ice wedging

living organisms secreting acid to break down rocks

What are the two factors that affect the rate at which weathering occurs?

climate and mass of rock

climate and size of rock

type of rock and size of rock

type of rock and climate

Which of the following is NOT a type of physical weathering?

burrowing plants

ice wedging

acid rain

The diagrams shows a natural process that weathers rock.
Which statement best explains why this process results in weathering?

frozen water acts as a solute

water expands when it freezes

the mass of water increases when it freezes

frozen water dissolves most types of rock

10.

What is mechanical weathering?

Process through which rocks are physically broken into smaller pieces.

Rocks are broken down through chemical changes.

Rocks are worn away from acid in plant roots.

Rocks broken down by machinery.

11.

Carbon dioxide (CO2) combines with water as raindrops fall through the atmosphere. This makes a weak acid, called carbonic acid. Carbonic acid is a very common in nature, where it works to dissolve rock. Pollutants, such as sulfur and nitrogen from fossil fuel burning, create sulfuric and nitric acid. Sulfuric and nitric acids are the two main components of acid rain, which speeds up chemical weathering.
This statue was probably destroyed by _____.

Wind

Humans

Acid Rain

Animals

12.

Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases Figure below. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.
After hit with acid rain, tiny cracks form. Does this make it more likely or less likely to break apart?

More Likely

Less Likely

13.

What is the agent of erosion?

Wind

Water (Rivers)

Waves

Ice (Glaciers)

Gravity

14.

Which of these is an example of erosion?

Light shinning onto a mountain

Rain breaking down rock

Wind blowing away sediment

All of the above

15.

How much time is taken to form 1 cm of soil?
