The earth is the garden planet of the universe. So far, it is the only planet that can support life and it dies so in extraordinary profusion, abundance, and variety. It does not support life from its own resources alone. The earth tool shape at just the tight distance from the sin, close enough for the sun’s heat and energy to make condition hospitable for life, and yet now so close as to smother everything. As happened in the case of Mercury and Venus.
Scientist estimated that the Earth came into being about 4.6 billion years ago. Originally it was cold; however, the interior began to heat is under gravitational pressures. Theses pressures were great enough to light a nuclear core, as happened in the star. Rather the increased temperature and pressures led to the formation of a molted nickel and iron core. In this way the planet began to take on a stratified shape during its early evolution. Heavy metal sank to the center and lighter metals rose to the top. This top layer, the Earth’s crust, is a relatively thin skin of rich with lighter metals riding on the mantle below. Many geologists today believe that the crust is made up of a number if plates which drift apart and collide, thrusting up mountains like the Andes in Latin America and most to the volume of the Earth and extending from 20 or 30 kilometer to 2,000 kilometers. Below the mantle is the core.
The Earth is not sedate today, and certainly was not so in its infancy, numerous rings of volcanoes all round the world continually release gases and magma to create over million of years the atmosphere and the oceans. The stabilization of the oceans was a significant
