. As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.

The size of crystals decreases as the cooling increases. This is called an inverse relationship.
Why do most mineral samples not visibly show their crystal form?
because of quick cooling igneous rocks .
What do large crystal grains in an igneous rock indicate?
A vesicular igneous texture generally indicates rapid cooling.
What is the best evidence for determining the cooling rate of an igneous rock during its solidification is provided by what?
the crystal size of its minerals

What relative cooling rates of igneous intrusive rocks can be estimated by comparing rocks?
Crystal
What are three things crystal size dependent on?
Primarily the cooling rate of the mineral compound.The faster the rate cooling smaller the crystal size of the mineral.Consequently, large crystal specimins are derived from igneous bodies with a very slow rate of cooling.

What do large crystal grains in an igneous rock indicate?
A vesicular igneous texture generally indicates rapid cooling.
Why are extrusive igneous rocks not coarse grained?
Because the rapid cooling does not allow much time for crystal growth.

What does crystal size indicate?
Crystal size in igneous rocks is generally a marker for how long magma or lava took to cool and solidify. Larger crystal size is indicative of slow cooling.
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
