Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.
I'm not certain exactly what mechanical weathering is but I assume it is stuff like rocks cracking due to ice expansion and rocks slowly being grinded down to dust by water currents, plant roots and grazing animals such as goats.
Weatering probably occurs faster in hot, wet climates since heat is an important factor in making chemical reactions occur (and the speed of the reactions), and water is a phenomenal solvent and chemical reactant which would also facilitate chemical reactions. Thus, it would be logical that hot, wet climates weather stuff faster than cool and dry climates, assuming all other parameters are the same.
I would guess that excessive weathering breaks down rocks and solid materials to smaller and smaller fragments it will eventually become soil/dirt.
Settlers on the great plains probably cared/knew little of soil erosion so when they settled there their farm animals and their farming techniques tore into the environment uprooting stuff that kept the dust mostly ground bound, maybe creating more dust by grinding down rocks with cows and their hooves.

It depends on the snake and if it just got done shiding or not
Answer:
You could end up doing something you'll regret? :P
Explanation:
The basic building blocks of DNA and RNA are
DNA: sugar groups, phosphate groups, and nitrogen bases; the bases are adenine, cytosine, thymine, and guanine
RNA: sugar groups, phosphate groups, and nitrogen bases; the bases are adenine, cytosine, uracil (replacement for thymine), and guanine
