INSIDE OUR EARTH

Earth our homeland is a dynamic planet. It is constantly undergoing changes inside and outside. What do you think about what is inside the earth and what is the earth made up of ?

INTERIOR OF THE EARTH 
The earth is like on onion, just like you keep peeling of layers of an Onion, the earth is also divided into different layers.
The  uppermost layer of the earth is known as the crust. Now the uppermost means that there will either be an ocean somewhere or a continent somewhere. So in the continental area,you can say that the height of the crust is 35 km and in the oceanic area ,the height of the crust is 5 km. Now,if
we talk about its structure,then the continental region is made up of silica and aluminium.hence it is known as (si- al) and the oceanic region which is the crust is made up of silica and magnesium and is known as (si-ma) . 
The next is that the mantle is found just below the earth's crust. It is divided into three part.
first is the crust, second is the mantle and third is the core.the mantle is just below the crust and its height or depth is 2900 km and just like the crust is around on the upper surface of the earth, shape.  right after the mantle comes the core .
The triangle of the core is 35 kilometers. The core mantle and lithosphere together are 6371 kilometres and from this we can know that the triangle of the earth is 6371 kilometers.
And our core region is made of mukta, nickel and iron and so we also call it nibhaaye and nibhaaye means nickel and bhaaye means ferrous, meaning iron.

OUR CHANGING EARTH

LITHOSPHERIC PLATES the earth's crust is made up of many large and same small, rigid, irregularly shaped plates. These are like slabs that hold up the continents and the ocean floor. These are called lithospheric plates. ENDOGENIC FORCES AND EXOGENIC FORCES Th force which occur in the interior of the earth are called endogenic forces. And the forces which are generated on the surface of the earth are called exogenic force. Endogenic forces sometimes produce sudden motion and sometimes slow motion .               VOLCANO  1. Volcano are openings in the earth's crust that spew lava,ash and gases when tectonic plates move, they creat cracks in the earth's crust that allow magma to move the surface. 2. Volcano can be seen on lond or below the ocean, and can range in size from small vents to lorge mountain. 3. There are different types of volcanoes. Active volcanoes are those that have either erupted recently or are expected to do so in the near future...
