The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Chemical Weathering<span> results from chemical reactions between minerals and Water. Water dissolves calcite </span>more<span> readily than it </span>does<span> feldspar, so calcite is considered a chemical reaction with water.

Fossil fuel power burn carbon fuels such a coil,oil or gas to generate that drives large turbines that produces electricity by burning carbon fuel they produce large amount carbon dioxide.
