What is the rigid layer of the earths surface that is made up of the crust and a part of the upper mantle?
It's called the lithosphere.
Lithosphere is the layer clostest to the earths crust. It is the layer that contains the sial and sima. Asthenosphere is the next layer clostest to the earths crust. Mesosphere is the inner most layer of the mantle than it goes to the core... Outer core, and inner core.I learned about it in school XD
The mantle is under the earth crust and is made of mostly peridotite, which is a denser rock than that of the igneus, metamorphic and sedimentary rocks found in the crust. The crust ranges in temperature from 200 - 400 degrees Celsius the furthur towards the earths core one goes. The mantle however ranges in temperature from 500 - 900 degrees Celsius the furthur towards the earths core one goes. The mantle has two layers…
Earthquakes are caused by a shift in two different plates beneath the earths surface. The shift is usually caused by convectional magma flows underneath the earths crust. This is because the plates are purely floating slabs of rock on the magma beneath it. The layer beneath the crust is called the mantle.
The mantle is that part of the Earth between the crust and the outer core. It's upper boundary is at the base of the crust at a depth below the surface which can vary between 7 and 35 km. It extends all the way to the Earth's outer core at a depth of around 2890 km. the Earths mantle is located between the crust and outer core of the Earth. it is the thickest layer.
