Question

What is the outermost layer of earth called?

Answer 1

Hint: Earth is one and only planet out of the eight planets which possess life. Earth is covered with \[70\%\] water and has a balanced atmosphere, to sustain life. Structure of earth is mainly divided in three parts, namely the Crust, Mantle and Core.

Complete step-by-step answer:
There are three layers in the Earth, namely the Crust, the Mantle, and the Core.

The crust is the outermost layer of the earth’s surface which accounts for less than \[1\%\] of the Earth’s volume. The crust of Earth is of two distinct types: Oceanic, composed primarily of denser rocks and Continental , mostly composed of less dense rocks. The crust is rich in natural resources. We live on the crusts. They are also fertile, leading to cultivation of agriculture.

Note: The Mantel is beneath the crust and adds about \[83\%\] to the earth’s volume. It is a hot and dense layer, making it appropriate for the formation of minerals. The core is the innermost layer; it is very hot and is rich in iron and nickel.
Earth is one and only planet out of the eight planets which possess life. Earth is covered with $70\%$ water and has a balanced atmosphere, to sustain life. The earth is neither too far nor too close to the sun, thus maintaining optimal temperature for life.
The earth takes \[365\] days,\[48\] minutes and\[45.68\] seconds to revolve around the earth, thus we have \[365\] days a year. The extra \[48\] minutes and \[45.68\] seconds adds up for \[4\] years, to make extra \[24\] hours which is called the leap year. The earth takes \[23\] hours,\[56\] minutes and \[4.09\] seconds to rotate on its own axis, thus making a day.
