expand the rock

when the plant moves water from the roots to the leaves

boulders

sediment

ice

mountains

19.

_________is the movement of sediment from one place to another.

Erosion

21.

What is sediment?

bits of rock, sand, and silt caused by the weathering of rocks

decaying plant or animal material

the process of rocks being broken down and carried away

the top layer of the soil

22.

When wind, water, or ice deposit materials in a location, this is known as:

Erosion

Weathering

Deposition

Moving Around

23.
