2 Parts: One complete revolution of Earth around the Sun takes about ______ and one rotation takes about _______. 

• 365 days; 24 hours
• 1 day; 1 year
• 24 hours; 365 days
• 365 hours; 24 days

Earth has seasons because

• it rotates on its axis exposing 1/2 to sunlight and 1/2 to darkness
• its axis is tilted as it revolves around the sun leading to a differential of direct sunlight
• the distance between Earth and the sun changes; when we are closer, we are hotter
• the temperature of the sun changes.

We experience this season when the Northern Hemisphere is located closest to the Sun?

• spring
• summer
• fall
• winter

An equinox occurs when

• the equator is receiving the most direct sunlight (directly above)
• the Northern Hemisphere is tilted away from the sun.
• the Northern Hemisphere is tilted toward the sun.
• Earth's axis is parallel to the sun's rays.

Why does the area near the equator experience such a small range of temperatures throughout the year?

• The equator rotates slower than the poles.
• The equator remains the same distance from the Sun.
• The equator always receives direct sunlight.
• The equator is closer to the Sun.

When the North end of Earth’s axis is tilted toward the sun, North America will experience ______?

• more indirect rays and shorter days.
• more indirect rays and longer days.
• more direct rays and shorter days.
• more direct rays and longer days.

In which seasons does the Earth neither tilt toward or away from the sun?

• summer and winter
• summer and fall
• spring and fall 
• spring and winter

What occurs when the tilt of the Earth causes the length of the day to be longer or shorter?

• a solstice
• an equinox
• a tide
• an eclipse

What is rotation?

• the spinning on an axis
• the orbit around another object
• any type of movement
• spinning and orbiting

_________ hours is how long it takes for the Earth to complete 1 full rotation.

• 26
• 12
• 24
• 6
