How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
Rocks that have crystals?
Igneous rocks
Why are lava flows finer grained than intrusive igneous rocks?
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.

What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.

What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.

What is a type of igneous rock that forms visible crystals?
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
How is Any rock solidified from molten material is classified as?
Any rock created by the cooling of magma or molten material is classified as an igneous rock. These rocks can either be cooled in the earth or on the earths surface. Rocks cooled inside the earth are called intrusive igneous rocks, and have large crystals. Rocks cooled on the earth's surface are called extrusive igneous rocks. These rocks, due to faster cooling times, have very very tiny crystals.
Where would you expect to find an igneous rock with small crystals?
you would find igneous rocks with small crystals at the bottom of the volcano, this is because when the rocks crack. It brakes apart into igneous rocks
The formation of igneous rocks is powered by?
the cooling and solidification of molten magma or lava. This process occurs either underneath the Earth's surface, resulting in intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks. The rate of cooling determines the texture and crystal size of the rock, with slower cooling allowing for larger crystals to form.
