alright, if it cools quickly it will form pumice because of the bubbles in it.
if it cools slowly, it will form obsidian.

How the minerals formed by magma?
Magma is molten rock, as the magma cools the minerals crystallize out of it, the slower it cools, the larger the crystals.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
What cools quickly on the earth's surface?
it would be lava , magma is in the ground and flows on earths surface and cools to lava
What process is required for minerals to crystallize to magma?
Magma rises when it is being pushed or heated from below.
What type of rock is formed when magma undergoes crystallization above ground?
Extrusive igneous rock is formed from the crystallization of magma (lava) above ground.
How the minerals formed by magma?
Magma is molten rock, as the magma cools the minerals crystallize out of it, the slower it cools, the larger the crystals.
What is the simplified pattern that illustrates the order in which minerals crystallize from cooling magma?
when magma cools fast you get smaller crystals when it cools slow you get large crystals its very simple
When magma cools minerals with higher melting points will?
Minerals with higher melting points will crystallize.
What process is required for minerals to crystallize from magma?
The process is cooling. When magma cools slowly, large well-define crystals form.
How and where are igneous rocks formed?
Igneous rocks are formed on and below the surface of the Earth when lava or magma cools enough to crystallize.
What is the first minerals to form when magma cools that are rich in iron calcium and magnesium?
Olivine is the first mineral to crystallize as the mineral first to crystallize is the last to melt.
What causes different crystal shapes?
Crystals are made from molten magma that cools causing silicate minerals to crystallize. The different crystal shapes form differently as the magma cools at different rates.
Why do rocks form?
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
What is intrusive?
Intrusive activity is when magma in the mantle or crust starts to cool and crystallize. Igneous rock forms from the crystallization.
What is the name of the rock that cools above surface?
magma
How is ignius rock formed?
it is formed either underground or above ground. it is formed underground when hot magma is trapped and cools slowly, when it has cooled down it has then become igneous rock but on top of the ground the lava cools much quicker then what it does below the ground
