Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
Actually it is.
It prevents the two populations from interbreeding. :) -Apex-
it prevents gene flow between populations
Isolation such as geological can cause speciation because if one species where divided into two because of geological reasons, they're likely to change their behaviors and physical appearances to match that region.
Divergent speciation refers to the rise of a new species when organisms that can interbreed and reproduce fertile offspring get separated. Separation can be due to geographical barriers like mountains and lakes.
factors that cause weathering are erosion and water

One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
genetic factors
what is the factors that may cause a decrease in the demand of ice-cream
1) Hybridization 2) Differential resource exploitation 3) Sexual selection 4) Allopolyploidy Basically all of the above.
