Magma can be formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantle rock.
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.
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.
the chemical and physical particles
As magma rises, it carves a tube-shaped structure called a "magma conduit" or "volcanic conduit." This pathway allows the magma to move upward from the magma chamber beneath the Earth's surface towards the surface, where it can erupt as lava. The conduit can also help form various volcanic features, such as volcanoes or lava domes, depending on the composition and behavior of the magma. Over time, the solidified magma in the conduit can create a central vent or pipe structure within the volcano.
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.
by magma
As magma cools, elements combine to form minerals.
The magma has to crystalize...
The noun magma has no plural form; magma is an uncountable noun, a word for a substance.
They form underground from the cooling and solidification of magma.
magma cools to form igneous rock
Yes, granite is formed from cooling magma.

igneous rocks
When magma solidifies, it becomes igneous rock.
the mid ocean ridges cause the magma to form at a convergent plate boundary.
