Small crystals or possibly no crystals at all form from rapidly cooling lava.
Yes. But larger crystals occur slower and under the crust.
no . they come from rapid cooling lava
Yes niq
True
Yes.
Your answer is true i hope this helps!!!!!
Yes they will
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.
Yes. Rapid cooling of molten rock produces small crystals.
false
When molten magma cools and crystallizes, it becomes a hard rock called igneous rock. Different magmas have different compositions and so produce different igneous rocks. If the magma cools beneath the earth's surface, it cools slowly. Rocks formed like this are called intrusive rocks, and have large crystals, e.g. granite, gabbro, dolerite. If magma comes to the surface (in a volcanic eruption) it cools rapidly. Rocks formed like this are called extrusive rocks, and they have small crystals, e.g. basalt, obsidian, pumice. Igneous rocks have interlocking mineral crystals. The crystals are arranged randomly throughout the rock. Igneous rocks are mostly non-porous.
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
Yes they will
The rock cools so rapidly from magma that crystals barely have time to form.
Not enough information. Some crystals will break if they cool rapidly, some crystals will not form correctly if the solution cools too quickly.
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.
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.

no . they come from rapid cooling lava
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
