Which type of rock that will have small crystals if cooled rapidly?

== == The crystals will be small or may not form at all. Fast cooling magma produces small crystals. Slow cooling magma produces larger crystals. The longer a mineral has to form at its crystal growing temperature range, the larger the crystals will be.

e.g. basalt, pumice*, obsidian.
*Note that pumice is vesicular.

Does rapidly cooled magma or lava contain small crystals?
Yes. Rapid cooling of molten rock produces small crystals.
What do small crystals in an igneous rock mean?
The size of the crystals in an igneous rock tells us how fast the magma cooled.
What igneous rock cooled the most rapidly?
Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).
Intrusive igneous rock forms small crystals because it cools rapidly.?
false
The texture of an igneous rock depends on the size and shape of its?
The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
Does rapidly cooled magma or lava contain small crystals?
Yes. Rapid cooling of molten rock produces small crystals.
Why do andesite have small crystals?
Andesite is an Igneous Rock. It has small crystals because it cooled quickly d;D

Does rapidly cooloed rock contain small crystals?
YES.
What type of rock had no visible crystals as result of rapid cooling?
Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.

Intrusive igneous rock forms small crystals because it cools rapidly.?
false
The size of the mineral crystals found in an igneous rock is directly related to the?
the rate melted rock cools.
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 determines how large the crystals in the igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
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.
True or false intrusive igneous rock forms small crystals because it cools rapidly?
False
