Biomes of the Earth
ForestsThere are three types of forests…
1.) Temperate Deciduous Forests
2.) Tropical Rain Forests
3.) Taiga (Coniferous Forests/Boreal Forests)
Temperate Deciduous Forest
Temperate Deciduous Forest
• Deciduous means “to fall off” – the trees in this region have leaves that fall off.
• We live in a temperate forest!
• Rainfall – 75 – 125cm• Temp.- Summer – 28C, 82F
Winter– 6C, 43F
Temperate Deciduous Forest’s are typically found in the northern hemisphere.

Tropical Rain Forest
Tropical Rain Forest• More species live here than any other biome
• Canopy – treetops in the rainforest. Most animals live there
• Very little light reaches the ground b/c of the canopy
• This is the wettest and warmest biome• Rainfall – up to 400cm• Temp.- Daytime– 34C, 93F
Nighttime– 20C, 68F
The world’s rainforest’s are found in tropical locations near the equator.

Taiga
Taiga• This biome has long cold winters• Have evergreen trees – trees that stay green all
year long.• Conifers are trees that produce seeds in cones
and have needle-like leaves (pine trees)• Animals in this biome often hibernate or migrate• This is the largest biome• AKA: coniferous forest and boreal forest
Taiga
•Rainfall – 35 - 75cm•Temp.- Summer – 14C, 57F
- Winter – -10C, 14F
The taiga is only found in the northern hemisphere and it’s the largest biome

Grasslands
-Grasses are the main vegetation.
-There biomes are typically found between forests and deserts.
-These biomes exist on every continent.
-They are also known as plains, prairies, savannas, and steppes.
Temperate Grassland
Temperate Grasslands
•This biome has mixed grasses with various plants and a few trees
•Rainfall – 25-75cm•Temp.- Summer – 30C, 86F
Winter – 0C, 32F
Savanna
Savanna• Tropical grassland with scattered clumps of trees.• It has a rainy season and a dry season. • The majority of the world’s savannas are in
Africa.
• Rainfall – 150cm• Temp.- Rainy Season – 16C, 61F
Dry Season – 34C, 93F

Desert
Desert• Hot and dry with a variety of plants and animals.• Animals are most active at night (nocturnal)• This is the biome with the least rainfall
• Rainfall – less than 25cm• Temp.- Summer – 38C, 100F
Winter – 7C, 45F
The Earth’s Deserts

Tundra
Found in the far north and on the tops of mountains.No trees are found in the tundra.It is the coldest biomeThere are two types of tundra: artic and alpine
Tundra
Arctic Tundra
• Has permafrost which stays frozen year round• Water is available and the surface is wet and
soggy• Lakes and ponds are plentiful
Alpine Tundra• Lots of sunshine and precipitation in the form
of snow• Located above the tree line of tall mountains
The tundra is located above the taiga in the northern hemisphere
