Subduction zones, where one tectonic plate slides beneath another, tend to produce the greatest volume of magma. The intense heat and pressure created during this process can cause melting of the subducted plate, leading to significant magma production. This magma can rise to the surface and result in volcanic activity.
No. Water lowers the melting point of magma, both mafic and felsic.
Magma is molten rock. Rocks have very high melting temperatures.
The composition of the magma plays a significant role in determining its melting temperature. Magma with higher silica content tends to have a higher melting temperature. Pressure also affects the melting temperature; higher pressure usually results in a higher melting temperature. Water content can lower the melting temperature of magma by acting as a flux, allowing minerals to melt at lower temperatures.
decompression melting and wet melting (the addition of volatiles) :)
Melting.

This magma can rise to the surface and result in volcanic activity.
Pressure and heat that produce magma are caused in part by the movement of tectonic plates deep within the Earth's mantle. This movement leads to the melting of rock at high temperatures and pressures, resulting in the formation of magma beneath the Earth's surface.
Magma occurrs by rocks melting inside a volcano
Magma comes from the melting of material in the crust or upper mantle.

Melting causes an igneous rock to form into lava/magma.
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.
The melting point of diamond is sufficiently high that magma would not melt it.
The melting of metamorphic or igneous rock forms magma, which can eventually cool and solidify to form igneous rock.
