Thermohaline current in North Atlantic
Earth scienceAsked by: Hector Carrasco What kind of current is the North Atlantic Current? warm western boundary current The North Atlantic Current (NAC), also known as North Atlantic Drift and North Atlantic Sea Movement, is a powerful warm western boundary current within the Atlantic Ocean that extends the Gulf Stream northeastward. How does the North Atlantic

Why is the concentration of nitrogen gas almost equal in soil air and the atmosphere?
Earth scienceAsked by: Hector Carrasco Which gas would always have higher concentration in the soil compared to the atmosphere? From the composition of soil air, we know that oxygen is much less than that of atmospheric air. On the other hand, carbon dioxide is higher in soil. Why does the percentage of gases like oxygen nitrogen

Zeolites, odor control, and the witchcraft of sunlight
Earth scienceAsked by: Steve Hlavaty What are zeolites PDF? Zeolites are aluminosilicate solids bearing a negatively charged honeycomb framework of micropores into which molecules may be adsorbed for environmental decontamination, and to catalyse chemical reactions. They are central to green-chemistry since the necessity for organic solvents is minimised. What is MFI zeolite? Abstract. High Resolution Image.

Public sources of topographical data of Earth?
Earth scienceAsked by: Steve Hlavaty Where can I get topography data? Topographic data are information about the elevation of the surface of the Earth.Digital Raster Graphics USGS Earth Explorer. USGS Seamless Server. USDA Geospatial Gateway (more info) What is the source of the elevation data? Ground survey is the oldest source of elevation data, traditionally undertaken

Cooling time of basalt flows?
Earth scienceAsked by: Gina Raybuck How long does it take for Basalt to cool? Lava cools very quickly at first and forms a thin crust that insulates the interior of the lava flow. As a result, basaltic lava flows can form crusts that are thick enough to walk on in 10-15 minutes but the flow itself

What is the evidence it is feasible to reverse ocean acidification by adding large quantities of a base (bicarb soda)?
Earth scienceAsked by: Gina Raybuck How do you reverse ocean acidification? The most effective way to limit ocean acidification is to act on climate change, implementing solutions to dramatically reduce the use of fossil fuels. If we dramatically cut our global warming emissions, and we limit future warming, we can significantly reduce the harm to marine

Does dirt compact itself over time? If so, how does this happen?
Earth scienceAsked by: Debbie Oksuz Will soil compaction over time? Regarding having something buried and soil compacting around it over time, yes that will occur but it is a question of how much stress the soil experiences, the duration of time and the nature of the soil – sandy or clayey. Something buried for a day

What is the ratio of energy absorbed by atmospheric CO2 from IR coming from the Earth vs directly from the Sun
Earth scienceAsked by: Debbie Oksuz What percentage of CO2 is absorbed by the atmosphere? When carbon dioxide CO2 is released into the atmosphere from the burning of fossil fuels, approximately 50% remains in the atmosphere, while 25% is absorbed by land plants and trees, and the other 25% is absorbed into certain areas of the ocean.

How to interpret the values of moisture flux convergence?
Earth scienceAsked by: Danielle Smith What is moisture flux convergence? Moisture flux convergence (MFC) is a term in the conservation of water vapor equation and was first calculated in the 1950s and 1960s as a vertically integrated quantity to predict rainfall associated with synoptic-scale systems. What is moisture flux divergence? Its horizontal divergence is the rate

What portion of global warming is caused by radioactive CO2 produced from cosmic rays?
Earth scienceAsked by: Danielle Smith How does cosmic radiation affect the climate? High-energy radiation from space, known as galactic cosmic rays, can affect Earth’s climate by increasing cloud cover and causing an “umbrella effect”, according to scientists. How does CO2 cause global warming? Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an
