1. Ecology
4.1 Climate

2. POINT > Distinguish between weather and climate
POINT > Describe the Greenhouse Effect
POINT > Identify factors that affect climate

3. POINT > Distinguish between weather and climate
Weather describes day-to-day conditions of Earth’s atmosphere

4. POINT > Distinguish between weather and climate
Climate describes average conditions over long periods of time (year-after-year patterns)

5. POINT > Distinguish between weather and climate
Microclimate: Zone where climate differs from the surrounding area Ex. Tall buildings (different amounts of light, winds) Ex. Small areas (gardens) & large areas (urban places)

6. WB CHECK:
What is climate?
Give an example of a microclimate.
What is weather?

7. POINT > Describe the Greenhouse Effect
~ 30% reflected
Solar Energy & the Greenhouse Effect

8. POINT > Describe the Greenhouse Effect
Atmosphere gets warmer

9. POINT > Describe the Greenhouse Effect
The primary greenhouse gases are CO2, H2O, and CH4
The greenhouse effect is a natural phenomenon, but…
As greenhouse gas concentrations rise, more heat is trapped, warming Earth
Without any greenhouse effect, Earth would be about 30°C cooler

10. POINT > Identify factors that affect climate
1. Latitude & Solar Energy
Moving north & south of equator results in increasingly less direct (and less intense) amounts of solar energy

11. POINT > Identify factors that affect climate
2. Wind & ocean currents move heat & moisture throughout the biosphere

12. WB CHECK:
What are the 3 primary greenhouse gases?
What are 2 factors that affect climate?
What percentage of the sun’s energy is reflected back into space?
