Our Earth
Our planet Earth is an extraordinary place. It is the only planet in our solar system that can support life. It is a complex and dynamic system that is constantly changing. In this article, we will explore some of the key features and characteristics of our Earth.
The Size and Shape of Our Earth
- Our Earth is the fifth largest planet in our solar system.
- It has a diameter of about 12,742 kilometers (7,918 miles) at the equator.
- The shape of our Earth is oblate spheroid, which means it is slightly flattened at the poles and bulges at the equator.
The Layers of Our Earth
- Our Earth is made up of several layers, including the crust, mantle, outer core, and inner core.
- The crust is the outermost layer and is about 5-70 kilometers (3-44 miles) thick. It is made up of solid rock and is where we live.
- The mantle is the layer beneath the crust and is about 2,900 kilometers (1,800 miles) thick. It is made up of hot, semi-solid rock.
- The outer core is about 2,250 kilometers (1,400 miles) thick and is made up of liquid iron and nickel.
- The inner core is about 1,220 kilometers (760 miles) thick and is solid due to the immense pressure it is under.
The Atmosphere of Our Earth
- The atmosphere of our Earth is a thin layer of gases that surrounds our planet.
- It is made up of about 78% nitrogen, 21% oxygen, and 1% other gases like carbon dioxide and argon.
- The atmosphere protects us from harmful radiation from the sun and helps regulate our planet's temperature.
The Water on Our Earth
- Water covers about 71% of our Earth's surface.
- Most of this water is in the form of saltwater in our oceans.
- Only about 3% of the water on our Earth is freshwater, and most of that is frozen in glaciers and ice caps.
- Water is essential for all life on our planet.
The Tectonic Plates on Our Earth
- The crust of our Earth is made up of several tectonic plates that move and interact with each other.
- These movements can cause earthquakes, volcanic eruptions, and the formation of mountains.
- The study of these tectonic plates is called plate tectonics and helps us understand the processes that shape our planet.
