Asmall island in the pacific ocean has many different types of geography, including a steep mountain in the middle. name two reasons this island would have a high rate of speciation.

A small island in the Pacific with a high rate of speciation has multiple reasons for that, but the two reasons that will stick out the most are:

- Volcanic activity
  The volcanic activity will be the cause for the existence of the island for starters. It will shape the basic geography of the island and also will contribute very often for changing it on parts of it, thus making new relief forms in a short period of time.
- Tropical climate
  The tropical climate is the climate type that causes the fastest and most extreme erosion because of the almost daily rains, high temperatures, high humidity, and supports lots of plants and microorganism that contribute to the erosion. So the climate will contribute to the fast erosion of the very often created new relief forms, thus creating an interesting and versatile landscape on a small space.

The answer is cultural

Ibelieve it is the 2nd answer, create gardens on all rooftops. let me know if this .
