What else can I help you with?
What are the conditions which small and large crystals are likely to form?
Small crystals are likely to form when the solution cools quickly or when there are impurities present that inhibit crystal growth. Large crystals are likely to form when the solution is allowed to cool slowly or when there is a high concentration of solute in the solution.
Why does pumice have no crystal structure?
Pumice is made of glass. Glass forms when molten rock cools too quickly for crystals to form.
Do large crystals form when magma cools quickly?
large ones
If lava cools to quickly that ions don't have time to arrange themselves into crystals will form what?
glassy texture, hope this helps :)
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.
Type or crystal grain that form when molten rock cools quickly?
Fine crystal grain.
Type of crystal grain that form when molten rock cools quickly?
Small crystal grains form when molten rock cools quickly. In an extrusive igneous rock, it's referred to as aphanitic texture.
If the lava cools quickly the crystal are what?
If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.
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.
Whey are pumice crystal's small?
Pumice doesn't have crystals at all, as it cools too quickly for them to form.
What are the conditions which small and large crystals are likely to form?
Small crystals are likely to form when the solution cools quickly or when there are impurities present that inhibit crystal growth. Large crystals are likely to form when the solution is allowed to cool slowly or when there is a high concentration of solute in the solution.
Large crystals with well-formed crystal faces tend to form when?
Large crystals with well-formed crystal faces tend to form when the mineral is given enough time to grow undisturbed in a stable environment with plenty of space and nutrients. The slower the cooling or solidification process, the larger and more well-formed the crystals can grow.
How does the cooling rte of rocks affect the crystal size?
If rock cools quickly it does not have time to form large crystals and so it forms small ones. At slower cooling rates there is time to form larger crystals.
What is the type of crystal grain that forms when molten rock cools quickly?
Small crystal grains form from rapid cooling of magma resulting in an aphanitic rock texture.
Why does pumice have no crystal structure?
Pumice is made of glass. Glass forms when molten rock cools too quickly for crystals to form.
What type of crystals is formed from slow cooling?
Crystals formed from slow cooling typically have larger crystal sizes due to more time for the atoms to arrange in an ordered structure. This results in minerals with well-defined crystal faces and clearer textures, as seen in intrusive igneous rocks like granite and gabbro.
Do large crystals form when magma cools quickly?
large ones
