Question

explain the structure of the earth with the help of diagrams

Answer 1

The structure of the Earth is divided into layers. These layers are both physically and chemically different. The Earth has an outer solid crust, a highly viscous mantle, a liquid outer core, and a solid inner core.The shape of the earth is an oblate spheroid, because it is slightly flattened at the poles and bulging at the equator

The boundaries between these layers were discovered by seismographs which showed the way vibrations bounced off the layers during earthquakes. Between the Earth's crust and the mantle is a boundary called the moho. It was the first discovery of a major change in the Earth's structure as one goes deeper.

Answer 2

Structure of the Earth The interior structure of the Earth silicate Silicate minerals solid crust Crust (geology) is layered in spherical shells: an outer viscous Viscous asthenosphere Asthenosphere and mantle Mantle (geology) , a highly outer core Outer core , a liquid inner core Inner core that is much less viscous than the mantle, and a solid topography Topography and . Scientific understanding of the internal structure of the Earth is based on observations of bathymetry Bathymetry rock Rock (geology) in outcrop Outcrop , observations of , samples brought to the surface from greater depths by volcanoes Volcanoes or volcanic activity Volcanic activity , analysis of the seismic waves Seismic wave gravitational Gravity of Earth and that pass through the Earth, measurements of the magnetic fields Earth's magnetic field of the Earth, and experiments with crystalline solids at pressures and temperatures characteristic of the Earth's deep interior.
