How would one get a submarine to rise?
Earth ScienceAsked by: Mike Burrell How do submarines rise to the surface? In order to control buoyancy, the submarine relies on special tanks that can be filled with water or air. To return to the surface, the tanks are filled with air. This makes the submarine less dense than the water around it, causing the sub

Estimating Average Rainfall
Earth ScienceAsked by: Kira Huntington The grid point precipitation value is calculated based on the sum of the individual station weight multiplied by observed station value. Once the grid points have all been estimated they are summed and the sum is divided by the number of grid points to obtain the areal average precipitation. How do

Direct and Diffused component of shortwave radiation in ERA5 data
Earth ScienceAsked by: Richard Hernandez What is diffuse shortwave radiation? Shortwave solar radiation can be separated into two components: direct and diffuse beam. Diffuse beam is the portion of the radiation that has been scattered by gas molecules and suspended particles in the atmosphere and reaches the earth’s surface from multiple directions. What are the types

Is sea erosion the opposite of sea level rising (or rather, an adjacent phenomenon)?
Earth ScienceAsked by: Richard Hernandez Sea erosion is not the opposite of sea level rising, it is a direct consequence of it. How does sea level rise effect erosion? Sea level rise can also increase coastal erosion because waves can extend further up and along beaches and cliffs. Erosion is happening faster along coastlines made from

Is there any possible way that a tropical cyclone of any strength could form over land?
Earth ScienceAsked by: Joseph Salleh Would it be possible for a tropical cyclone to form over land? Because tropical cyclones need warm water to survive, the chances of tropical cyclone formation happening over dry land are slim. Only 2 percent of all Atlantic tropical cyclones have formed over land (1851-2015), according to Michael Lowry, hurricane specialist
