Earth Moon and Sun (7th Grade Science)

One complete revolution of Earth around the sun takes about

• one rotation

• one year

• one eclipse

Earth’s rotation takes about

• 365 days

• 24 hours

• 1 month

Day and night are caused by

• the tilt of the axis

• Earth's rotation on its axis

• Earth's revolution around the sun

Earth has seasons because

• the distance between earth and the sun changes

• its axis is tilted as it moves around the sun

• the temperature of the sun changes

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

• less direct rays and longer days

• more direct rays and shorter days

• more direct rays and longer days

From new moon phase to full moon phase, you see

• an increasing amount of the lighted side of the moon

• a decreasing amount of the lighted side of the moon

• the same amount of the lighted side of the 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

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

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

• New Moon
• Waxing Gibbous

• Full Moon

When are tides highest?

• during the moon’s first quarter phase

• when the sun, Earth, and the moon are nearly in a line

• when the moon is at a right angle to the sun

Tides are caused mainly by

• differences in how much the sun pulls on different parts of Earth.     

• strong winds blowing water onto coasts.

• differences in how much the moon pulls on different parts of Earth.
