During a solar eclipse, the _____________ casts a shadow on ___________.
During a solar eclipse, the MOON casts a shadow on EARTH.

What causes the apparent rising and setting of the moon?
The Earth's rotation on its axis.

What would happen to the Earth if the gravity of the sun was taken away?
The Earth would no longer orbit the sun or rotate after 8 minutes because this is the amount of time it would take the gravitational pull of the sun to reach Earth.

A) What would happen to the Earth if the gravity of the sun was increased?
B) What would happen to the Earth if the gravity of the sun was decreased?
A) The sun's gravitational pull on Earth would increase, making things heavier.

Which motion of the Earth around the sun causes day and night?
The rotation of the Earth on its axis.

Explain what causes the different seasons on Earth. Describe how that affects the seasons in the different hemispheres.
The Earth's tilt and rotation cause the different seasons on Earth due to the amount of direct and indirect rays a part of the Earth receives.
Opposite hemispheres experience opposite seasons because the tilt affects the amount of direct and indirect rays a part of Earth receives.

What causes an eclipse?
An object in space casts a shadow on another object.

As the moon orbits the Earth, what explains why we see a waxing half/first quarter moon from Earth?
The moon reflects light from the sun on one side, so it looks like half of the moon is lit from Earth.
