Essay On Earth | Our Beautiful Mother Earth Essay For Students
Earth is the only planet which has all the necessities required for the survival of living beings. Millions of species survive on this planet. It is the third planet of solar system after mercury and Venus. It is one of the eight planets that revolve around the sun.
Origin of Earth
Earth was formed 4.5 years ago. It came into existence as a solidified cloud and other gases that were left from the creation of sun. Initially, the interior of Earth stayed cool for so long. However, the continuous energy released through radioactive decay gradually heated Earth.
As a result of this, iron started melting and it reached the center and began to accumulate. This resulted in exploding volcanoes and flowing lava covered everything. Finally, the iron accumulated in the center as core.

There were depressions in the crust in which water got collected. This Water raised from the interior parts of planet due to volcanic eruptions. This collection of water lead to the formation of oceans. Now, the surface of Earth has changed greatly since its first formation.
Features of Earth
It revolves around the Earth at a distance of 93 million miles. It appears bright blue if observed from the outer space. It has a perfect intensity of temperatures. It is neither too cold nor too warm which makes it a perfect habitat for survival of different species.
Shape of Earth
The shape of the Earth is oblate sphere and not a true sphere which mean that it is squashed from top and bottom just like an orange.
Layers of Earth
Earth is made up of four layers; inner core, outer core, mantle and crust. The part of the Earth that is in the form of land is called crust. It includes oceans, rocks and mountains.
It is Earth’s thin, cold and rocky layer as compared to what lies beneath it. We live on this crust. It is made up of silicon, iron, calcium potassium and magnesium.
Mantle is Earth’s thickest layer and approximately 3000km in depth. It lies below the crust and surrounds the core. Since the temperature in this part is very high so the mineral matter is still in molten condition.
The outer core lies above the inner core. It is made from iron and nickel but it is a liquid layer which is responsible for Earth’s magnetic field.
This magnetic field acts as a protective shield around the Earth. The inner core also contains nickel and iron. It is too hot, around 5000 degree Celsius which is similar to the surface of sun.
Composition of Earth
The atmosphere of Earth is composed of 78% nitrogen, 21% oxygen and trace amounts of other gases. This atmosphere gets thinner when the distance from surface increases. Almost 75 percent of Earth is covered with water, 97% of which is saline in nature and just 3% is actually clean.
We use this 3% clean water for our basic needs. There are many natural resources on Earth like stone, sand, natural gases, metals oil and coal.
Rotation of Earth
Earth takes 365 days to complete its round around sun. It also rotates around its own axis and completes its rotation in 24 hours. In this rotation, we experience day when the earth faces sun and we experience night when it gets away from sun.
