Important points about the Interior Structure of the Earth

Image

Earth has a diameter of about 12756 km at equator & about 12715 km at the poles. The Earth’s interior consists of rocks & metals & has 4 layers.

1. The Crust or the top layer of the earth.

It sustains life on the earth. It is made of igneous rocks, metamorphic rocks & sedimentary rocks. The crust is made of 2 layers—

(1) outer layer orsial which is made of silica & aluminum

(2)  inner layer or sima made of basalt & magnesium.

2. Mantle is the 2nd Layer of the earth made of silicate rocks rich in iron & magnesium. The mantle is divided into upper mantle and lower mantle.

Upper mantle consists of lithosphere & asthenosphere. Lithosphere is the hard rock layer of the mantle& the asthenosphere hemisphere is made of viscous yet solid rock.

Outer core – made of liquid iron & nickel.

Inner core- innermost & deepest Layers It is extremely hot with high pressure and this causes the contents of the inner core to remain solid.

Facts:-

The crust forms only 0.5 % of the volume of the Earth, 16% consists of the mantle & 83% makes up the core.

The radius of the Earth is 6371 km

Core is also called “nife” as it made of ni-nickle & fe-iron (ferrous)

The crust of the earth is made of various types of rocks (natural mass of mineral matter).

Rocks are of different colour, size, texture.

There are 3 major types of rocks

Igneous

Sedimentary

Metamorphic

Atmosphere

By Victor S. Fischer
An  atmosphere  is a layer of gases surrounding a planet or other material body of sufficient mass that is held in place by the gravity of the body. A tmosphere The envelope of air that completely surrounds the earth is known as atmosphere. The atmosphere extends to about 1000 km from the surface of the earth. But 99% of the total mass of the atmosphere is found within 32 km. This is because the atmosphere is held by the  gravitational pull of the earth . Composition of the Atmosphere (i)  Nitrogen - 78% (ii)  Oxygen - 21% (iii)  Argon -0.93% (iv)  Carbondioxide - 0.03% (v) Neon - 0.0018% (vi)  Helium - 0.0005% (vii)  Ozone - 0.0006% (viii)  Hydrogen - 0.00005% Carbon dioxide is present in small quantity in the atmosphere It is an important constituent of air because it has the ability to absorb heat and thus keep the atmosphere war...
