Weathering

• The breaking down of Earth's surface-

  can be caused by different things:

• Ice

• root wedging

• flowing water

• abrasion- rocks bumping and hitting each other

• wind

• weather

Erosion is:

After pieces of the Earth are broken down through weathering, those pieces are moved through erosion. It’s the process of moving things from one place to another.

Deposition

After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.

Multiple Choice

What is weathering?

• When it rains or snows.

• Process of breaking down of rocks into smaller pieces.

• Process of moving small pieces of rocks.

Multiple Choice

Multiple Choice

_________ is the process of breaking down rocks into sediments.

• erosion

• deposition

• weathering

Multiple Choice

What is a sediment?

• tiny pieces of weathered rock

• pollution

• chemical reaction

Multiple Choice

 

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

• keeps the rocks in place

• expands cracks and breaks rocks

• makes the rocks last longer

• causes rocks to fall in landslides

Multiple Choice

 

Statue of Liberty has changed colors over time because oxygen has caused the surface of the copper it is made of to change into a new chemical (just like copper pennies turn green). What kind of weathering is this?

• mechanical

• chemical

Multiple Choice

How do plants cause erosion?

• during photosynthesis

• when roots grow into cracks of rocks and expand the rock

• when the plant moves water from the roots to the leaves

Multiple Choice

Weathering and erosion are the same thing.
