🗑
|
||||
| What's the 2nd Law of Thermodynamics? | When energy is changed from one form to another, some useful energy is always degraded into lower quality energy (usually heat).
🗑
|
||||

🗑
|
||||
| What's Best Soluion to Energy Shortage? | Conservation & increase efficiency.
🗑
|
||||
| What's Surface Mining? | Cheaper & cn remove more mineral, less hazardous to workers.
🗑
|
||||
| What's Humus? | Organic, dark materials remaining after decomposition by micoorgamnisms.
🗑
|
||||
| What's Leaching? | Removal of dissolved materials from soil by water moving downwards
🗑
|
||||
| What's Illuviation? | Deposit of leached material in lower soil layers (B)
🗑
|
||||
| What's Loam? | Perfect agicultral soil wth equal portions of sand, silt, & clay.
🗑
|
||||
| What's Solutions to Soil Problems? | Conservtion tillage, crop rotation, contour plowing, organic fertillizers.
🗑
|
||||
| What's Parts of the Hydrologic Cycle? | Evaporation, transpiration, runoff, codenation, precipitation, infiltration.
🗑
|
||||
| What's Aquifer? | Any water bearing layer in the ground.
🗑
|
||||
| What's Cone of Depression? | Lowering of the wter table around a pumping well.
🗑
|
||||
| What's Salt Water Intrusion? | Near the cost, overpumping of groundwater causes saltwater to move into the acquifer.
🗑
|
||||
| What's ENSO? | El Nino Southern Oscillation, see-sawing of air pressure over the S. Pacific.
🗑
|
||||
| What's During an El Nino Year? | Trade winds weaken & warm water sloshed back to SA
🗑
|
||||
| What's During a Non EL Nino year? | Easterly trade winds and ocean currents pull warm water in the western Pacific, allowing upwelling of nutrient rich water off the West coast of South America
🗑
|
||||
| What's Efects of El Nino? | Upwelling decreases disrupting food chains, N US has mild winters, SW US has ncreased rainall, less Atlantic Hurricanes.
🗑
|
||||
| What's Nitrogen Fixing? | Because atmospheric N connot be used directly by plants, it must first be converted into ammonia by bacteria.
🗑
|
||||
| What's Ammonification? | Decomposers convert organic waste into ammonia.
🗑
|
||||
| What's Nitrificaion? | Ammonia is converted to nitrate ions (NO-3)
🗑
|
||||
| What's Assimilation? | Inorganic N is converted ito orgnic molecules such as DNA/amino acids & proteins.
🗑
|
||||
| What's Denitrification? | Bacteria convert ammonia back into
🗑
|
||||
| Why Phosphorus does not circulate as easily as N? | Because it does not exist as a gas, but is releases by weathering of phosphate rocks.
🗑
|
||||
| Why soils contains very little phosphorus? | Because it is a major limiting factor for plant growth.
🗑
|
||||
| How excess phosphorus is added to aquatic ecosystems? | By runoff of animal wastes, fertiizers discharge of sewage.
🗑
|
||||
| What's Photosynthesis? | Plants convert atmospheric C (CO2) into comlex carbohydrates (glucose C6H12O)
🗑
|
||||
| What's Aerobic Respiration | Oxyen consuming proucers,consumers & decomposers break down complex organic compounds & convert C back into CO2
🗑
|
||||

🗑
|
||||

🗑
|
||||
| Why is only 10% transferred? | Usable energy lost as heat(2nd Law), not all biomas is digested & absorbed, predators expend energy to catch prey.
