Why are volcanic chains associated with convergent boundaries?
partial melting occurs due to subduction.
What is the name of semi-molten rock?
we can call it an igneous rock because it coming from partial melting of preexisting rocks
What processes causes the formation of magma?
Partial melting of rock produces a magma. When rock is heated (by the heat emanating from the Earth's core) it DOES NOT all melt at the same time. In the same way that adding antifreeze to water prevent it freezing, certain mixtures of elements (from the minerals making the rock) melt out first to form a liquid. These melts flow together from between the mineral grains to make the magma. This process of partial melting produces PARTICULAR magma compositions depending on the make up of the source rocks which is why magmas have definite chemistries and are different in different places. Basalts are made from partial melts of the upper mantle, Andesites are magmas made from partial melts of the crust etc.
Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.
What can texture tell us about the history of the rock and melt?
The initial composition of the magma is dictated by the composition of the source rock and the degree of partial melting.
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 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 are the causes of partial deafness?
what are the cause of partial deafness
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 are the causes of partial deaftness?
Some possible causes of partial deafness include prolonged exposure to loud or constant noise, disease and injury.
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 causes a soild to a liquid?
By melting
What does melting do to a igneous rock?
Melting causes an igneous rock to form into lava/magma.
