Do now activity What is the difference between logistical and exponential population growth? What is the difference between a pioneer and climax community? If the population of deer in 2016 was 4,000 and 500 deer were born in 2017, what is the current population size? In 2016, Georgia had a population of 300 people. In the same year, 25 babies were born & 15 people died. In the same year, 10 people immigrated and 5 people emigrated. What was the population growth of Georgia for 2016?

Overview EARTH ______ is the only planet with an adequate temperature able to sustain life.

Overview weather: the day-to-day condition of the Earth’s atmosphere at a particular time and place

climate climate: the average, year-after-year conditions of temperature and precipitation

climate The Effect of Latitude Because of Earth’s shape some areas receive more direct sunlight than others There is ___ heat at equator than the poles MORE

climate 3 Climate Zones Tropical zone: very warm zone, receiving mostly direct sunlight all year Polar zone: cold zone that receives low angle rays Temperate zone: between polar and tropics and ranges from hot to cold depending on changing angle of the sun ECOLOGY

climate Polar zone: cold zone that receives low angle rays 3 Climate Zones Tropical zone: very warm zone, receiving mostly direct sunlight all year Polar zone: cold zone that receives low angle rays Temperate zone: between polar and tropics and ranges from hot to cold depending on changing angle of the sun ECOLOGY

Heat transport Unequal heating of Earth’s surface drive wind and ocean currents Convection currents between the poles and equator cause the wind and ocean to move heat (example: upwelling) Land masses can block wind currents

greenhouse effect Greenhouse effect is when gases in the atmosphere trap heat energy Maintains the Earth’s temperature Humans have increased these gases

List 5 factors that can contribute to the climate of an area. Do now activity List 5 factors that can contribute to the climate of an area.

Factors that contribute to climate Heat trapped in atmosphere Latitude How far North or South you are on the planet Movement of heat by winds and water currents Amount of precipitation Shape and elevation of land masses
