Climate Change
Final Science Exam Climate Change
Term | Definition |
---|---|
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 |
