Give eight points of differences between the Crust, Mantle and Core of the Earth
Answers
Answer:
The core, the innermost layer, is rich in iron and very dense. ... Most of the mantle is a thick fluid that moves in currents, but the very outermost portion of the outer mantle is solid. This portion and the solid crust . ... The crust makes up less than 1% of Earth's volume.
Answer:
The internal structure of Earth is layered in spherical shells: an outer silicate solid crust, a highly viscousasthenosphere 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 through Earth, measurements of the gravitational and magnetic fields of Earth, and experiments with crystalline solids at pressures and temperatures characteristic of Earth's deep interior.
