Compare and Contrast: Tundras, Temperate Grasslands, and Tropical Rain Forests
Chapter 3 Project

A
Tundra
is a biome without trees with a frozen layer of soil called permafrost.
Caribou, polar bears,birds, insects, wolves, trout, and salmon inhabit the tundra.
The Tundra has a temperature range of -34°C to 12°C.
The Tundra has 15 to 25 cm of precipitation per year,
In the summer the ground thaws to only a few centimeters; not enough to support tree roots.
Shallow rooted plants such as short grasses and shrubs are supported in the Tundra.
Constant freezing and thawing occurs.
No trees
The Tundra
A
temperate grassland
is a biome that has fertile soils that support a thick cover of grass.
Temperate grassland is found in North America, South America, Asia, Africa, and Australia.
The average temperature range of temperate grasslands is -40°C to 38°C.
Temperate grasslands have 50 to 89 cm of precipitation a year.
Supports thick grasses and herbs.
Fires prevent temperate grasslands from becoming forests.
No trees
Hot summers and cold winters.
Horses,lions,deer,mice,coyotes,foxes,birds,snakes,wolves,and gazelles inhabit temperate grasslands.
Temperate Grassland
A
tropical rain forest
is a biome with very warm average weather conditions determined by latitude,or
climate
.
Latitude
is the distance of a point on Earth's surface north or south of the equator.
Tropical Rain forests are found in Central and South America, Southern Asia, Western Africa, and Northeastern Australia.
Tropical Rain Forests have an average amount of 200 to 1000 cm of precipitation per year.
The temperature range is 24°C to 27°C.
It is always hot,wet and humid.
Broad leaved trees with mosses and ferns on the branches.
Cobra snakes, toucans, Bengal tigers, elephants,bats, orangutangs, sloths, and chimpanzees inhabit tropical rain forests.
Tropical Rain Forest

There are many similarities and differences of the tundra, temperate grasslands, and tropical rain forests. Tundras and temperate grasslands both cannot support trees, however they cannot support trees for different reasons. Tundras permafrost prevents trees from growing and fires prevent trees from growing in temperate grasslands. Also, tundras and temperate grasslands both support grass but, tundras have short grass while temperate grasslands have thick grasses.

Temperate grasslands and tropical rain forests can be found in South America and Australia. Tropical rain forests support broad leaved trees with thick mosses and ferns on the branches, unlike the tundra and temperate grasslands. Wolves and birds inhabit both tundras and temperate grasslands.
Compare and Contrast
Vocabulary Words:
Tundra: Treeless biome with a layer of permafrost.
Temperate Grassland: Biome with fertile soil that supports thick covers of grass.
Climate: Average weather conditions in a specific area determined by latitude,elevation,and ocean currents.
Tropical Rain Forests: A biome that is characterized by warm temperatures and large amounts of rain.
Latitude: Distance of point on Earth's surface north or south of the equator.
