The slower the rate of cooling the larger the size of the crystals that can develop.
Volcanism
Mineral present in molten magma.
The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.
A vesicular igneous texture generally indicates rapid cooling.
Slow cooling of molten rock leads to rocks with an phaneritic texture; one with larger, visible mineral crystals.
Molten rock contains liquified minerals, some solid mineral grains, and dissolved gasses.
Molten rock contains liquified minerals, some solid mineral grains, and dissolved gasses.
molten slag mainly contain CaO, MgO, FeO, SiO2 etc.
Molten material below ground is called magma, and molten material above ground is called lava.
the asthenosphere and the lithosphere contain molten material.

The molten material that reaches earth's surface is lava :)
When under ground, molten volcanic material is known as magma, but once erupted, it is called lava.
Igneous (formed from molten rock), metamorphic (formed from metamorphism of preexisting rock), sedimentary (formed from cementation or compaction of sediments, mineral precipitation, or organic material).
Molten rock that is underground is called magma.
