When lava cools very suddenly (a process known as quenching), it creates a glassy, or hyaline, texture. This sudden cooling also creates very small, often microscopic, crystals in the rock. The most well-known example of a glassy textured igneous rock is obsidian.

What is the texture of an igneous rock when it was formed from cooling maga deep beneath the earth?
It is likely to have a coarse-grained texture.
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.
What do large crystal grains in an igneous rock indicate?
A vesicular igneous texture generally indicates rapid cooling.
How does the rate of cooling affect the type of igneous rock formed?
The rate at which the rock cool from the liquid magma determines their texture
What 2 igneous are formed by fast cooling lava?
Rock and igneous plants

Is igneous rock that formed from cooling lava fined-grained?
yes because of the fast cooling rate
What 2 igneous are formed by fast cooling lava?
Rock and igneous plants
What is the name of the crystal grain that is formed when molten rock cools slowly?
The texture of the rock product of slow cooling magma is referred to as coarse grained.
When a rock is formed by the process of cooling liquid rock it is called a?
The rock formed by cooling a liquid rock after processing is called a crystal.
What is the rock formed from the cooling and solidification of magma beneath the surface of the earth?
Its a igneous rock whenit is made formed by magma.
An intrusive igneous rock will have what type of texture?
Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
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 determine the texture of igneous Rock?
The texture is mostly determined by the time spent in cooling from magma or lava. The quicker the transition from molten to solid, the finer the texture.
