7: Mod F, Unit 1, Lesson 1 Test

True/ False: All rocks are created equal.

• True. They are all exactly the same.
• False. Some are more resistant to weathering than other rocks.
• False. Some rocks are stronger and bigger than others.

A large rock will:

• Weather more slowly than smaller broken pieces of the same rock.
• Weather at the same rate as smaller broken pieces of the same rock.
• Weather faster than smaller broken pieces of the same rock.
• Not weather at all because of its size.

What is/are the main types of weathering?

• physical weathering and chemical weatering
• chemical weathering
• physical weathering

• none of the above.

Rocks can be physically weathered by:

• temperature changes
• pressure changes
• ineractions with plants, animals, water, wind, ice and gravity
• all of the above.

True/ False: Animals can physically weather rocks.

• True
• False

Acid precipitation on rocks, iron-containing rocks, plants growing on rocks- The above are examples of:

• Physical Weathering
• Chemical Weathering
• None of the above.

What causes rocks to physically weather?

• one cycle of freezing and thawing
• being in a warmer/ wet climate
• many cycles of freezing and thawing
• being in a warmer and dry climate

What causes rocks to chemically weather?

• one cycle of freezing and thawing
• being in a warmer/ wet climate
• many cycles of freezing and thawing
• being in a warmer and dry climate

Weathering is an important process that changes Earth's surface.

• True
• False.

What does erosion and deposition do to matter?

• Nothing.
• Breaks it down until it dissapears.
• Move and deposit it into new places
