Presentation Transcript

  1. SEASONS • 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 seasons • Summer solstice is the longest day of the year • Winter solstice is the shortest day of the year • Equinox- days and nights are equal in length

  2. 18. and 19.

  3. CLIMATE FACTORS Latitude (think climate zones) Wind currents- spread the sun’s heat (Coriolis Effect) Proximity to large body of water (remember moderation) Elevation (remember it’s cold in the mountains) Topography (ex. rain shadow)

  4. WIND CURRENTS • Hot air flows toward the poles and cold air moves toward the equator

  5. 20. #20

  6. OCEAN CURRENTS Large, circular systems • Warm water flows away from equator toward the poles • Cold water flows back towards the equator

  7. A climograph shows precipitation and temperature for a specific region Moosonee, ON Phoenix, AZ

  8. Climate Zones Cancer Capricorn

  9. Polar regions- area on Earth by the poles, very cold temperatures Low-Latitude/Tropical regions- area on Earth on the Equator, very hot temperatures Climate Regions Mid-Latitude/Temperate regions- area on Earth between the poles and above Cancer or below Capricorn, warm summers and cool winters

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

  11. 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.

  12. Qualities of a Biome • Water – how much, what kind • Temperature - average • Soil – rock and/or poor vs. fertile • Plants -- types • Animals -- types

  13. TYPES OF BIOMES… • TERRESTRIAL BIOMES (earth): • Tundra • Rainforest • Savanna • Taiga • Temperate forest • Temperate grassland • Alpine • Chaparral • Desert • AQUATIC BIOMES (water) • Freshwater • Freshwater wetlands • Marine • Coral reef • Estuaries

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

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

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

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

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

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

  20. 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.

  21. Chart for notebook

  22. Gallery Walk • Take a stroll and fill in your chart using the research of your peers!

  23. Ultimate Chart

  24. Take the Quiz as a Class! • To Plant or Not to Plant – Biome Match http://earthobservatory.nasa.gov/Experiments/Biome/
