Magma is the term applied to molten rock beneath the surface of the earth. It is formed when hot (very hot) rocks experience a drop in surrounding pressure, or when subducted wet lithosphere is introduced into the mantle. When it "breaks out" onto the surface of the earth, we call it lava. A link can be found below.

What is the earth magma?
it's lava but in it's liquid form. A common misconception between magma and lava is lava is solid and magma is liquid hot.
What does magma with high silica content form?
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
What are the factors that might cause magma to form a laccolith instead of a sill?
the chemical and physical particles
What is the only kind of rock that can form directly from magma?
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
Mica and feldspar form from slowly cooling magma that solidifies into a what?
intrusive igneous rock eg Granite
How does magma form geological features?
by magma
How are mineral formed by crystallization from magma?
As magma cools, elements combine to form minerals.
What has to happen to magma for glass to form?
The magma has to crystalize...
Are pyroclasts formed by basaltic magma or andesitic magma?
Pyroclasts can be formed of any type of magma. However, they are more likely to form with andesitic than basaltic magma. Rhyolitic magma will also readily form pyroclasts.
What is the plural of magma?
The noun magma has no plural form; magma is an uncountable noun, a word for a substance.
Where do intrusives rocks form?
They form underground from the cooling and solidification of magma.
What does magma pushed into a thick sill form?
magma pushed into a thick sill can form what
Does granite form from magma?
Yes, granite is formed from cooling magma.
Does granite form magma?
