Tundra is the world's coldest biome. Almost no trees can survive there due to the extremely low temperatures and short growing seasons. There are three types of tundra: Arctic and Antarctic, which are cold due to their latitude, and alpine tundra which is cold due to its altitude.
Latitude: An imaginary line that circles the earth, used to locate a position relative to the equator.
Taiga, also called coniferous forest, consists mostly of conifers. Taiga is the largest land biome, making up 27% of the world's forests. The largest area of taiga lies between the tundra to the north and the deciduous forests and grasslands to the south. Animals of the taiga include the snowy owl and caribou.
Conifers: Trees that grow needles instead of leaves and cones instead of flowers. These adaptations help conifers survive in areas that are very cold.
Deciduous forest regions are exposed to warm and cold air masses, which cause this biome to have four seasons. The temperature varies widely with the seasons. Plants become dormant to survive the cold winters, while summer birds fly south, and many mammals hibernate because food is scarce.
Deciduous: Trees, shrubs and other plants that shed their leaves seasonally. Deciduous trees are also called broadleaf trees.
There are two types of rainforest: tropical and temperate. Tropical rainforests are found closer to the equator where it is warm. More than half of the world's estimated 10 million species of plants, animals, and insects live in the tropical rainforests. Temperate rainforests are located along some coasts in temperate zones.
Grassland regions are open, fairly flat areas of grass. Grassland covers one fourth of the world's land. It can be found on every continent except Antarctica. Tropical grasslands, such as grass savanna, are hot and they receive only small to moderate amounts of rain. Temperate grasslands have warm summers and cold winters.
Desert is a barren region that receives very little rain. There are many types of desert but they share one characteristic: they receive no more than 10 inches of rain a year. Deserts are home to a surprising number of plants and animals suited to dry conditions. Over one-fifth of the world's land is desert.
