Farmers can best reduce negative effects on the water quality of nearby streams and lakes by planting crops that —

• produce less oxygen

• produce less carbon dioxide

• need less fertilizer

• need less solar energy

Which statement about the proposed law is supported by the model?

• The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake.

• The proposed law will not protect the lake because animals that live in or near the lake will add pollution to the lake.

• The proposed law will not protect the lake because groundwater will carry pollution from the wetland directly into the lake.

• The proposed law will protect the lake because the high elevation of the water table will block pollution from entering the lake.

How does the agricultural activity most likely affect the surface water of the area?

• Excess crop fertilizer is carried by runoff into the river, causing excess growth of water plants.

• Excess crop material accumulates on the riverbanks, slowing the movement of the river water.

• Crops reduce erosion, increasing the amount of soil entering the river.

• Crops absorb pure water from soil, causing the remaining water to contain more salt.

How do the industrial, agricultural, and residential activities of humans most likely affect the groundwater in the area?

• The activities prevent most of the water from evaporating into the atmosphere.

• Pollutants from the activities percolate through the soil and enter the water table.

• The activities replace the groundwater used.

• All of the above

A student sets up an investigation where water is poured through a coffee filter soaked with food coloring into a clear plastic cup filled with gravel. The colored water flows through the gravel and out the drain hole. The movement of colored water through the gravel best models —

• condensation of water vapor

• surface runoff of precipitation

• conservation of water

• pollution of groundwater

Scientists recently discovered that rocks collected from the Franklin Mountains in West Texas and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of —

• coastal erosion

• plate tectonics

• ocean currents

• glacial melting

Which table correctly compares features of divergent plate boundaries and convergent plate boundaries?

• Type of Motion: Plates move away from each other (Divergent), Plates move toward each other (Convergent); Landforms: Ridges and rifts (Divergent), Trenches and mountains (Convergent); Volcanic Activity: Yes (Divergent), Yes (Convergent)

• Type of Motion: Plates move toward each other (Divergent), Plates move away from each other (Convergent); Landforms: Ridges and rifts (Divergent), Trenches and mountains (Convergent); Volcanic Activity: No (Divergent), Yes (Convergent)

• Type of Motion: Plates move away from each other (Divergent), Plates move toward each other (Convergent); Landforms: Trenches and mountains (Divergent), Ridges and rifts (Convergent); Volcanic Activity: No (Divergent), No (Convergent)

• Type of Motion: Plates move toward each other (Divergent), Plates move away from each other (Convergent); Landforms: Trenches and mountains (Divergent), Ridges and rifts (Convergent); Volcanic Activity: Yes (Divergent), No (Convergent)

Which location is near a transform plate boundary?

• Location A

• Location B

• Location C

• Location D

Which type of boundary results in the spreading of the oceanic ridge?

• Convergent boundary

• Subduction boundary

• Transform boundary

• Divergent boundary

This picture shows scratches in bedrock that were caused by a moving glacier. These scratches are called glacial striations. Glacial striations in the bedrock of South Africa indicate that glaciers once moved across the African continent. The presence of glaciers on the surface of Africa is evidence that —

• the tectonic plate under Africa was closer to the South Pole at one time

• the equator was not always where it is currently located

• volcanoes did not exist until after faults occurred in Earth’s crust

• the location of the North Pole and the South Pole changed
