Essay on The Earth in English Earth is the planet we live on. It is the third planet from the Sun. It is the only planet where human and other species can live. Essential substances like air, water and land supports life on earth. The Earth formed around 4.5 billion years ago.
Earth and the resources of earth make life possible on it. If we were to imagine our lives without these resources, that would not be possible. As life cannot function without sunshine, air, vegetation, and water. However, this is soon going to be our reality if we do not save the earth now.
To say that saving the earth is the need of the hour would be an understatement. All the activities of humans driven by greed and selfishness have caused immense damage to the earth. It is degraded it beyond repair. Almost all the natural resources are now polluted due to these activities.
When all these resources will be under threat, naturally lives of all living organisms will be under peril. This is why we need to save the earth at all costs. All the other issues are secondary and saving the earth is the main concern. For when the earth will not remain, the other issues will go away automatically.
Earth is the only planet which can sustain life on it. We do not have a planet B which we can move onto. This makes it all the more serious to save the earth and save our lives. If we do not take strict actions now, we will lose the chance of seeing our future generations flourish forever. Everyone must come together for the same causes, as we are inhabitants of this planet firstly and then anything else.
Answer:
Earth is the only planet of the solar system that provides all the necessities required to survive. In short, it is the only planet that has life on it. It is the third planet of the solar system and the fifth largest planet among all the planets. This earth essay for kids is quite helpful for classes 3 to 6. Students will get to know more about planet earth. Kids from ages 6 to 15 will easily understand it. This essay will also help them to achieve good marks in exam or essay competition.
Introduction to the planet “The Earth”
Earth is an integral part of the solar system. It gets heat and light from the sun. If you look at the globe, most of the surface is covered with water i.e. approximately 71%. The rest 29% is covered by lands. Among this 71% water, only 3% is fresh water and the rest 97% is salted water of oceans and seas.
The Earth is surrounded by 6 layers known as its atmosphere. Earth’s atmospheric layers are- troposphere, stratosphere, mesosphere, thermosphere, exosphere, and ionosphere. The Earth’s atmosphere is composed of various gases like nitrogen (78%), oxygen (21%), argon (0.97%) and CO2 (0.04%), water vapor, etc
Origin of the Earth
The origin of the Earth is believed to be almost 5000 to 6000 million years ago. The Earth came into existence in the form of condensed cloud and other gases. The Earth was made up of mainly iron and silicate and some other elements in its origin. Some of these elements were radioactive.
After millions of years from its origin, the Earth becomes hotter and hotter due to continuous energy release through radioactive decay. As a result, the iron started melting and eventually, it reaches the center. Finally, the iron accumulated at the core of the Earth.
Composition of the Earth
The Earth is covered with gaseous material known as the Earth’s atmosphere. We live under this atmosphere on the surface of the Earth. Earth is composed of a number of layers. The kids for class 3 to 6 can get the answer for the composition of the Earth here. They can further add it to the earth essay. The different layers of the Earth are as follows-
Crust
The crust is the outer layer or surface of the Earth where we live. The Earth’s crust is a thin layer as compared to other layers. The Earth’s crust is approximately 5 km thick in ocean bed and almost 70 km thick in the continents. The crust layer of the land or the continents is composed of silica & alumina, hence called “sial”.
Mantle
The next layer under Earth’s crust is known as the mantle. This layer is quite thick as compared to Earth’s crust, approximately 3000 km in depth. Mantle layer is composed of different silicate rocks consisting more of magnesium and iron.
Tectonic plates
This layer of Earth is quite sensitive. Tectonic plates are actually a kind of combination of both the Earth’s crust and outer mantle layer which is commonly known as the lithosphere. When there is any kind of tension created through the movements of these plates, it leads to natural disaster i.e. earthquake.
Outer core
The outer core of the Earth is composed of iron and nickel. This layer is very hot approximately 4400 to 5000+ degrees Celsius. The outer core of the Earth plays an important role in protecting us from the powerful solar wind. The outer core creates a magnetic field that acts as a protective shield around the Earth.
Inner core
The composition of the inner core is similar to outer core i.e. nickel and iron. The inner core of the Earth is under too much pressure. This layer is present very deep from the Earth’s surface. The inner core of the Earth is too hot almost 5000+ degrees Celsius quite similar to the surface of the Sun.
