Why do Doctors wear white medical jackets over their regular clothes?
Gravitation is a phenomenon through which all objects attract each other. Modern physics describes gravitation using the general theory of relativity, but the much simpler Newton's law of universal gravitation provides an excellent approximation in many cases. Gravitation is the reason for the very existence of the Earth, the Sun, and other celestial bodies; without it, matter would not have coalesced into these bodies and life as we know it would not exist. Gravitation is also responsible for keeping the Earth and the other planets in their orbits around the Sun, the Moon in its orbit around the Earth, for the formation of tides, and for various other natural phenomena that we observe.

Earth has a molten iron core,we get charged particle from the sun and solar winds.The Auroora on the north and south poles recharge the earth magnetic fields.which in turn helps form and protect gravitational forces on earth.
Any object has intrinsic gravity consistent with its mass and we can't do anything to change or control it. At least until now.

Easy answer: we do not know what causes gravity (and we do not know how to control it). There are two groups of theories: Gravity as the result of a force-particle (a vector boson) being exchanged between any pair of particles. The exchange particle is called a graviton. Gravity as an effect of the geometry of space-time: the rubber sheet analogy (put a massive bowling ball on a rubber sheet: it will create a dip. Any smaller billiard ball placed on the rubber sheet will fall into the dip toward the larger ball). Relativity treats gravity as a geometry effect. It is better at predicting the effect of gravity on light waves. As photons have no rest-mass, the classical Newtonian approach (F G m1 m2 / d^2) predicts a force of zero (therefore, no exchange of gravitons?). However, the geometry of space-time will affect any moving particle, whether it has mass or not.
