When magma cools too fast what happens to the size of the crystals?
When magma cools fast, crystals are small.Less time to form crsytalsWhen magma cools slow, crystals are large.More time to form crystalsWhen magma cools very fast, crystals do not form; nothing.Very less time to formWhen magma cools very slow, large crystals form; a LOT.A lot more time to form
What type of solution is most likely to form crystals as it cools?
A supersaturated solution is most likely to form crystals as it cools.
What below the Earths's surface cools and hardens to form mineral crystals?
Molten magma cools and hardens to form mineral crystals.
Would quartz or plagioclase be more likely to form a well shaped crystal in an igneous rock?
A well-shaped crystal in an igneous rock needs room and time to grow. So, minerals with high melting points form well shaped crystals while ones with lower melting points don't because there isn't as much time for them to form. Quartz crystallizes at a lower temperature than plagioclase so plagioclase is more likely to form well-shaped crystals.
When lava cools quickly large crystal form?
No. Small crystals form.

What affects the size of crystals formed from magma?
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
If a crystal cools rapidly it would be?
Not enough information. Some crystals will break if they cool rapidly, some crystals will not form correctly if the solution cools too quickly.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
What does lava that cools quickly form?
fast cooling lava -small crystals or no crystals
What lava that cools quickly form?
fast cooling lava -small crystals or no crystals
Does lava cool quickly and form minerals with small crystals?
Yes. The faster lava cools, the less time crystals have to form. If the lava cools slowly and has a low viscosity, atoms are able to move around more and form larger crystals.
Will larger crystals form when magma cools slowly?
yes
Do large crystals form when magma cools?
it is more than it
