Over an extremely long periods of time, the movement of these plates create new biomes.

In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.

I. Forest.

II. Aquatic.

III. Desert.
