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 an igneous rock with both large and small crystals?
The type of igneous rock that has large crystals surrounded by smaller crystals is not a rock but a porphyritic texture. This texture describes igneous rock that has porphyrites, or large crystals, with surrounding tiny particles, or groundmass.
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.
Rocks that contain crystals exhibit what texture?
What rocks contain crystals?
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.

How does stirring of the ice cream while freezing affect its texture?
The constant motion helps to create smaller ice crystals which will make it have a creamier texture.
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 forms crystals covalent or ionic?
gravity and texture
Large size crystals are known as phaneritic what?
A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
What kind of texture will an igneous rock have if it cooled very quickly and you can not see crystals?
The texture thus described is referred to as aphanitic texture.
What texture is igneous?
igneous is the texture of igneous rocks. The texture of igneous rocks is defined by 3 ways: a) Crystallinity- it expresses the degree of formation of crystals in an igneous rock. the texture of an igneous rock may be Holocyrstalline (Completely characterised by crystals, Hemicrystalline (partially having crystals) and holocrystalline (no crystals). b) Granularity- it is the size of the grains. it may be equigranular (when mineral grains are equal in size) or inequigranular (when mineral grains are not equal in size). c) shape of crystals- The shape of crystals may be Euhedral (When all crystals are of same shape), Subhedral (when they are partially similar in shape), Anhedral (when they are completely different in shape).
