Assignment write about inside our earth with using suitable digrams
Answers
Answer: Most of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes. Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth.
The currently accepted theory of the Earth's structure is that it has a core (a solid inner core and a liquid outer core), a viscous mantle (divided into an upper mantle and mantle) and a silicate crust.
We have the inner core, outer core, mantle and crust which play an important role on Earth. The layers of the Earth are responsible for the formation of our continents. Two Hundred Fifty Million years ago most of the land mass was joined together forming a super continent called Pangaea.
Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.
In order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core are the parts of the earth.
