Which is true of energy resource acquisition?

• Renewables are mostly acquired above Earth's surface & Non-renewables are acquired below Earth's surface

• Non-renewables are mostly acquired above Earth's surface & Renewables are acquired below Earth's surface

• Both renewables & non-renewables are mostly acquired below Earth's surface

• Both renewables & non-renewables are mostly acquired above Earth's surface

Saltwater intrusion can occur in aquifers near coastlines, when freshwater is displaced by saltwater. Aquifers are more vulnerable to saltwater intrusion when recharge rates are low or withdrawal rates are high. In which location would saltwater intrusion be a problem?

• a small coastal town experiencing a rainy summer

• a coastal agricultural area using periodic irrigation

• a large inland region of growing cities and farms

• a growing coastal city undergoing a drought
