How does the rate of cooling affect crystal growth in igneous rock?

∙ 9y ago
The most common effect is that more and smaller crystals form than would be formed with slow cooling of the same mass of the same crystalizable material, and the incidence of crystal defects is higher because the rapidity of crystal formation does not permit the correction of initially formed defects by interchange of atoms or other crystal forming units between the liquid and solid phases that can occur during slow crystallization.

∙ 10y agoThe rate of crystallization is impacted by a number of factors. Before crystallization, super saturation is necessary. Heat will speed up this process by assisting in dissolving solids within the liquid base. Initial agitation will speed up this process however after crystals have started forming, agitation will greatly disrupt the process.

What do extrusive igneous rocks look like?
The particle size (grain size--crystal size) in igneous rock is largely dependent on the amount of time spent cooling and solidifying from molten rock. If cooled quickly, crystals will have little time to grow. Slow cooling allows time for larger crystal growth.
What causes large crystals in intrusive igneous rocks?
Intrusive igneous rock is formed underground by the slow cooling of magma. With the insulating and heat retention effects of an underground environment, ions are free to move about the fluid magma and join onto growing mineral crystals. In a quick cooling environment, crystallization occurs rapidly, with little time for crystal growth.
How does the amount of ethanol affect crystal growth?
it doesnt
How does temperature affect the growth of igneous rock crystals?
the lower the temperture the better the crystals the higher the temperture the wrosts the crystals
Where did an igneous rock form if the rock contains large crystals?
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
Why are extrusive igneous rocks not coarse grained?
Because the rapid cooling does not allow much time for crystal growth.
Does cooling rate affect solubility?
slower rates of cooling will create larger crystals, rapid cooling allows little time for element accumulation in the crystal, therefore, the crystals created will be smaller. larger, visible crystals in igneous rock indicate that the magma was slow cooling, usually at depth. much smaller crystals in igneous rock indicate rapid cooling of lava, usually at or near the surface. crystals in igneous rock will grow larger and have more to accumulate material for their growth the more they have at their crystallization temperature.

What is the difference in crystal growth between intrusive and extrusive igneous rock?
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.

Can the color of light affect crystal growth?
Yes it may
What is the affect of temperature on crystal growth?
Temperature doesn't really affect the crystal size; the rate of cooling is the major factor. The faster the mineral, rock, etc. (whatever has the crystals) cools, the smaller the crystals- the slower the larger. If you were "growing" crystals with a set, the warmer the temperature generally means the larger the crystals.
What are the factors that affect crystal growth in cooling rocks?
Temperature, pressure, availability of source material, and space available for formation all affect the crystallization process of minerals.
How can you tell that gabbro crystalized deeper underground than basalt did?
Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.
