What Are 3 Ways Crystals Are Formed

What are the three ways minerals are formed?

I don't know of any particular websites, but here in a nutshell is what all that means. Precipitation from a solution occurs when the chemicals that will form a mineral are in solution (of water, usually). When the water begins to evaporate the concentration of the chemicals increases, until there isn't enough water to hold them all in solution. At that point the chemicals bond to one another in a regular manner, and mineral crystals are formed. To demonstrate this all you need do is dissolve common salt in hot water, until no more dissolves. Then take some of the hot, salty water away and let it cool slowly. As it cools crystals of salt will re-crystallize. Solidification of a melt is essentially the same process, except here there are many different chemicals involved, and each one forms at a different temperature. As one mineral forms, the concentration of various chemicals in the melt is altered, and that mineral no longer can form, but others begin, and the process continues until the melt solidifies. The minerals in such an Igneous Rock are formed at a particular temperature, and so the minerals in the rock can be used to determine the original melt composition and temperature. During the course of solidification of a melt, rock metamorphism, and even diagenesis (low temperature alteration of minerals and rocks) ions present in fluids surrounding the minerals may be "accepted" by ions already in the minerals, and change the chemical makeup, thus making a new mineral. This is solid state diffusion, because the minerals do not dissolve or melt. Solid state diffusion can also take place only due to high temperatures or pressure (or both), without the need of fluids. Two ways in which minerals can form were not mentioned: recrystallization and dehydration. Some minerals are unstable. The mineral aragonite has the same chemical composition as the mineral calcite, but has a different crystalline structure (so they are separate minerals). After it is formed it begins to recrystallize to calcite, basically at surface temperatures and pressures, so there is very little aragonite in older rocks, mostly calcite. An example of dehydration is gypsum and anhydrite. Gypsum is hydrous calcium sulfate. When it loses it's water molecules due to heat during burial, it becomes the mineral anhydrite (which is anhydrous calcium sulfate). They are different minerals.

Why did ice crystals form in this way?

Coolest thing just happened. My fridge/freezer unit is on the blink. Repairman will be here Thurs, but in the meantime i have my fridge stuff in the freezer (it's keeping things about 38 F or 3.33 C).

Anyway, i put my diet soda in the freezer. When i popped the tab, it was liquid. When i poured it into a glass, it formed these very cool, fluffy ice crystals. Kind of like a slurpee but the ice was "softer" (don't know how else to describe it).

Why did this happen? Why was it liquid and then when poured created ice? Thanks!

What are three ways clouds can form even in stable air.?

1. Ground fog "lifting" into a low stratus cloud layer. This is caused by the air just above the ground warming with time as the fog will act like a blanket. The fog will insulate the heat energy that is radiating from the ground. With time, this heating will clear the lowest layer of this fog and then you will be left with a low stratus cloud deck.

2, Fog forming over cold water will move inland with the onshore breeze.

3, Wind blowing up a hill or mountain slope will cool and condense. In this case, clouds are forming due to terrain forcing.

4. A layer of mid level clouds form due to over running between two air masses with different density.

5. High cirrus clouds invading the sky. These clouds are usually thin and are the result of very cold temperatures high in the atmosphere causing the formation of a layer of small ice crystals.
