9/24/13 Objective: How are humans impacting the environment? Do Now: What is this picture depicting?
What is the function of this greenhouse? Sunlight passes through the glass, where the interior absorbs the radiant energy changing it to heat, the glass stops the heat from escaping
The Greenhouse Effect
Greenhouse gases (CO2, N2, methane, water vapor) trap infrared heat and keep the Earth warm
Global Warming Carbon dioxide from the burning of fossil fuels adds too many greenhouse gases, resulting in increases in the Earth’s temperature
What is this graph showing?
Increased probability and intensity of droughts and heat waves
Global Warming Melting of the polar ice caps can raise sea levels –Puts more freshwater into the ocean –Can cause endangerment of animals
The Ozone Layer The ozone layer: a layer of gases that absorbs radiation from the sun
Ozone Depletion The ozone gets depleted (gets holes in it) when cleaners, air conditioners and refrigerators are used and release chemicals called chlorofluorocarbons (CFCs) into the atmosphere.
So What? - Without ozone, more UV rays hit earth - Holes in the ozone can lead to higher rates of skin cancer.
Endangered Endangered animals are still living today but are in immediate danger of extinction.
Threatened A species that is likely to become endangered if it is not protected.
Captive Breeding Programs
Preserving Genetic Material
Zoos, Aquariums, Parks, Gardens
Impact on Water Cycle Pollutants such as fertilizers,, pesticides, oil, sewage Acid rain from sulfur dioxide reacting with water
Impact on Carbon Cycle Burning of fossil fuels (oil, gas, coal) Deforestation
STRAND 4 EARTH AND SPACE SCIENCE ESS.8.8.1
GENERAL SCIENCE MR. J. PRUSHINSKI EE 4.3: Air Pollution & Solutions.
The atmosphere is a layer of gases that surround the Earth. These layers differ in temperature, in density, and in the relative amounts of the different.
Aim: How is the earth's atmosphere similar to a greenhouse?
AIR POLLUTION Composition of Air:
ENVIRONMENTAL SCIENCE II FINAL EXAM REVIEW UNIT 3: AIR POLLUTION Final Exam will be on Wednesday June 10, 2015 The final exam is worth 20% of your final.
How are we affecting the Environment?. 1. Air pollution a.Smoke, dust and exhaust fumes will pollute the air b. Smog – a form of air pollution that is.
Ozone & Greenhouse Effect. What is Ozone? Ozone is a molecule that occurs in the Stratosphere Ozone absorbs harmful UV rays from the sun O 3 + uv O 2.
Greenhouse Effect - Natural Heating of Earth’s surface by certain atmospheric gases.
Energy in the Atmosphere
GLOBAL WARMING AND OZONE DEPLETION Agenda Continuation from yesterday Independent Practice Articles & Follow Up Questions.
Human Impact on the Environment:
Air Quality - Pollution
Unit 4 Human Impact on the Environment. Population Three factors that affect population: –Number of births –Number of deaths –Number of individuals that.
Ozone depletion Ozone is O3.
PP : ENVIRONMENTAL ISSUES. Pollution Putting substances that cause unintended harm into the air, soil, or water.
The Greenhouse Effect. A lot of the light that comes from the sun, doesn’t make it to the surface of the earth.
Environmental Effects of Overpopulation
Ozone & Global Warming What’s the difference??? What is Ozone? Ozone - A variety of Oxygen that has 3 oxygen atoms and is an odorless and colorless gas.
