Explanation:
The earths interior is divided into three main parts-
a) Crust
b) Mantle- Mantle is divided into upper mantle and lower mantle.
c) Core- It is also divided into two parts such as inner core and outer core.
<u>Crust is the uppermost layer of the earth that includes the surface</u> and up to a depth of about 7-40 km on average.
The upper mantle lies just below the crust. And<u> lithosphere refers to the crust and a small part of the upper mantle</u>. The <u>asthenosphere is the layer present below the lithosphere and here the rocks are solid but behave in a plastic manner. Rocks can move due to deformation. The lithospheric plates move over this region</u>.
The<u> lower mantle is the region that lies below the upper mantle and is the innermost layer of the two mantle</u>. Here the magma gets heated up due to the interior heat and rises up towards the upper mantle generating convection current.
<u>The outer core is comprised of molten rocks, mostly iron, nickel and is liquid in nature</u> whereas <u>the inner core has the same composition but is solid in nature and is denser than the outer liquid core</u>.
Lastly, the <u>geosphere is the entire region that is made up of all the above layers namely crust, core and mantle</u>.
