Earth in Space Practice

Earth's rotation takes about

• 365 days
• 6 months
• 24 hours
• 1 month

Day and night are caused by 

• the tilt of Earth's axis
• Earth's revolution around the sun
• eclipses
• Earth's rotation on its axis

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

Earth has seasons because

• it rotates on its axis
• the distance between Earth and sun changes
• its axis is tilted as it moves around the sun
• the temperature of the sun changes

The phase of the moon you see depends on

• where you are on Earth's surface
• how much of the sunlit side of the moon faces Earth
• how much of the moon's surface is lit by the sun
• whether or not an eclipse is occurring

From the new moon phase to full moon phase, you see

• an increasing amount of the lit side of the moon
• a decreasing amount of the lit side of the moon
• the same amount of the lit side of the moon
• more of the lit side, then less of the lit side of the moon

Because the moon rotates once for each revolution around Earth,

• you see some phases more than others
• a different side of the moon faces Earth each day
• you never see the far side of the moon from Earth
• the far side of the moon in visible only during the full moon phase

The amount of the lit side of the moon you can see is the same during

• new moon and full moon phase
• new moon and first quarter phase
• first quarter and third quarter
• full moon and third quarter

During what phase of the moon can a lunar eclipse occur?

• new moon
• first quarter
• waxing gibbous
• full moon

For a solar eclipse to occur, 

• the sun must be directly between Earth and the moon
• the moon must be directly between Earth and the sun
• the moon must be directly behind Earth
• Earth must be directly between the sun and the moon
