Deserts where made long ago, but some may be made by the temperature and maybe sand from the beach could travel, hoped I helped!
D the region lies on the border of two tectonic plates
The answer is a. I know this because it is the only answer that is only a natural cause. Make sure your read the obvious before jumping to the conclusion that it is a hard answer. That's what i have trouble with.
The stronger the bonds between the atoms, the harder it is to break that bond, ending in a more stable state, so this is how the chemical stability of a mineral is related to the temperature at which the mineral forms.
Minerals that form at lower temperatures are chemically more stable and will decompose into clays only after higher degrees of weathering. Quartz is the only mineral that will not chemically decompose to clay. Surface water in the form of rivers and streams is one of the most powerful agents for weathering rocks.
- There are several commonly considered factors that affect the stability of a chemical compound, such as metal ion concentration, mixtures of ion concentrations, pH, buffering agents, complexation agents, and temperature
- here Chemical stability is a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical.
