Unit 1 Summative Remediation - Environmental Science - Spring 24

The Flint River in Georgia starts near Hartsfield Jackson Airport and runs all the way to Florida where it joins the Apalachicola River and eventually ends in the Gulf of Mexico. However, because the river starts so close to the airport, it has high levels of pollution from fuels, oils, coolants, and other transportation related chemicals that have leaked into the river.  This would be an example of what kind of pollution?

• Biological pollution, because it is pollution caused by living things

• 1. Point source pollution, because we know the pollutants are coming from the airport

• 1. Nonpoint Source pollution, because the pollutants are added to the river by rain water runoff

• Thermal pollution, because the pavement and concrete heat the ground around the river

Sinkholes occur when

• too much weight above an aquifer causes it to cave in.

• the water level in an aquifer rises, pushing through to the surface.

• excessive water use lowers a water table and causes subsidence.

• new aquifers form.

What is the main purpose of the Clean Water Act?

• 1. To prevent water pollution in the United States

• 1. To keep public drinking water safe throughout the world

• To store clean water for emergencies within the United States

• To make sure all people in the world have clean water to drink

Pollution that enters a water source directly through a pipe or other discharge outlet is called __________ pollution.

• Runoff

• Direct Source

• Point Source

• Nonpoint Source

Many people that live in the desert area of the United States (Southern California, Arizona, New Mexico, Utah) do not have grass in their yards.  Instead of traditional landscaping, they have xeriscaping- rocks, different types of cactuses, succulents, and other climate-appropriate plants. Why might people who live in these places choose this design?

• 1. This type of landscaping requires much more water to begin but not as much over time

• 1. This type of landscaping chooses plants that are not native to the area

• 1. This type of landscaping is designed to save water and requires little to no irrigation

• 1. This type of landscaping is actually harmful to the environment and they should not use it
