11.
The process that breaks down rocks and other materials on Earth's surface is called
a)
weathering
b)
erosion
c)
soil conservation
d)
decomposition
12.
Which type of climate will have faster chemical weathering?
a)
Hot and Wet
b)
Cold and Dry
c)
Hot and Cold
d)
Cold and Wet
13.
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 _____.
This statue was probably destroyed by _____.
a)
Wind
b)
Humans
c)
Acid Rain
d)
Animals
14.
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?
After hit with acid rain, tiny cracks form. Does this make it more likely or less likely to break apart?
a)
More Likely
b)
Less Likely
15.
How do plants weather rocks?
a)
during photosynthesis
b)
when roots grow into cracks of rocks and expand the rock
c)
when the plant moves water from the roots to the leaves
16.
