Aleks [24]

Answer:

Axis - B

Rotation - E

Revolution - D

Latitude - A

Gravity - C

Explanation:

The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.

The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.

Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year

Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.

Gravity is the force that keeps things together. Large masses have gravity that attract other masses.
