Describe The Interior Structure Of The Earth

Earth has a diameter of about 12 756 km 7 972 mi.

Describe the interior structure of the earth. Interior structure of the earth. The earth s interior consists of rock and metal. Dense and mostly solid silicate rock.

The crust the mantle and the core. 1 the inner core. The interior structure of the earth is composed of three main layers.

It is made up of four main layers. A solid metal core made up of nickel and iron 2440 km diameter 2 the outer core. The mantle proper makes up most of the earth s internal structure.

The crust can be divided into. Structure of earth s interior is fundamentally divided into three layers crust mantle and core. The hard brittle crust extends from earth s surface to the so called mohorovicic discontinuity nicknamed the moho the moho is not located at a uniform depth but about 10 kilometers 6 miles below the seafloor and about 35 kilometers 22 miles beneath the surface of continents.

A liquid molten core of nickel and iron 3 the mantle. The inner core is under such extreme pressure that it remains solid. Earth s interior is generally divided into three major layers.

The interior of earth can be observed through direct evidence such as rock samples from mining deep ocean drilling project volcanic eruptions and indirect evidence such as seismic waves meteorite investigation gravitation force magnetic field etc. Another discontinuity separates the upper mantle from the lower mantle which then extends down to 1678 miles to the outer core. The crust is the outermost brittle solid part of earth ranging from 5 70 km.
