The satellite photograph shows geological features, including a glacier.

As the glacier melts, water travels toward the ocean along the geological feature labeled X. When water erodes soil along this feature, the feature will most likely become —

• straight

• dry

• shorter

• wider

Which answer choice best explains the change from daytime to nighttime on Earth?

• The sun stops sending light to Earth at night.

• Earth moves farther away from the sun at night.

• The tilt of Earth causes less light to reach Earth at night.

• Earth rotates and causes different parts of Earth to experience night.

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

Ocean currents affect weather patterns by —

• regulating when tides occur in coastal areas

• trapping heat at the equator to regulate the global climate

• distributing heat from the uneven absorption of solar energy

• increasing the rate of evaporation to transport water to areas experiencing droughts
