- 2. 4.1 The Role of Climate Climate: The average annual weather conditions in a region. Weather: The current conditions of the atmosphere at a particular time and place, this can include: rainfall, temperature, humidity, winds, etc.
- 3. 4.1 The Role of Climate Atmospheric gasses such as Carbon Dioxide, Methane, CFCs, Ozone, and Nitrous Oxide trap heat inside of Earth’s atmosphere. The heat energy from the sun passes through them into the atmosphere, bounce off the ground, upwards, then bounce off the gasses. They continue to do this, continually heating Earth’s surface. These gasses that trap heat inside of Earth’s atmosphere are called: Greenhouse Gasses
- 4. 4.1 The Role of Climate The unequal heating of Earth’s surface contributes to climates. As one moves farther away from the equator(toward the north or south pole), one is also moving farther away from the sun. This causes temperatures farther away from the equator to be much lower. This also causes oceans and air to heat unequally, causing the flow of winds and ocean current, this also affects climates.
- 5. 4.1 The Role of Climates Climate is a large factor in ecosystems, and can change them in significant ways If temperatures rise in an ecosystem, it will cause the populations that are better adapted to heat to swell, and populations that are better adapted to colder climates to shrink. If rainfall decreases in an ecosystem, it will cause the populations that are better adapted to dry conditions to swell, and populations that are better adapted to wetter climates to shrink. It may even cause some populations to die out altogether.
- 6. 4.2 What Shapes an Ecosystem?
- 7. 4.3 Biomes Biome: A group of land communities that covers a large area and has a certain soil type and climate. It is possible for microclimates to exist within biomes Microclimate: A small area where the climate differs from that of the surrounding area.
- 8. 4.3 Biomes There are ten major biomes that exist on Earth Tropical Rainforest Tropical Dry Forest Tropical Savanna Desert Temperate Grassland Temperate Woodland/Shrubland Temperate Forest
- 9. 4.3 Biomes Each biome consists of its own assortment of abiotic factors and typical organisms Different biomes are able to provide for different types of organisms, therefore different types of organisms will evolve within them and create different types of ecosystems
