Are crystal always formed by ions?
No, not all crystals are formed by ions. Some crystals are formed by covalent bonds, where atoms share electrons, rather than by the attraction of ions. Additionally, some crystals can be formed by metallic bonds, where electrons are delocalized among a lattice of metal atoms.
Are sedimentary rocks formed because of water evaporating and leaving crystals behind?
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
What is a type of crystal grain that forms when rock cools Slowly?
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?
how long they stayed in the volcano; how much time the crystals had to form
Why do some igneous rocks have larger crystals than others?
The size of the crystals depend on the time it took the rock to cool. Slow cooling rocks have larger crystals because they had a longer time to grow their crystals. For example Basalt is an volcanic extrusive igneous rock that forms from rapid cooling of the magma and are usually located near the surface or on the ocean floor, it has finer crystals not visible by the naked eye. Granite is an intrusive igneous rock that forms from slow cooling of the magma within the earth crust, it has larger crystals.
Are some crystals are formed from minerals dissolved in liquids?
Yes, in fact that's how a lot of crystals are formed.
Does tuff have crystals?
In some cases it does contain crystals that formed prior to the eruption.
Are crystals formed by volcanoes?
Some are, not others.

How do you suppose a halite is crystals formed?
Halite crystals are formed by evaporation from solution. To try this at home, boil some water, add salt until no more will dissolve, and let cool. Crystal growing is fun!
What is salol?
I think that it is some sort of liquid. We used it in science class to grow crystals. * SALOL is phenyl salicylate, which comes as a white crystal and then is melted down and cooled at varying temperatures and conditions to form different size crystals.
Why are some clouds built up of water droplets while others are made up of ice crystals?
For ease of explanation we may say that it all depends on the height of the clouds. Cirrus clouds are high and thin and made entirely of ice crystals forming above 20,000 feet. Low clouds are formed when water vapor turns back into liquid water drops, called condensation. The more the cloud rises the cooler it becomes until ice crystals are formed

How do minerals form on Earth and how do humans benefit from them?
i am not absolutely positive but i do know that some crystals can be melted down to use in electronics as a matter of fact the computer you are looking on right now may have crystal in it crystals add taste to food as weird as that sounds think of salt
Do all crystals form in caves?
No because i made some in school last year and it all depends on the climate, and how it is formed/made.
What is the relationship between cooling time igneous rocks and the size of its crystals?
Plutonic rocks are intrusive (they solidify before they reach the surface) and have larger crystals because the crystals have had a longer time to accumulate in the heat under the surface. Volcanic rocks are extrusive (they solidify on or near the surface) and have smaller crystals because the element has less time to accumulate when they cool quickly.
