Small crystals or possibly no crystals at all form from rapidly cooling lava.

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.
Does rapidly cooled magma or lava contain small crystals?
Yes. Rapid cooling of molten rock produces small crystals.
Intrusive igneous rock forms small crystals because it cools rapidly.?
false
What are the conditions which small and large crystals are likely to form?
Large crystals form when a rock cools from magma slowly whereas smaller crystale form when there is a slow rate of cooling
What affects the size of crystals formed from magma?
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
Will crystals be small if magma cools fast?
Yes they will
Why are mineral crystals in obsidian too small to see without a microscope?
The rock cools so rapidly from magma that crystals barely have time to form.
If a crystal cools rapidly it would be?
Not enough information. Some crystals will break if they cool rapidly, some crystals will not form correctly if the solution cools too quickly.
What crystal large or small can help identify an igneous rock as intrusive or extrusive?
As a general rule extrusive igneous rock crystals are very small, often microscopic, as the rock cools very rapidly. Conversely intrusive magma often cools so slowly that sizeable crystals can develop.
What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.

small crystals form from rapidly cooling magma?
no . they come from rapid cooling lava
Where did an igneous rock form if the rock contains large crystals?
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
True or false intrusive igneous rock forms small crystals because it cools rapidly?
False
