What is crust ?

“Crust” describes the outermost shell of a terrestrial planet. ... Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.

Thickness :

Earth's crust is 5 to 70 km thick. Continental crust makes up the land on Earth, it is thicker (35 - 70 km), less dense and mostly made up of the rock granite. Oceanic crust makes up most of the ocean, it is thinner (5 - 7 km), denser and mostly made up of the rock basalt.

Temperature:

Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit). Billions of years ago, the planetary blob that would become the Earth started out as a hot, viscous ball of rock.29-May-2015

Average Temperature:

The temperature of the crust increases with depth, reaching values typically in the range from about 500 °C (900 °F) to 1,000 °C (1,800 °F) at the boundary with the underlying mantle. The crust and underlying relatively rigid mantle make up the lithosphere.
