Why do you think that earthquakes and volcanoes occur in these main geologically active zones?
As the old crust enters the mantle it brings volatiles such as water with it. This lowers the melting point of the rock around it.This melted material rises to the earths surface under pressure along with gases and may erupt in a volcano.
What is the ridge layer of earths surface made up of the crust and part of the mantle called?
lithoshpere
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
Did the upper mantle or core of earths surface drive the plate tectonics?
The mantle, being of a silly-putty-like consistancy, is responsible for the movement of the plates on earth's crust, or plate tectonics.
How does plate tectonics affect the mantle?
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
What happens when buoyant mantle material gets near earths surface?
The buoyant mantle material will not subduct under Earth's continental crust. Instead, it will form mountains.
What is under the earths surface and in the earths crust?
mantle
How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.
How do changes in heat energy affect the density of earths mantle material?

What is the thickest layer of earths surface?
The Mantle.
What is the largest layer of earths surface?
The mantle
How many mantle plumes are on earths surface?
22
What is the layer 100 km below the earths surface?
The mantle =)
What is the term of circular movement of material inside earths mantle?
Convection
What is the term of the circular movement of material inside earths mantle?
Convection
What is the opening on earths surface where magma from the mantle rises and flows out?
Valcano
What Layer of hot and solid material between the crust and Earths core?
It is the Mantle.
