Earth Science A Unit 3 - Seasons, Climates, and Biomes TEST Rev.

Seasons are caused by Earth’s

• orbit and tilted axis

• size and tilted axis

• distance from the sun and tilted axis

• distance from the moon and tilted axis

Generally the farther the latitude goes away from the equator

• the hotter it gets

• the colder it gets

• the longer the days get

• the greater the axis tilts

The 4 seasons happen because

• we are closer to the sun during summer and farther from the sun during winter

• the Earth’s tilt goes back and forth pointing left, then right

• the Earth’s tilt faces the sun at some times and faces away during other times

• the Earth rotates and revolves around the sun
