Env. Science Semester Review

What is the relationship between groundwater and surface water?

• Surface water percolates through the soil to form groundwater.

• There is no relationship between surface and groundwater; they form independently.

• Groundwater filters through the soil to form surface water.

• Surface water is found in lakes directly above underground water sources.

Many areas of the world without adequate fresh water have become habitable because

• rainfall patterns have changed

• water management projects have diverted water to the area

• icebergs have been towed in to provide fresh water

• water conservation has been implemented

Which of the following represents nonpoint-source pollution?

• polluted wastewater from a chemical plant

• leaking oil tanker

• runoff from agricultural feedlots

Most of the pollutants in the ocean come from

• commercial boats and personal watercraft.

• spills from oil tankers.

• activities on land.

• leaking underground storage facilities.

Most large cities get water for households and industries from

• deep wells.

• rivers and lakes.

• pumps connected to springs.

• removing salt from sea water.

Which of the following might occur as a result of plastic trash accumulating in the ocean?

• Turtles mistake clear plastic bags for jellyfish, ingest them, and die of intestinal blockage.

• Sea birds are strangled by plastic six-pack rings.

• Sea mammals, such as seals, become tangled in clear plastic fishing lines and drown.

• All of the above

What pollutant forms when automobile emissions react with oxygen gas and ultraviolet rays?

• ozone
