Unit 7: Resources & Freshwater

Benjamin and Mia are discussing how different energy resources are acquired. Which is true of energy resource acquisition?

• Renewable resources are mostly acquired above Earth’s surface. Nonrenewable resources are mostly acquired below Earth’s surface.

• Nonrenewable resources are mostly acquired above Earth’s surface. Renewable resources are mostly acquired below Earth’s surface.

• Both renewable resources and nonrenewable resources are mostly acquired below Earth’s surface.

• Both renewable resources and nonrenewable resources are mostly acquired above Earth’s surface.

An aquifer in which of the following areas would be most affected by saltwater intrusion?

• a small coastal town experiencing a rainy summer

• a coastal agricultural area using periodic irrigation

• a large inland region of growing cities and farms
