What is the hydrosphere?

Back

The hydrosphere is all the water on or surrounding the surface of the planet.

Front

Why does hot air rise?

Back

Hot air rises because it is less dense.

Front

What causes surface currents in the ocean?

Back

Wind causes surface currents.

Front

What happens to cold air?

Back

Cold air sinks because it is more dense.

Front

What happens to warm air?

Back

Warm air rises because it is less dense.

Front

Define the Coriolis Effect.

Back

The Coriolis Effect is the deflection of moving objects caused by the rotation of the Earth.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back.

Front

What is density?

Back

Density is the mass of a substance divided by its volume.

Front

How does temperature affect air density?

Back

As temperature increases, air density decreases; as temperature decreases, air density increases.

Front

What is the role of gravity in ocean currents?

Back

Gravity pulls water down, influencing the movement of ocean currents.
