The most evident one is Land mass separation like continental drift, or an island.

You just have to think of events that could cause separation of members of a population. Geographic separation is obvious, but what about temporal variation, or diet variation, ie part of the population eats plant A while others eat plant B.

Allopatric speciation and parapatric speciation. Also peripatric speciation. We will not mention sympatric speciation in this discussion. Google the first three for complete explanations.

A catastrophic event separating the two.
I never saw any kind of "speciation" occuring.

Migration for food is the number one factor, floods, island isolation for example chimps and bonobos
