🗑
|
||||

🗑
|
||||
| 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

| 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
🗑
|
||||

🗑
|
||||
| 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
🗑
