It can. As lava cools, some of it starts to cool while the rest remains liquid. If it erupts at this point it will result in a porphyritic rock.

When magma cools too fast what happens to the size of the crystals?

When magma cools fast, crystals are small.Less time to form crsytalsWhen magma cools slow, crystals are large.More time to form crystalsWhen magma cools very fast, crystals do not form; nothing.Very less time to formWhen magma cools very slow, large crystals form; a LOT.A lot more time to form


What type of rock forms when tiny crystals in magma form?

When tiny crystals form in magma, they create an igneous rock known as "intrusive" or "plutonic" rock. This occurs when magma cools slowly beneath the Earth's surface, allowing the crystals to grow larger, such as in granite. If the magma cools quickly on the surface, it forms "extrusive" or "volcanic" rock, like basalt, where the crystals are much smaller.


Will crystals be small if magma cools fast?

Yes they will


Why is magma a slushy mixture of crystals and molten rock?

Slush is a word given to describe half melting water ice where crystals of ice are present together with a little liquid water. If one had a magma made of crystals in present together with liquid rock - this could be described as a "slushy" mix BUT please note a normal Magma will be entirely liquid until it moves to environment where it begins to cool (at which point crystals will start to form in it) - magma is ONLY a slushy mix for a short time - just before it solidifies.


What below the Earths's surface cools and hardens to form mineral crystals?

Magma beneath the Earth's surface cools and solidifies to form mineral crystals. This process takes place over long periods of time, allowing different types of crystals to form depending on the minerals present in the magma.

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

Slow cooling of hot magma lead to the formation of what crystals?

large crystals


Are crystals denser than magma?

Yes.


How would crystals formed early from magma be larger and better formed than those formed later?

The crystals formed early by magma would not be deficient of certain elements. Once these elements are used up, they are not available in the magma to form later crystals.

Can minerals from from the cooling of magma?

Yes. When magma cools and solidifies, mineral crystals are formed.


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.


Can Minerals form from the cooling of magma.?

Yes. When magma cools and solidifies, mineral crystals are formed.
