A measure of time for one revolution of the Earth

• day

• year

The ___________ divides the Earth into a Northern & Southern Hemisphere

• axis

• equator

If the Earth was not tilted on its axis then

• day and night would not occur because the amount of sunlight would stay the same.

• the seasons would not occur because the amount of sunlight would stay the same.

This diagram shows that the Southern Hemisphere is receiving less direct sunlight, therefore it

• will experience higher temperatures than the Northern Hemisphere.

• will experience lower temperatures than the Northern Hemisphere.

• will experience the similar temperatures as the Northern Hemisphere.

This diagram shows that the Southern Hemisphere is receiving less direct sunlight, therefore it

• will experience an increase in temperatures and enter the season of summer.

• will experience a decrease in temperatures and enter the season of winter.
