1. Biome Notes

2. Tropical Rain Forest Located in warm areas near the equator.
Rains between inches a year.
Average Temperature is 77 with about 80% humidity all year long.
Divided into horizontal sections called the canopy, understory, and forest floor.

3. Desert Less than 25 cm or 10 inches a year.
Temperatures average 75 but can go much higher in the day
Plants have adaptations to store water.
Most of the deserts are located in Africa.
Only the hardy animals can survive in the desert due to the lack of rain.

4. Grassland Located on the interior of continents
Rolling plains characterized by few trees.
25-75 cm of rainfall a year is typical.
Usually have a predominate dry season and a wet season.
Home to some of the largest animals and herds.

5. Deciduous Forest Located in eastern US, Europe, and Asia.
Trees turn color and shed their leaves in winter.
Rainfall: at least 50 cm a year, which is enough for large plants and trees
Temperature: vary from very cold in winter to warm summer
Only biome with four distinct seasons

6. Tundra Permafrost: the soil is frozen all year
Very little rain, less than 15 cm
Temperatures are very cold and barely get above freezing in summer
Lichen and ferns are the few plants because they need little or no dirt
Caribou, foxes, wolves, and hares are some examples mammals that live here

7. Freshwater Almost no salt in the water
Located all over the world as lakes, ponds, swamps, and rivers
Many of the animals that live here are adapted to live on land and water.

8. Ocean
Divided into different zones including intertidal, neritic, surface, and deep zones
All the water has salt in it.
Tides occur when the moon’s gravity pulls on the water causing the water level to go up or down
Temperatures vary because they cover the entire world

9. Boreal Forest
North of most deciduous forests in America, Europe, and Asia
Trees are coniferous meaning they have pines or cones
Temperature is very cold, but warm enough to melt snow in the summer.
Rainfall is about the same as deciduous
Also called the Taiga
