2. WHAT AFFECTS CLIMATE?
Climate in an area is affected by two main things
Direct sunlight (heat)
Precipitation
Climate directly affects the type of biome
Biome is an environment with specific vegetation and organisms
If it is cold, you have organisms that are suitable to the ____
3. BIOMES
Because of these two factors combined, we get specific biomes at specific areas.
For example, at the equator, there is a lot of sunlight, and a lot of precipitation, so there is a
tropical rainforest.
At 30°, there is a lot of sunlight, but little or no precipitation, so there is a desert.
4. OVERVIEW
Sunlight and precipitation affect the climate
Climate over an environment produces a biome
A biome has organisms suited to the climate
Biomes generally occur on the same latitudes
5. BIOMES
There are two main types of biomes
Land
Aquatic (water)
We will cover both today
6. LAND BIOMES
Most land biomes are named after their climax community.
Some of the land biomes
Tundra
Taiga (TIGH-guh)
Temperate deciduous forest
Grassland
Tropical rain forest
Desert
8. AQUATIC BIOMES
There are 3 main types of aquatic biomes.
The amount of salt determines the type of biome.
The 3 main types of aquatic biomes
Freshwater
Marine (saltwater)
Estuaries
9. TUNDRA
Tundra
Located near the poles
Treeless biome covered by moss, lichens, and grasses
Permafrost – a layer of permanently frozen subsoil
10.
11. TAIGA (BOREAL FOREST)
Taiga
Covered by coniferous (cone bearing) trees.
Bears, wolves, moose, elk are some of the typical animals
Coniferous Forest

14. TEMPERATE BIOMES
Temperate climates characterized by cold winters and hot summers
Plants change during the seasons (leaves change color)
Deciduous Forest, Woodland & Shrubland, Grassland
20. TROPICAL RAIN/DRY FOREST
Tropical rain forest
Located at equator
Receive 200-400 centimeters of rain a year
Constant temperature.
Home of the most types of animals than any other biome. Many colorful
Dry forest: less precipitation
21.
22.
23. DESERTS
Deserts
Located at 30° latitude
Less than 25 cm of rain falls a year
Both plants and animals must be able to retain moisture.
Birds, lizards, snakes, insects are typical
Cactus and sagebrush sparsely cover the area
29. MARINE BIOMES
Includes all of the ocean
Marine biomes are divided into 4 subcategories
Intertidal zone
Neritic zone
Open-sea zone
Deep-sea zone

33. ESTUARIES
Estuaries are the boundaries between freshwater and saltwater.
Since it is a mix of the two, a variety of organisms can be supported.
Examples of estuaries
Delta, swamp, lagoon

36. BIOME PROJECT
In groups of 3-4, create a biome presentation
Give information about the biome, including:
Temperature range (graph)
Precipitation (graph)
Location (latitudes/areas)
Plants (vegetation)
Animals
Interesting Facts
Posterboard or Powerpoint acceptable
More visuals, the better
500000000 points
Due in two weeks!

What kind of presentation will you do? Powerpoint? Posterboard?
Who is doing what? Research? Picture finding? Who’s good with
computers? Who’s bringing materials?
When do you want to meet up? Contact info?
