The Structure of Earth’s Interior



About earth
Today we will tell you something about Earth. You know much thing about Earth but today we will discuss about Earth's interior. Earth is the third planet after Venus aside Sun in universe. Earth is one of the finest planets in whole universe and the only one where life exists. Earth is the home of not only humans but also thousands of creatures. Now discuss something about inner formation of Earth. Most of us knew about the interior of Earth, that originated from the study of seismic waves from earthquakes because the speed of the seismic waves depends on density, travel-time of seismic wave can also used for changing the map in density with depth, and also we can show the Earth is composed of several layers.

The Structure of Earth’s Interior
·         Inner interior of Earth: The inner part if earth is divided into three parts. The Crust, the Mantle and the Core. These three things make Earth's interior structure.

·         The Crust: The thickness of the outermost layer of Earth under continent is 25 km to 60 km, where it is 4 km to 6 km under the sea oceans. Continental crust is made from many different kinds of rocks.

·         The Mantle: Another layer of Earth is Mantle which lies just below to Crust, it is dense and extending to 2890 km in depth. Mantle Layer is so dense that it is made of rocks like silicate. Both the P- and S- waves from earthquakes travel through the mantle, demonstrating that it is solid.

·         The Core: It is a depth of 2890 km and the boundary between the mantle and the Earth's core. The core composed iron. It exists because it refracts seismic waves creating a 'shadow zone'. CLICK HERE TO KNOW The Importance of Water in Life for Survival ... 
What is Earth Made up of

·         Earth Shedding Inner Layer: Earth and both moon and sun, do action with many other things.

·         Origin of Tide on earth: Moon is the only single Satellite, who had started revolution around Earth nearly three million years ago, and with its attraction force, it produced the ebb tide in the sea and the Earth's tilt pole stabilizes. It also makes Earth rotation is gradually slowing.

·         Origin of Oceans: According to some sources, millions years ago a comet dropped on Earth and played a important role in formation of the oceans.

·         The water on the Earth: There is 60% water on Earth and you can say that 60% Earth's part is covered by water. Earth is single planet in whole universe where water is exist in liquid form and we knew that water is so much important for survive on Earth.

·         Magnetic level of Earth: Earth has its own magnetic level and it is made by electrical shed.
