Earth is the third farthest planet from the sun. It is bright and bluish in appearance when we see it from outer space. Water covers 70% of the earth while land covers 30%. Moreover, the earth is the only planet that can sustain life.

We can protect the earth by limiting the use of non-renewable resources. Further, we must not waste water and avoid using plastic.

In fact, water covers 70% of the surface. It includes the oceans that you see, the rivers, the sea and more.

Thus, the remaining 30% is covered with land. The earth moves around the sun in an orbit and takes around 364 days plus 6 hours to complete one round around it. Thus, we refer to it as a year.

Just like revolution, the earth also rotates on its axis within 24 hours that we refer to as a solar day. When rotation is happening, some of the places on the planet face the sun while the others hide from it.

As a result, we get day and night. There are three layers on the earth which we know as the core, mantle and crust. The core is the centre of the earth that is usually very hot. Further, we have the crust that is the outer layer. Finally, between the core and crust, we have the mantle i.e. the middle part.
