GEOS 218 Lecture Notes - Kuiper Belt, River Engineering, Water Table
Document Summary
Define: porosity- amount of air space between soil or rock particles. Permeability- = how well connected pore space is & how easily groundwater can flow. Aquifer- underground layer of permeable rock from which groundwater can be removed. Water table- top of the saturated zone in groundwater. Run off- it runs over the surface, downhill, toward a low point. Flash floods happen very fast regular floods take time. What does this video by nasa tell us about our ability to detect neo"s? we have been ale to detect neo"s for quite some time https://www. youtube. com/watch?v=vfvo-ujb_qk. Because larger impacts leave craters, and the largest can cause global changes. No protective atmosphere and no weathering/ erosion forces. Why is it hard to detect neo"s? size, speed, distances, and orbit proximity to the sun. The torino scale is a method for categorizing the impact hazard associated with near-earth objects such as asteroids and comets.
