How does the water cycle influence Earth's climate?

• By creating mountains

• By affecting humidity and weather conditions

• By melting glaciers

• By forming rivers

Why are inland regions like Arizona usually not humid?

• They have more rain

• They are closer to the ocean

• There is very little water vapor in the atmosphere

• They have more glaciers

How can glaciers change the landscape?

• By creating deserts

• By carving valleys and creating mountain peaks

• By causing rain

• By increasing humidity

What does glacial retreat limit?

• The amount of fresh water that exists on Earth
