    Neither.

    Gravity is the result of the physical mass of the Earth. The rotation is a vestige of the how the proto-earth gathered surrounding material as it formed (the stuff falls in). But it is gravity that determined how that happened so indirectly the spin of the earth is due to the effects of gravity.

    Gravity does determine the path of the orbit the earth takes around the sun

    Gravity does determine the path of the orbit the moon takes around the earth

    Gravity did cause the moon to 'lock' to the earth where it only shows one side to us - in other words it spins once on its axis in exactly the same number of days that it takes to orbit the earth.

    Gravity is the result of the rest mass of the earth within the fabric of space. As an illustration; the earth is like a heavy soccer ball upon a loose trampoline, except space wraps all around or engulfs the planet earth.

    Gravity is the result of MASS, not rotation.

    Rotation is the result of motion, not gravity.

    The two are unrelated.

    The earth would have gravity whether it rotated or not.

    (Your weight on earth varies slightly from pole to equator due to

    the centrifugal force from the rotation, but the gravity doesn't change.)

    Neither.

    Gravity is caused by Earth's mass. It would have gravity even if it did not rotate.

    Rotation is not caused by gravity. Earth could rotate even if it had no gravity.

    The two are not related. The earth has mass therefore gravity. The fact that the earth spins is irrelevant here.

    Neither.

    The "source of gravity" is "stress-energy". Stress-energy includes all types of energy, but is mostly the rest mass of particles.

    The Earth's rotation is just the result of conservation of angular momentum since the time the Earth was formed.

    Neither. Gravity is an inherent property of all matter that has mass, and has nothing t do with whether it rotates or not.

    Gravity is created by mass it has nothing to do with rotation. Everything that has mass has gravity
