why each mineral has its own definite crystalline pattern

They grow in different settings, so they have different patterns and shapes that they grow into.

 list each of the 5 criteria for a substance to qualify as a mineral

Naturally occurring, Solid substance, definite chemical composition, orderly crystalline structure, and inorganic

difference between rock that forms from a hydrothermal environment and rock that forms in a sedimentary environment

One that forms in a hydrothermal environment form from superheated water, and dissolves ions. As the ions reach the surface they cool and form minerals. In a sedimentary environment, water evaporates and ions fall out of solution with the water to form minerals

If a mineral forms in an igneous environment, what does this mean

It means they are molten rock, made from magma
