Explanation: Our earth plays a dynamic role. The size of the earth is huge and comprised of a huge mass. Both the composition as well the gravitational force is equally important in understanding the complex mechanisms or processes that undergoes outside and within it.
It is due to the the gravitational pull that helps the moon to maintain its orbital path around the earth and so are people grounded to the top of the crust. Earth's atmosphere is comprised of various gases and are found to exist today from the time of its formation.
The internal heat of the earth is also equally important that maintains the total heat budget of the earth along with the heat generated from the incoming solar radiations. This is a continuous process that changes over a certain time period
The Earth's Mass is what directly influences its gravitational pull. The gravity produced by the earths mass keeps people grounded on earth and the moon in orbital rotation by pulling to the center of mass, the Earth's core.
