Different parts of the earth receive direct rays of the sun for more hours of the day at certain times of the year

Causes changing seasonsoSummer solstice is the longest day of the yearoWinter solstice is the shortest day of the year

Equinox- days and nights are equal in length

18. and 19.

1. Latitude (think climate zones)2. Wind currents- spread the sun’s

heat (Coriolis Effect)3. Proximity to large body of water

(remember moderation)4. Elevation (remember it’s cold in

the mountains)5. Topography (ex. rain shadow)

Polar regions- area on Earth by the poles, very cold temperatures

Mid-Latitude/Temperate regions- area on Earth between the poles and above Cancer or below Capricorn, warm summers and cool winters

Low-Latitude/Tropical regions- area on Earth on the Equator, very hot temperatures

Biomes of the Earth

Students will be able to explain the influence of climate on the distribution of biomes in different regions.

What is a “biome”?•A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment.

•The climate and geography of a region determines what type of biome can exist in that region.

Qualities of a Biome•Water – how much, what kind

•Temperature - average•Soil – rock and/or poor vs. fertile

•Plants -- types•Animals -- types

AQUATIC BIOMES (water)

Marine Coral reef Estuaries

• TERRESTRIAL BIOMES (earth):

•Tundra •Rainforest •Savanna •Taiga •Temperate forest •Temperate grassland •Alpine •Chaparral •Desert

•Rainforest - Dense forests of different tree species; unique plants/animals living in balance.

•Savanna (Grassland) - Flat regions with few trees; grassy, many animals

Temperate Forests Biome

•Temperate Forests – Deciduous forest or mixed forests, many lose their leaves annually.

•Deserts – Plants/animals that conserve water and withstand heat; ex. cacti,

Taiga Biome

•Taiga - Sub-arctic coniferous (pine tree) forests; huge temperature variations between summer and winter.

Tundra Biome

•Tundra - Flat, treeless lands around the Arctic Ocean; permafrost, summer short and cool.

Research and Create poster•As a group, draw your biome, indicating the major factors of a biome.

•Your poster▫Should demonstrate:

Water Temperature Soil Plants Animals Areas of the globe where it exists!!! Title Effects of Man on the Biome

Notate the factors of your biome in your notebook.
