Can Volcanic Eruptions Help Combat Global Warming in the Long Run?
Earth ScienceAsked by: Christine Harris Do volcanic eruptions help global warming? While sulfur dioxide released in contemporary volcanic eruptions has occasionally caused detectable global cooling of the lower atmosphere, the carbon dioxide released in contemporary volcanic eruptions has never caused detectable global warming of the atmosphere. How can volcanoes be beneficial to ecosystems over a long
Is there any link between sea-water inflitration into groundwater and nitrate?
Earth ScienceAsked by: Christian Myers What sources cause nitrates in groundwater? Nitrates can get into groundwater from many sources, including fertilizers, manure on the land, and liquid waste discharged from septic tanks. Natural bacteria in soil converts various forms of nitrogen into nitrate. Rain and irrigation water can carry nitrate down through the soil into groundwater.
Why does NW coast of Scotland look like it does? (Similar to Norway, so different to other European coastlines)
Earth ScienceAsked by: Christian Myers These are actually a geological feature called “fjord” which the Scandinavian Peninsula and surroundings (including Scotland) are known for. It is the result of glacial erosion during the Ice Ages. Was Scotland connected to Norway? Scotland and Norway share strong links that stretch right back to Viking times. Northern Scotland, was,
Is the Earth heated up by the tides?
Earth ScienceAsked by: Carlos Rothstein Tidal forces contribute to heating in Earth’s interior. “The tides generate friction, and friction leads to heat,” explained René Heller, a scientist at the Max Planck Institute for Solar System Research and a lecturer at the University of Göttingen in Germany. Do tides produce heat? Tidal heating (also known as tidal
What influences the movement (speed and direction) of tropical cyclones?
Earth ScienceAsked by: Carlos Rothstein What influences the movement of a tropical cyclone? Tropical cyclone tracks Their motion is due in large part to the general circulation of Earth’s atmosphere. Surface winds in the tropics, known as the trade winds, blow from east to west, and they are responsible for the general westward motion of tropical
Why are oceans so deep?
Earth ScienceAsked by: Jessica Moore The extreme depth of the Mariana TrenchMariana TrenchThe Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and
