What is Made from melting plates?
Magma
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
How is liquid magma formed?
Melting rocks.
What replaces magma in the Earth?
The subduction and melting of oceanic crust replaces magma in the earth.
Why does the magma have to be hot?
Magma is molten rock. Rocks have very high melting temperatures.
What processes cause earth's rocks to turn into magma?
Melting.
What two processes produce the layer of dark brown to black soil?
(1) melting and solidification of magma
What happens when water is added to rock in the mantle?
It causes a lowering of the melting temperature of the material, which in turn can cause partial melting of the mantle material leading to the formation of magma.
How does magma occur?
Magma occurrs by rocks melting inside a volcano
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
What is Made from melting plates?
Magma
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
How is liquid magma formed?
Melting rocks.
What replaces magma in the Earth?
The subduction and melting of oceanic crust replaces magma in the earth.
Why does the magma have to be hot?
Magma is molten rock. Rocks have very high melting temperatures.
What does melting do to a igneous rock?
Melting causes an igneous rock to form into lava/magma.
Does magma erode igneous rocks inside a volcano?
In a way. A magma is hotter then the surrounding rock, that's why the magma is molten and the rock is not. But because of this, some heat of the magma is melting the surrounding rock. You might want to classify this as erosion, but it's simply the melting of the rock surrounding the magma.
