By maintaining it clean,not to make garbage and love mother earth by nature loving
Farmers used crop rotation to keep the earth fertile.
plates keep earth in motion
None. The moon orbits the Earth, Earth orbits the Sun. Inertia and the gravity keep the moon in the Earth's orbit.
Gravataional force is applied by the spinning of the earth.
Yes. Clearly the Earth orbits around the Earth.
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
The sun.
nothing
the earth's gravitational pull is just strong enought to keep it in orbit, but not strong enought, at that distance, to pull it back to earth
The gravitational force between Earth and the Sun provides the centripetal force needed to keep Earth in orbit. This force keeps Earth moving in a circular path around the Sun.
The sun warms the earth. The heat (energy) from the earth then heats the air.
no the earth does
