Define ALL of the following words in your notes Greenhouse Effect Global Warming Deforestation Desertification Acid Rain Soil Erosion Habitat Fragmentation Invasive Species Biological Magnification Endangered Species Pollutant
In your notes! In my own words… 1.Biological Magnification-
Biological Magnification DDT is an insecticide that was used in the 1940s and is now illegal because can be cancer causing in animals (including humans) Biological Magnification is how effects of DDT spread Through the food chain (Trophic levels) https://www.youtube.com/watch?v=RP9hmlRqbxs
Biological Magnification How would you explain it? – Put it into your own words in your notes.
Desertification The 1930s Dust Bowl in the Great Plains of the United States. Presently desertification affects millions on almost every continent. https://www.youtube.com/watch?v=w9RxnuBiFbg Not the growth of deserts, but the drying out of fertile lands.
Desertification How would you explain it? – Write it in your own words.
Deforestation The worlds rain forests could completely vanish in a hundred years at the current rate of deforestation. https://www.youtube.com/watch?v=M4jhjt1_eyM https://www.youtube.com/watch?v=M4jhjt1_eyM
Deforestation How would you explain it, put it into your own words… How can we solve this problem?
Soil Erosion A problem for productive agriculture and water quality. https://www.youtube.com/watch?v=Xdg1lpQfLbo How would you explain it, put it into your own words…
Habitat Fragmentation Concerns are direct loss of habitat and also direct and indirect effects from the pipelines, roads, and other disturbances with the natural gas drilling sites. https://www.youtube.com/watch?v=xGBQFZHHKcc https://www.youtube.com/watch?v=xGBQFZHHKcc How would you explain it? Put it into your own words
Endemic Species – A species that is unique and confined to a specific habitat. Succession - the process of a ecosystem giving rise to plants and eventually wildlife. Ozone depletion – A steady decline in the total volume of the Earths ozone in the stratosphere
Invasive Species http://www.cbsnews.com/news/the-threat-of-invasive-species/
Invasive Species in PA The Black and Brown Rat: introduced to the U.S. in the middle ages from European shipping transports. Asian Lady Beetle: introduced from Asia looks like a lady bug, but it bites. Swarms homes this time of year for winter. Brown Marmorated Stinkbug: from China, Japan and Korea, accidentally introduced in the U.S. Discovered in Allentown, PA in 1998, and has spread throughout the state. It is an agricultural hazard because it feeds on fruit trees.
Endangered Species http://www.cbsnews.com/news/the-endangered-species-act-turns-40/ In Pennsylvania 2 Animals on the list. Eastern massasauga: venomous snake Rabbitsfoot: freshwater mussel
Endemic Species Isolated on an island, these species are found only in one particular area of the world (naturally). Can you think of any? …. Heres one http://video.nationalgeographic.com/video/lemur_mouse
Ozone depletion Ozone protects us from UV radiation (causes sun burn) Decreasing the amount of ozone, increasing risks of the sun harming our skin. It is depleted by chlorofluorocarbons (CFCs) human made chemicals. CFCs are in aerosol cans, refrigerators, Air conditioners, and many more. https://www.youtube.com/watch?v=qUfVMogIdr8
Climate vs. Weather The difference between weather and climate is a measure of time. Weather = conditions over a short period of time. Climate = conditions " over relatively long periods of time. (Decades) Climate changes happen slower than weather changes. http://video.nationalgeographic.com/video/climate-weather-sci
How do we know about past climates? 1.Ice core data 2.Tree Rings 3.Sediment cores https://www.windows2universe.org/earth/climate/paleoclimate_proxies_nsf.html
In the past 50-60 years Global temperatures have risen 1 – 2 degrees Celsius Rising temperature causes melting, causing a greater rise in temperature. – Albedo Effect – https://www.youtube.com/watch?v=cW4JTHz1aRg https://www.youtube.com/watch?v=cW4JTHz1aRg
