25.
A stream that flows into a larger stream.
a)
rilly
b)
river
c)

26.
Which of the following is NOT a type of chemical weathering?
a)
water
b)
carbon dioxide
c)
ice wedging
d)
living organisms secreting acid to break down rocks
27.
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.
