Is a volcano physical or chemical?
No. Although chemical changes can occur as part of the eruption, it is for the most part a physical process.
How does magma form at a subduction zone?
it is a chemical interaction started by the water the subducted plate brings down with it which causes melting and forms magma which creates volcanoes
Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.
What are the characteristics of magma?
the chemical properties of magma are the chemical properties of whatever it contains but only if it is broken down - otherwise it is really, really hot melted rock.
What process is required for minerals to crystallize from magma?
The process is cooling. When magma cools slowly, large well-define crystals form.
What is the name of the process that turns hot molten rock into igneous?
Melting! Igneous rock is formed by melting, chemical and physical changes within the melt (magma) then solidifying.
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
When do ores form in the process of contact metamorphism?
When magma changes the composition of existing rock.

Why is magma not a mineral?
Magma is not a mineral becauseIt is liquid.It does not have a definite chemical composition.
What is assimilation in geology?
I am guessing you are talking with regard to magmatic differentiation during the eruption process? If so assimilation is simply the chemical change in the magma due to the magma melting other rock types that make up the walls of the conduit. This process often explains "abnormal" mineral compositions.
Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.

The process is cooling. When magma cools slowly, large well-define crystals form.
What is the driving force of plate tectonics'?
That force is caused by the convection currents in the magma below the plates.
What is the layer of the earth that takes the changes of a earthquakes?
magma
