Allushta [10]

<u>Temperature, humidity and elevation </u>are the two major factors determining the distribution of terrestrial biomes.

  • The Terrestrial biome type is influenced by variables including latitude, humidity, and elevation:

  • The amount of water in the air is known as humidity. Humid air is defined as having a high concentration of water vapor.
