Question

describe the internal structure of earth

Answer 1

INTERNAL STRUCTURE OF EARTH

*internal structure of earth May be most convincing describe with the help of seismic waves.

*internal structure of earth like layers/shells like an onion.

*nobody has done here.

*different materials transmitted by different seismic waves.

*on behalf of seismic waves the internal structure of earth is made up of

*core
*mantle

CORE

CORE is the densest of earth. it density is 12.5 and average density of earth is5.5.

INNER CORE

the existence of the inner core with radius of 1200km is discovered by LeAnn in 1936.

temperature is 4000c

composed of iron and nickel but they are In solid form because of very high pressure.

OUTER CORE

it is also composed of iron and nickel but they are in liquid form because of less pressure.

temperature is about 3700c

it's outer surface lies at 2900km below the sea level.

thickness is 2250km.

MANTLE

it is the second layer and cover mostly internal surface of the earth.

it is in viscous form.

composed of silicon rocks

it's density is 4.5

temperature is 1000c
