Why does cooling rate affect crystal size?
As the rate of cooling increases, crystal size decreases. This means that something which cools very quickly will have smaller crystal formations, and something which cools slowly will have larger crystal formations. This is easily seen in igneous rock, which may cool at variable rates.
What factors affect the size of crystals?
Variables that control crystal growth include the amount of dissolved material, evaporation, pressure and temperature. The higher the amount of dissolved material in the water and the more pressure that is placed on the material, the bigger the crystals will grow.
How does temperature affect crystal size?
Temperature also affects the growth of crystals because “the higher the temperature, the warmer the crystal solution will be, and the faster its molecules will move. This movement allows them to evaporate more quickly, leaving particles behind to form into crystals.
In what rock types are geodes found naturally?
