Document Summary
Climactic factors and geographic distribution of biomes, sources of climate variation beyond the basic latitudinal belts. General trends of terrestrial vegetation with climactic variables: Tropical forests are the most productive areas, deserts are the least. Regions with certain combinations of moisture and temperature develop predictable, characteristic vegetations = biomes. Stature of vegetation goes along with moisture, tend to nd tall forests in wet areas, and shrubby and shorter forests (grasslands) in dry areas. Seasonality is important, but less than moisture and temperature. Amount of plant growth is related to combination of moisture and temperature. *biome depends on amount of precipitation (rain) and temperature in an environment. A large community of plants and animals that occupies a distinct region. Terrestrial biomes, typically de ned by their climate and dominant vegetation, include grassland, tundra, desert, tropical rainforest, and deciduous and coniferous forests. *hot deserts are mostly around 30 north and south*
