The local climate determines the type of community that exists in an area. The type of community is referred to as a biome and examples include tropical rainforests, tundra and savanna.
Bare land, such as that produced by the new formation of islands, or land destroyed by lava, will naturally go through a series of changes until it reaches a stable stage known as a climax community. This process is known as succession.

- Analyse climate data for a range of locations. Use the Whittaker biome diagram to “predict” the biome of the location and compare with the known biome.
