a)

True

b)

False; Land

5.

a)

Thermal pollution

b)

a)

True

b)

False; fossil fuels

15.

a)

chemical pollution.

b)

thermal pollution.

c)

eutrophication.

16.

How does eutrophication happen?

1. Wastewater (toilet, shower, sink) and fertilizer runoff gets into waterways

2. Extra nutrients grows from the wastewater and fertilizer

3. This extra nutrients causes the fast growth of algae over the surface of the water

a)

4. There is an increase in fish because they have so much algae to eat

b)

4. Too much algae reduces oxygen levels and the fish die
