The Earth wonders and mystery

There are several countries and continents on earth which including asia, America, Africa, Europe etc. the water is major part on earth with 79 percent occupied out of 100, And Land with 21 percent. there are several trees on earth which majorly provide oxygen for humans. The earth is the planet that we live on and it is the fifth-largest planet. It is positioned in third place from the Sun. . . . Our earth is the only planet that can sustain humans and other living species. The vital substances such as air, water, and land make it possible. The rocks make up the earth that has been around for billions of years. Similarly, water also makes up the earth. 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. The layer that we live on is the outer one with the rocks. Earth is home to not just humans but millions of other plants and species. The water and air on the earth make it possible for life to sustain. As the earth is the only livable planet, we must protect it at all costs.
