Which two processes commonly generate magma?
decompression melting and wet melting (the addition of volatiles) :)
Mafic magma is generated at divergent boundaries because of?
decompression melting
Where does most magma originate?
Most melts on earth originate from plate boundaries. These are areas where there is decompression melting or hydrous melting because of subduction zones.
What does heat allow melting to occur?
Because melting occur at high temperature; at this temperature bonds between particles are weaker.
What is the primary process involved in the formation of magma at a rift?
Decompression melting of extremely hot mantle rock as it rises toward the surface.
What causes melting of material under divergent plate boundaries Is it melting of rock recompression of rock freezing of rock or decompression of rock?
decompression of rock

decompression melting
When melting occur and what is it called?
Melting occur at the melting point. The solid is transformed in a liquid.
When does the melting point occur?
Melting occur when a solid starts to be a liquid.
Where does most magma originate?
Most melts on earth originate from plate boundaries. These are areas where there is decompression melting or hydrous melting because of subduction zones.
What can be expected to occur as climate change continues on earth?
the earth's temperature will continue to rise which will increase the amount of sea ice that is melting. This will cause coastal flooding
When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes.
What is decompression melting?
A decrease in pressure, just as a rise in temperature, can melt materials, specifically rocks in this case. Therefore, decompression melting takes place as a result of less pressure being exerted on rocks. This occurrance is common at mid-ocean ridges where rocks are uplifted and consequently have less overburden.
Higher melting point than expected?
It is indeed possible for a substance to have a higher melting point than expected. This normally happens when the substance is impure.
What does heat allow melting to occur?
Because melting occur at high temperature; at this temperature bonds between particles are weaker.
What is the primary process involved in the formation of magma at a rift?
Decompression melting of extremely hot mantle rock as it rises toward the surface.
