Dynamic of glacier retreat? (here: in Greenland)
Earth ScienceAsked by: Sierra Anderson What happens during glacier retreat? Glacial retreat leaves boulders and masses of scraped-together rocky debris and soil called glacial moraines. Large temporary lakes of glacial meltwater may rupture, causing catastrophic floods and even shifting global climate by dumping freshwater into the oceans and so altering their circulation. Why are Greenland glaciers

What is difference between an atmospheric model and a climate model?
Earth ScienceAsked by: Sierra Anderson What is the difference between climate models and weather models? Essentially, climate models are an extension of weather forecasting. But whereas weather models make predictions over specific areas and short timespans, climate models are broader and analyze long timespans. They predict how average conditions will change in a region over the

Are Bond cycles Dansgaard-Oeschger event(s)?
Earth ScienceAsked by: Grant Raymer What caused the Dansgaard-Oeschger? The events may be caused by an amplification of solar forcings, or by a cause internal to the earth system – either a “binge-purge” cycle of ice sheets accumulating so much mass they become unstable, as postulated for Heinrich events, or an oscillation in deep ocean currents

Why is there a logarithmic grid on this plot?
Earth ScienceAsked by: Grant Raymer Why use a logarithmic scale on a graph? There are two main reasons to use logarithmic scales in charts and graphs. The first is to respond to skewness towards large values; i.e., cases in which one or a few points are much larger than the bulk of the data. The second

Ocean Greenhouse Gases Released by Meteorite Impact
Earth ScienceAsked by: Lawrence Herrington What is meteorite impact in the ocean? Comets, meteorites or asteroids impacting against the planets are not unusual events. It is well known that such an impact on the ocean will produce large waves (tsunamis) that propagate away from the impact site up to reach the coastal areas (Wünnemann and Weiss

Why does the Earth have six atmospheric bands?
Earth ScienceAsked by: Lawrence Herrington Does the atmosphere have 6 layers? Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Why are the 5 layers of the atmosphere important? These five different layers provide protection and also make life possible
