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 $$70\mathrm{\%}$$ 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 $$1\mathrm{\%}$$ 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 $$83\mathrm{\%}$$ 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 $70\mathrm{\%}$ 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.
