Water molecules in lakes and the atmosphere and many miles
apart from each other. What processes allow water molecules
to move between these areas despite so much distance
between them?

Evaporation is the process which allow water molecules to move between lakes and the atmosphere.

Explanation:

Evaporation is a process in which water which is present in liquid form in lakes and ocean evaporated in the form of water vapours. These vapours goes upward and form clouds which moves toward hilly areas with the help of wind. The water present in the clouds come back to the land in the form of rainfall and snowfall. This water flows through the streams and collected in the rivers again and repeat this process.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
