Can Small amounts of water can lower partial melting temperatures in silicate rocks?
The addition of water can lower partial melting temperatures in silicate rocks.
Basalt is generated by?
partial melting of mantle rocks
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.
Can Small amounts of water lower partial melting temperatures in silicate rocks?

Most basaltic magmas are believed to form by partial melting of granite in the lower crust and upper mantle?
This statement would be considered incorrect. Basaltic magmas originate from the melting of mantle rock or oceanic crust.
Why is the earth full of lava?
The Earth is not full of lava. The majority of the earth is solid and small amounts of lava are produced by partial melting of this solid.
Can Small amounts of water can lower partial melting temperatures in silicate rocks?
The addition of water can lower partial melting temperatures in silicate rocks.
Basalt is generated by?
partial melting of mantle rocks
Would pressure play a role in partial melting?
In so far as pressure affects the melting point of substances, the answer is yes.
Which process is the key concept behind smelting metals from ores?
Partial melting
What is thought to form by partial melting and in situ crystallization of the melted portion?
migmatite
What is responsible for the partial melting of peridotite beneth the mid-ocean ridges?
An increase in pressure.
Why are volcanic chains associated with convergent boundaries?
partial melting occurs due to subduction.
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.
What does most Most magma form from?
Magma is the result of partial melting of crustal rocks. It is a eutectic melt product.
What is the name of semi-molten rock?
we can call it an igneous rock because it coming from partial melting of preexisting rocks
