Temperature and pressure lead to the creation of magma, which is composed of melted rocks. Magma is an extremely hot liquid substance, with temperatures ranging up to 2400 °F.

Describe the mechanism of plate motion?
magma in the mantle rotates in convection cells. the magma then pushes the plates.
When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes.
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
magma
Is the following sentence true or false when solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
true
What is used to describe the continuous heating and cooling of magma in the mantle?
Mantle convection
Describe the mechanism of plate motion?

When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes.
What provides the force that causes magma to the surface?
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
magma
What does the mantle secrete?
Magma
Why are basalts produced on divergent plate boundaries?
As the plates diverge, upper mantle rock rises and undergoes decompression melting along the rift. Because the upper mantle is comprised of mafic rock, the subsequent melt of this rock produces a mafic magma. Basalt and its coarse-grained intrusive twin, gabbro, are produced when this mafic magma solidifies.
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
What layer of the earth has magma?
mantle
What is the magma chamber of the earth?
Mantle
What layer of earth has magma?
mantle
What is the difference between the magma and the mantle?
mantle is earth's layers there is 4 important layers crust, mantle, outer and inner core. Yet magma is volcano and more into that (:Karina:
