Earth’s Climate Has Always Changed

How does weather differ from climate?

• Weather can change, but climate can't.

• Weather and climate are the exact same thing.

• Weather describes precipitation; climate describes temperature.

• Weather is measured from day to day; climate is the average weather over a long period of time.

Distance north or south of the equator is measured by

• latitude.

• longitude.

• elevation.

• tropical zones.

How does latitude affect climate?

• The closer to the poles, the warmer it gets.

• The higher you go up a mountain, the colder it gets.

• The higher you go up a mountain, the warmer it gets.

• The closer to the equator, the warmer it gets.

Greenhouse gases, such as carbon dioxide and methane,

• help flowers grow in dry places.

• help water flow from place to place.

• are emitted by trees and other plants.

• hold heat in the atmosphere.
