Ecology 4.1 Climate

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

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

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

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)

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

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

POINT > Describe the Greenhouse Effect Atmosphere gets warmer

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

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

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

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?
