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!

What type of rock is a crystal rock?
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.
What type of crystalline solid does xenon form?
It forms a face-centered cubic crystals. Under pressure these change to hexagonal close packed (hcp) crystals.
What effect do temperature changes have on 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.
What is the difference between swarovski crystals and diamonds?
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.
What type of crystal does sugar form?
Ummm... Really? Sugar crystals... Taste great!
What type of crystals is formed from fast cooling?
blue crystal
What type of crystals form when magma cools very slowly deep beneath the Earth's surface?
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
What type of crystals form in intrusive rocks?
large,well developed crystals.This is because of slow cooling process
What rock type is formed from the slow cooling of magma under the earths surface?
Magma cooling beneath the surface creates intrusive igneous rocks.
When magma cools slowly below Earth's surface it forms rocks with what type of crystals?
Slow cooling magma below the Earth's surface forms large crystals.
What do you do on a science fair about crystals?
you should talk about how crystals are formed and what type of crystals there are
What kind of ingeous rock would it be if magma crystallizes before it reaches earths surface?
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.
What does quick cooling of ejected lava result in?
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.
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
What type of rocks form due to cooling?
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.
What type of cloud is is formed by ice crystals?
Cirrus clouds
An intrusive igneous rock will have what type of texture?
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.
