PRESENTATION OUTLINE
RAIN FOREST
- This is a forest of tall trees and a place of year round warmth.
- An average of 50 to 260 inches of precipitation falls yearly.
- Some trees have "drip spouts" that allow's rain to run off.
- This keeps mold and mildew from growing.
- More than half of the worlds animals and plant live here.

DESERT
- The desert doesn't have very many plants especially hot and dry deserts .
- Desert cover about 1/5 of the earths surface.
- Desert vegetation is very very rare.

GRASS LAND
- The prairies contain more than 80 species of animals
- ,300 species of birds, and hundreds of species of plants.
- Grassland biomes are large, rolling terrains of grasses, flowers and herbs.
- This biome can be found in the the middle latitudes and interior continents.
- The soil on most grasslands is too thin and dry for trees to survive.

DECIDUOUS FOREST
- Deciduous forests are found in the eastern half of North America, and the middle of Europe.
- Rainfall is 30 to 60 inches a year,in a deciduous forest the average temperature is 50° F.
- The animals adapt to the climate by hibernating in winter and live off land in the other three seasons.
- Plants adapt by leaning toward the sun.Soaking up nutrients in the ground is an adaptation.

TAIGA
- Biomes are habitats,like mountain tops,deserts,tropical forests,and are determined by the climate.
- The summers are mostly warm,rainy and humid,not many plants can survive the cold of the taiga winter.
- Trees have adapted by growing thick bark,The taiga is susceptible to many wildfires.
- Red deer, elk, and moose are found in regions of the taiga where most deciduous trees grow.
- Taiga is also known as boreal forest.Taiga is the Russian for forest and is the biggest biome in the world.

TUNDRA
- The Arctic Tundra is the youngest world biome.
- Almost all tundras are located at the Northern Hemisphere.
- The average temperature is -18° F (-28° C).
- Most shrubs, sedges, mosses, lichens and grasses, grow here.
- 48 species of land mammals are found in the tundra, there is a lot of each species.

MOUNTAINS AND ICE
- They are usually at an altitude of 10,000 feet and or more.
- In the summer the average temperatures are in range from 10 to 15° C.
- In the winter the temperatures are below freezing.
- There are only warm blooded animals and some insects in the alpine.
- There are only about 200species of plants,after they die they don't decompose fast because of the cold.
MARINE
- Marine water covers about three-fourths of Earth’s surface.
- Especially in oceans, coral reefs, and estuaries.
- Algae supplies much of the world’s oxygen and takes in huge amounts of atmospheric carbon dioxide.
- Evaporation of the seawater provides rainwater for the land.

FRESH WATER
- usually less than 1% of Plants and animals in the freshwater have adjusted to the low salt content.
- There are about 4 or 5 different types of fresh water zones.
- ponds,lakes, streams, rivers, and wetlands are some types of fresh water zones.
