Desert Biomes
Tropical Desert (Sahara) - very hot year round, dry, windy, sand and rocks, very little vegetation.
Temperate Desert (Arizona) - high temperatures during the summer, low temperatures during the winter, occasional rainfall, sparse vegitation.
Polar Deserts (Poles) - sub-freezing, no true vegitation (producers are in ocean), blizzards.
Grassland Biomes
Tropical Grassland (Savanna) - hot year round, dry season with little rainfall, wet season with alot of rainfall, grass and hardy trees/shrubs.
Temperate Grassland (Great Plains in North America) - hot, dry summers, cool winters, seasonal fires, lots of grass.
Polar Grassland (Tundra) - below freezing except during a short summer period, permafrost, short hardy plants and grasses grow during the summer then die.
Semidesert (Scrubland, Chaparral, Southern California) - between desert and grassland areas, brief sometimes heavy rains in winter, warm year-round, shrubs and grasses.
Forest Biomes
Tropical Rainforest - hot year round, little if any seasonal variations, rain almost daily, high humidity, very high biodiversity.
Temperate Deciduous Forest - warm summers, cool winters, trees loose their leaves during winter to survive.
Evergreen Forests - cooler summers, cold in winter, coniferous trees
Temperate Rainforests (Redwood Forests in Northern California) - Temperate Forests near the coast, meaning that the ocean moderates the temperature and causes more mild temperature extreames, lots of rain, moist, evergreens.
Mountain Biomes - mimic biomes farther away from the equator depending on height, for example, Evergreen Forests could be found on the equator if utop a sufficiently tall mountain range (essentially altitude makes things colder), often have unique wildlife, snow from winters melts over summer, creating rivers for lower biomes.
