== == The crystals will be small or may not form at all. Fast cooling magma produces small crystals. Slow cooling magma produces larger crystals. The longer a mineral has to form at its crystal growing temperature range, the larger the crystals will be.

Does rapidly cooled magma or lava contain small crystals?

Yes, rapidly cooled magma or lava typically results in the formation of small or no crystals due to the limited time available for crystal growth. This leads to the development of fine-grained or glassy textures in the rock.


Why do andesite have small crystals?

Andesite is an Igneous Rock. It has small crystals because it cooled quickly d;D


What do small crystals in an igneous rock mean?

The size of the crystals in an igneous rock tells us how fast the magma cooled.


Does rapidly cooloed rock contain small crystals?

YES.


What type of rock had no visible crystals as result of rapid cooling?

Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.


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


Intrusive igneous rock forms small crystals because it cools rapidly.?

false


What igneous rock cooled the most rapidly?

Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).


A mineral specimen has very small crystals what is the best explanation for how this happened?

The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.


Do igneous rocks have large crystals?

It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.


What does the presence of tiny crystals in a piece of igneous rock tell you about it?

The presence of tiny crystals in igneous rock indicates that the rock cooled quickly, resulting in the formation of small crystals. This suggests that the rock likely formed near or at the Earth's surface, like in a volcanic eruption. Rocks with larger crystals usually form deeper underground where cooling is slower.


What determines how large the crystals in the igneous rock will be?

How fast the magma or lava cooled. How fast the rock cooled
