The sun appears to move across the sky each day. This movement of the sun can best be explained by Earth's

• revolution around the moon

• revolution around the sun

• rotation

• tilt on its axis.

The sun is just an averaged sized star. Other stars are like the sun, but they look like points of light in the night sky because they are

• smaller than the Sun

• farther away than the Sun

• white dwarf stars

The Moon orbits the Earth and the Earth orbits the Sun. The force responsible for these orbital movements is

• friction

• inertia

• gravity

The repeating pattern of "changing shape" of the moon, which is caused by the amount of the Moon's surface illuminated by the Sun at different times during the 28 day cycle are called

The length of our year is determined by

• Earth's tilt

• Earth's rotation

• Earth's orbit around the Sun

• Moon's orbit around the Earth

We can see the moon most nights in the sky because

• shines like a star

• absorbs the light from the stars

• has volcanic eruptions

• reflects the Sun's light
