A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.

What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
What are the difference between the sizes of the particles in granite with those in basaalt?
The crystals in granite, being intrusive in nature, will be larger than those in basalt, an extrusive igneous rock. Intrusive igneous rocks have cooled slowly from magma, extrusive rocks have cooled quickly from magma. Crystals grow larger from slow cooling magma.
What determines how large the crystals in an igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
What are fine grains of rocks?
Coarse is intrusive: the magma cooled slowly when it was formed causing big crystals... Fine is extrusive: the magma cooled quickly when it was formed causing small crystals!! your welcome mrs. bergs class:)

Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
What factor affects the size of the crystals in minerals that form from magma or lava?
If the lava cools quickly the crystals will be smaller than if it cooled slowly.
Why would granite have larger crystals than rocks formed from lava cooled above earth surface?
Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.

Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
Why do intrusive igneous rocks form big crystals?
When a molten magma is intruded into rocks it starts to cool slowly because it is insulated by the surrounding rocks, and the different minerals contained in the magma will crystallize out at different temperatures. Because it cools slowly it gives the crystals more time to grow large. A magma cooled quickly would have very small crystals.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
What are the difference between the sizes of the particles in granite with those in basaalt?
The crystals in granite, being intrusive in nature, will be larger than those in basalt, an extrusive igneous rock. Intrusive igneous rocks have cooled slowly from magma, extrusive rocks have cooled quickly from magma. Crystals grow larger from slow cooling magma.
Does magma beneath the surface cool fast?
Magma cools down about a week or so it is extremely hot about 350 degrees Fahrenheit , when it cools down it turns into crystals which are inorganic, naturally, solid, and having a atom arrangement.

Is there magma on Mars?
No. Mars has cooled so that i can no longer produce magma.
