Can lava make glass?
Volcanic glass forms when molten material cools too quickly for crystals to form. The small size of volcanic ash particles ensures that the cool quickly.
Why do some rocks have both small and large crystals?
It depends how slow/fast it cools into a rock. The slower it cools, the larger the crystals. The faster it cools, the smaller the crystals. It can also have no crystals. Let's say lava shot itself into the water. It cools so fast it might not have crystals
Does basalt have small crystals or big?
Since basalt is extrusive it cools quickly and forms small crystals.
Will crystals be small if magma cools fast?
Yes they will
What is a type of crystal grain that forms when rock cools Slowly?
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.

Andesite has small crystals because?
Andesite has small crystals because it cools quickly.

Is rhis sentence true or false lava cools quicklyand forms minerals with small crystals?
It is true that lava cools quickly and forms minerals with small crystals.
What does lava that cools quickly form?
fast cooling lava -small crystals or no crystals
What lava that cools quickly form?
fast cooling lava -small crystals or no crystals
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
What are the size of granite crystals?
Small, because it cools slowly
What size are the crystals in an igneous rock that cools quickly?
Small
