Climate Change

Final Science Exam Climate Change

El Nino Unusual patterns of winds that form over the Pacific
La Nina Surface waters in the eastern Pacific are colder than normal
Global Warming The gradual increase in Earths atmosphere
Greenhouse Gases Gases in the atmosphere that trap gases
Chlorofluorocarbons (CFCs) Major cause of ozone depletion of a group of compounds
Coal Dirtiest fossil fuel-solid-most plentiful-formed from plant remains
Natural Gas Cleanest fossil fuel-gas-formed my animal and algae organisms
Oil Formed from animal and algae remains-liquid
Fuel Substance that provides energy such as heat, light, motion, electricity
Energy Transformation (energy conversion) Change from one form of energy to another
Combustion Fuels contain stored chemical energy which can be released by burning
Fossil Fuel Energy-rich substances formed from the remain of orginisms
Hydrocarbons Chemical compounds that contain carbon hydrogen atoms
Petroleum Another name for oil
Refinery Factory where crude oil is heated and separated into fuels and other products
Petrochemicals Compounds that are made from oil
Gases Carbon dioxide, methane, nitrous oxide, ozone
Most abundant and potent Water vapor
Ozone is Oxygen 3 , special gas that protects Earth from ultraviolet radiation
CFCs International laws eliminated
Ozone hole Shrinking
Greenhouse effect natural effect that insulates Earth and keeps
Climate change flowchart Man-made carbon emissions from fossil fuels-influx on greenhouse gases-greenhouse effect-global warming-climate change-ecological shifts that affect us
Ecological shifts that affect us Socially-financially-agriculturally-economically-enviormentally
USA oil and energy Third largest producer-imports 60%-needs to be energy independent
Fossil Fuels Will eventually run out
Effects of climate change Coral bleaching and ocean pH-weather and hurricanes-shrinking ice caps and poles-gulf stream and Europe
Stronger hurricanes There are more storms and they are becoming more big and intense- increase in ocean temperature and rising sea levels creates stronger
Effect on poles Poles are warming faster than rest of Earth- melting ice increases amount of land- land absorbs more heat than ice and radiates back into atmosphere
Current Large stream of flowing water that flows through oceans
Coriolis effect The effect of Earth's rotations on the directions of winds and currents
Climate The pattern of temperature and precipitation typical in an area over a long period of time
El Nino An abnormal climate event that occurs every 2-7 years in the Pacific ocean causing changes in winds, currents, and weather patterns for 1-2 years
Upwelling Tmovement of cold water upward from the deep ocean that is caused by wind
Gulf Stream Largest and most powerful surface current in the North Atlantic Ocean
West Wind Drift Stretches across the bottom and all of the world
Surface currents Affect water to a depth of several hundred meters and are mainly driven by winds
Deep currents Move and mix water from around the world
Upwelling affecting distribution of nutrients Brings more nutrients from deeper under the surface
Tides Caused by the interaction between the Earth, moon, and sun
Spring tide The greatest difference between a high and low tide
Neap tide The least difference between a high and low tide
Potential energy Energy that is stored and can be used
Salinity The total amount of dissolves salt in water
Submersible Underwater vehicle that is built of materials that resist pressure
Effect on poles They are warming faster than the rest of the world
Why poles are affecting climate change Ice melting creates more land and land ore absorbs heat than ice and radiates it back into the atmosphere
Stronger hurricanes There are more storms and they are becoming more intense
Stronger hurricanes affect on climate change Increase in ocean temperature and rising sea levels creates stronger storms
