the worlds biomes

Rain forest

• Tropical rain forest are found near the equator,
• Temperate rain forest are found along the coast in a temperate zone,
• The climates of these forest are warm and cool,
• Trees in tropical rain forest's have a 50-100 year life span,
• Trees in temperate rain forest's have a 500-1000 year life span,

tropical thorn forest

• Dense dry vegetation,
• These forrest get as little as 10-20 inches of rain a year,
• These forrest are usually found in south west,Africa,Australia,
• Thorn forest turn into savanna woodland as the rain fall increases,
• Or if the climate becomes dryer thorn forrest will turn into dessert.

Chaparral

• The chaparral biome is found on most continents,
• This biome grows in small sections,
• The chaparral biome has many types of terrain,
• The climate in the summer is very hot and dry,
• During winter the climate can be very cool,

cold desert

• Cold desert's receive less then 10inches of rain/snow a year,
• Cold desert's are located all over the world, Peru,China,Usa,ext,
•  They are mostly located near the Arctic part of the world,
• All of these desserts are covered in sand dunes and stones,
• Animals burrow themselves into holes to survive the harsh winters, 

temperate grassland

• These grasslands are common in Northamerica,Southafrica,Australia,
• The climate depends on the latitude, But it is usually around 40 degreese,
• These grassland produce, salvia, oats, grass, wheat, barley, coneflowers,
• The rate of precipitation is about 500-900 mm of rain a year, 
• 25% of the earth is covered in the grass land biome,

Savanna

• The savanna is a grassland scattered with shrubs and trees,
• This biome can be compared to a tropical rain forrest and a dessert,
• Not enough rain falls in the savanna to support desserts,
• This biome is found in a wide band on either side of the equator,
• There are two very different seasons in the savanna ,winter,summer

hot desert

• Hot deserts don't have many plants due to lack of rain fall,
• The animals that live on the desert only come out at night,
• This is because they would not be able to live in the sun and heat,
• Desert cover about one fifth of the earth's land surface,
• Hot desert's get as little as 15cm of rain fall a year,

Polar ice caps

• The Polar ice caps are melting,
• polar ice caps do not have size, 
• Polar ice caps form because high latitude regios receive less energy from, 
• There are very little plants the grow in this biome,
• Animals that live in this biome are mostly penguins ,polar bears, sea life,

boreal forest

• The boreal forest is also called the Taiga,
• The boreal forest dose not have a warm climate,
• It has short hot summers and, cold long winters,
• The pine cone tree is on of the most popular in this biome,
• The forest also grows a variety of mosses,

Tundra

• The tundra is one of the coldest biomes,
• The tundra is also one of the world's youngest biomes,
• It was formed 100,000 years ago,
• The tundra is vast and tree less,
• There are 48 species of mammals that live in the tundra,

Alpine

• Alpine biomes are found in the mountain regions all over the world,
• The temperatures in the alpine can change from warm to freezing in a day,
• Plants and animals have learned to adapt to the drastic climate changes,
• The animals in this biome are being exposed to too much uv,
• Alpine animals have larger lungs due to the pressure at higher alititude,

Temperate evergreen forest

• Temperate evergreen forest are commonly found in costal regions,
• More then 300 species of birds live in this biome, 
• Many species of trees inhabit the forest, pine, ceder, fir, red wood,
• This forrest contains two layers an understory and an overstory,
• This biome is very sensitive to human activity such as hunting,

Temperate deciduous forest

• This biome can be found in north america,asia,europe,russia,japan,
• The climate in this biome is similar to fall temperatures go up to 50f,
• The average rain fall is 30 to 60inches a year,
• Most animals that live on these forest have to hibernate, 
• A lot of deciduous forest have lost land to farms and towns,
