What can cause granite to break down into soil over time? A.Rain and Wind,B.Soil Deposition,C.heat from magma,or D.pressure unde
Westkost [7]

Answer:

Rain and wind will cause granite to break down and form soil over time.

Explanation:

Granite is an igneous rock, and it is one of the hardest rocks for that matter. Being an igneous and very hard rock, granite is not easy to break down and it takes a very long time, tens of millions of years in fact, and that is only if it is on the surface and exposed to the outside elements. Basically, this rock needs a very long period of time to get transformed into soil, but like any other rock it is not unbreakable and eventually, it starts to break up.

Two things that will have a big influence on the breaking up of granite would be rain and wind. The rain will cause chemical weathering while the wind will cause mechanical weathering. They will manage to gradually break up very small, fine, pieces of granite, and if they are supported by suitable climatic conditions and a lot of vegetation the process will speed up. Once the granite is broken apart and what is left of it is fine sediments, by mixing with the biomass it will form a soil.

How does region's elevation impacts it's climate and economy
Arte-miy333 [17]

Answer:

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
