Why does the amount of daylight change during the course of a year?

• The amount of light and heat radiated by the Sun changes at different times of the year.
• The distance between the Sun and Earth changes from summer to winter.
• The North Pole points more toward the Sun at one time of the year than another; while the South Pole is further away.
• Earth rotates at different speeds at different times of the year.

The northern hemisphere experiences summer in June, July, and August because

• the Earth is closest to the sun during these months.
• the Earth is orbiting the sun faster during these months.
• the northern hemisphere is tilted toward the sun during these months.
• the northern hemisphere is tilted away from the sun during these months.

What is the main cause of seasons on Earth?

• the distance between Earth and the sun
• the tilt of Earth’s axis and the revolution of the Earth around the sun
• the orbit of Earth
• the rotation of Earth

Which statement best explains how a lunar eclipse occurs?
