What texture extremely rapid cooling of lava in which no crystals form?
super fine grained rock
How Do Glassy Texture Igneous Rocks Form?
They form from the extremely rapid cooling of lava or magma. The quick cooling does not allow time for the crystallization of minerals, resulting in the formation of a natural glass.
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
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
What is the texture of granit?
Granite has a phaneritic texture. This means that it has crystals 1-10 mm. It was formed from slow cooling, viscous magma, and/or good nucleation. Crystalline. Coarse-grained. Crystals visible without magnification.
What is the resulting texture of igneous rock that is formed from extremely rapid cooling lava in which no crystals form?
The texture would be glass-like.
Is the resulting texture of extremely rapid cooling of lava in which no crystals form?
The texture is really glassy, like obsidian.
What is the resulting texture of an extremley rapid cooling of lava in which no crystals form?
They are said to have a glassy or vitreous texture.
What texture extremely rapid cooling of lava in which no crystals form?
super fine grained rock
Rapid cooling of lava in which tiny crystals form results in what kind of texture?
Rapid cooling of lava in which tiny crystals form results in a glassy texture.
Magma cooling in 2 stages slow and then fast what is the resulting texture?
The resultant rock would have a porphyritic texture; large crystals (usually feldspars) scattered among small crystal grains.

What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
What is the result texture of rapid cooling of lava in which tiny crystals form?
Fine-grained
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.
Does slow cooling of molten rock lead to formations of large crystals?
Slow cooling of molten rock leads to rocks with an phaneritic texture; one with larger, visible mineral crystals.
Do extrustive rocks have small crystals?
Yes, extrusive rocks are rocks that cool rapidly on the surface. Because of the rapid cooling the phenocrysts have little time to grow. Thus resulting in a type of aphanitic texture. Large phenocrysts can be referred to as porphyritic and it is has crystals that are over a certain diameter.
