Inside earth crust

Question Answer
Lithosphere the rigid outer part of the earth, consisting of the crust and upper mantle.
Oceanic crust Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition.
Continental crust The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores,
Asthenosphere The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km below the surface.
Mesosphere the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Mantle Mantle: is the part of the earth between the core and the the crust is the MANTLE. It is about 1,800 miles(2,900 km) thick and makes up nearly 80 percent of the Earth's total volume.The mantle is made up of magma and rock.
Outer core The outer core of the Earth is a fluid layer about 2,300 km (1,400 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.
Inner core inner core is the innermost part of a core, specif. a solid sphere in the middle of the fluid core such as the iron-nickel core of the Earth.
