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.
Which igneous rock has larger crystal one that cooled slowly or one that cooled quickly?

Is it true as magma cools it's atoms tend to move away from each other?
The slower the rate of cooling the larger the size of the crystals that can develop.
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.
Why do some igneous rocks have larger crystals than others?
The size of the crystals depend on the time it took the rock to cool. Slow cooling rocks have larger crystals because they had a longer time to grow their crystals. For example Basalt is an volcanic extrusive igneous rock that forms from rapid cooling of the magma and are usually located near the surface or on the ocean floor, it has finer crystals not visible by the naked eye. Granite is an intrusive igneous rock that forms from slow cooling of the magma within the earth crust, it has larger crystals.
What is the difference in appearance between igneous rocks that have cooled slowly and igneous rocks that have cooled quickly?
Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.
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.
What does the presence of large crystals tell you about the rock's formation?
It cooled slowly, forming larger crystals.

What does crystal size mean?
In igneous rocks, large crystals mean that the rock cooled more slowly. Smaller crystals mean that the rock cooled more quickly.
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.
Why does Granite take much longer to form than Basalt?
hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite
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.
Do igneous rocks have large crystals?
Yes, they can. Extrusive igneous rocks, which form outside the Earth's surface, often contain small or no crystals, because they cool quickly and the particles in the lava do not have much time to arrange themselves. Intrusive rocks, which form inside the Earth, generally have large crystals because they cool slowly. Granite is an example of an igneous rock with large crystals.
The size of the mineral crystals found in an igneous rock is directly related to the?
the rate melted rock cools.
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.
