Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can best be concluded from this information?

• The movement of continental plates is caused by volcanic eruptions.

• The oceans are becoming deeper and warmer as more rocks are produced.

• The shape of Earth’s lithosphere is continually changing.

• The rocks on the ocean floor are producing tectonic plates that are converging.

A student studies these two illustrations of the same area of land in the southern United States. The student concludes that a drought caused the stream to become dry. Which other explanation is MOST plausible to account for the difference between the illustrations?

• The water table beneath the stream moved to the surface.

• The stream banks became too eroded to hold water.

• The direction of water flow in the stream reversed.

• The stream changed course farther upstream.
