Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
What type of crystal grain forms when molten rocks cool slowly?
Quartz
Why would the crystals in an intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?
Think about this: When molten rock cools slowly, bigger crystals are created.Then think about this: Intrusive rocks cool quite slowly because they are created in the earth's crust.So... Intrusive igneous rocks have bigger crystals. Molten magma in the earth's crust cools slowly making rocks like granite with big crystals.Get it? got it?GOOD!!
Which crystals most likely formed from molten material that cooled and solidified most rapidly?
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
When magma cools slowly the crystals formed are generally large?
Yes, when magma cools slowly, the atoms have more time to arrange themselves into orderly patterns, leading to the formation of larger crystals. This results in coarse-grained igneous rocks with visible crystals, such as granite.

Large crystals with a coarse crystal grain texture.

How does crystallization form?
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.

Why are crystals in basalt that formed under water smaller than those in basalt that formed on ground?
Crystals in basalt that formed underwater are smaller because they cool faster in the water, resulting in less time for the crystals to grow. On the other hand, crystals in basalt that formed on the ground have more time to grow as they cool more slowly, leading to larger crystal sizes.
When magma cools slowly the crystals formed are generally large?
Yes, when magma cools slowly, the atoms have more time to arrange themselves into orderly patterns, leading to the formation of larger crystals. This results in coarse-grained igneous rocks with visible crystals, such as granite.
Do igneous rocks have smaller crystals than those formed above the surface?
Igneous rocks formed within the earth crust have larger crystals than those formed on the surface because they have little or no interaction with atmospheric conditions and they cool very slowly.
Will larger crystals form when magma cools slowly?
yes
