​I can explain what causes day and night.

By Courtney Moreland

Multiple Choice

What causes day and night?

• The earth traveling around the sun.

• Shadows

• The earth spinning on it's axis.

• The moon revolving around the earth.

Whenever the earth is facing the sun we will have day and when we are turned away we will have night.

If you said that day and night is caused by the earth's rotation, you are correct.

Multiple Choice

What would happen if the earth rotated faster?

• Summer would last longer

• Our days would be shorter.

• Our nights would be longer.

• Our year would be shorter.

Does that mean that our years would be shorter?

If they earth rotated faster on its axis that would effect how long we are facing the sun. If we were to spin faster our days and nights would be a lot shorter.

NO, because our years are determined by how long it takes the earth to travel all the way around the sun.
