A net torque of magnitude is 600
<span>Determined by the distance between objects and the difference in mass between the objects is gravity or gravitational force. Gravity is dependent on those two factors, and is what causes objects on Earth to stay on the ground. It is defined as the "pull" that an object with mass exerts on another object that makes the latter gravitate towards the former. Weight is the measure of gravitational force exerted by a mass.</span>
<span>Crust: The thin, outer layer of the earth. Less than 1% of the Earth's mass.Made of solid rock, broken into plates.
Mantle: Molten rock on which plates float. Contains 67% of the earth's mass.

Core: Inner layer of the Earth. Made of both solid and liquid metals.</span></span>
