Which of the following is the best explained by understanding that Earth rotates on its axis once each day?

• The change in the appearance of the Moon during the month

• The difference in seasonal temperatures during the year

• The apparent motion of the Sun through the sky

• The movement of water through the water cycle

How long does it take Earth to rotate on its axis once?

Observations of sand dunes, like the one in the Mojave Desert pictured here, reveal two characteristics of the dunes. First, sand dunes have a long side with a gentle slope and a short side with a steep slope. Second, they tend to move from one place to another over time. Which of the following best explains the cause of these characteristics?

• Deserts tend to be very hot year round.

• Wind shapes and moves the sand dunes.

• Rain creates the unique form of sand dunes.

• Temperature changes break up large desert rocks.

Students wanted to model the way water erosion can create certain landforms. They let water pour in a thin line over a salt brick for half an hour. The diagram above shows how the brick changed. Which of the following best describes the real-world landform they modeled?

• A delta created by stream deposits

• A canyon carved by a river

• A mountain built by folding rock layers

• Alake filling up with glacial meltwater
