Describe The Interior Structure Of Earth

The crust the mantle and the core. An outer silicate solid crust a highly viscous asthenosphere and mantle a liquid outer core that is much less viscous than the mantle and a solid inner core. Scientific understanding of the internal structure of earth is based on observations of topography and bathymetry observations of rock in outcrop samples brought to the surface from greater depths by volcanoes or volcanic activity analysis of the seismic waves that pass t.

A solid metal core made up of nickel and iron 2440 km diameter 2 the outer core.

Describe the interior structure of earth. The internal structure of the earth is made up of the asthenosphere the upper mantle the lower mantle the outer core and the inner core. The earth s interior consists of rock and metal. Structure of earth s interior is fundamentally divided into three layers crust mantle and core.

Crust it is the outermost solid part of the earth normally about 8 40 kms thick. By kimberly yavorski it is widely accepted that the earth s interior is composed of several layers. These structures support the crust of the earth.

Earth s core is thought to be composed mainly of an iron and nickel alloy. Earth has a diameter of about 12 756 km 7 972 mi. The inner core is under such extreme pressure that it remains solid.

This composition is assumed based upon calculations of its density and upon the fact that many meteorites which are thought to be portions of the interior of a planetary body are iron nickel alloys. The interior structure of the earth is composed of three main layers. It is made up of four main layers.

1 the inner core. The core is composed mostly of iron fe and is so hot that the outer core is molten with about 10 sulphur s. A liquid molten core of nickel and iron 3 the mantle.

Dense and mostly solid silicate rock. Inner core outer core mantle and crust. The internal structure of earth is layered in spherical shells.
