If the magma cools down fastly the crystal size is small because the crystals do not have much time to form. If They magma slows down slowly the crystal size is big because it gives the crystals time to form!
:D
Slow cooling magma will allow the growth of larger mineral crystals than quickly cooling magma.
Large. The more time the crystal has to grow, the larger it will become. When magma or lava cools slowly it allows the crystal to form large crystal grains.
When lava cools slowly large crystals will form because the crystals have had time to grow.
Larger crystals are formed as they have longer to cool.
The size of the crystals will be smaller
They have large grains, I think.

Virtually all rock contains mineral crystals of various sizes. Most volcanic rocks such as granite contain crystals of quartz and other minerals. Crystal size varies depending on the speed of cooling.
It forms a face-centered cubic crystals. Under pressure these change to hexagonal close packed (hcp) crystals.
Yes, temperature does affect crystal growth. Hot water makes the crystals grow faster because the hotter the water, the hotter the crystal solution will be which makes the molecules move faster. This movement allows water to evaporate quicker leaving particles behind to form into crystals.
Swarovski crystals are a branded type of lead crystal that is made primarily of glass and lead and may also be coated with other materials. When comparing crystals to diamonds, they are commonly referred to as a diamond simulant. Simulants may look similar to a diamond, but do not possess the same properties. A diamond is formed from carbon and has a hardness of 10 on the Mohs scale -- the hardest. Lead crystal is graded around 6-7, though both can scratch glass.
Ummm... Really? Sugar crystals... Taste great!

Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
large,well developed crystals.This is because of slow cooling process
Magma cooling beneath the surface creates intrusive igneous rocks.
Slow cooling magma below the Earth's surface forms large crystals.
you should talk about how crystals are formed and what type of crystals there are
This depends on the rapidity of the cooling. If the cooling is very slow, then one of the granites will result, identifiable by the type and presence of macro crystals - each a different mineral.If the cooling were fairly quick, then basalt polygonswill be formed ( as seen in the Giants Causeway), and these can approach a metre in dimension. These are of course, pseudo-crystals, not crystals in the mineral sense. They are the common substrate of all the rock as it spreads out from mid-ocean ridges. They are also not uncommon in volcanic outcrops.
Quick cooling lava will result in extrusive igneous rock, a type of rock classification based on its small crystals being formed from lack of time for growth during solidification.
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
The earth is composed of various types of rocks, some formed as a result of pressure while others due to cooling. Igneous rocks form when molten lava cools and solidify to form crystals.

Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
