Is there a list of instances where mountains that have been mined out of existence?
Earth scienceAsked by: Quintin Prestige What is the oldest mine in the world? The Ngwenya Mine The Ngwenya Mine is located on Bomvu Ridge, northwest of Mbabane and near the northwestern border of Eswatini (Swaziland). This mine is considered to be the world’s oldest. What is mining in geography? Mining is the process of extracting useful

What is the difference between w-wind, vertical p-velocity and Omega?
Earth scienceAsked by: Tracey White What is omega vertical velocity? Omega is the vertical velocity in pressure coordinates (so positive omega is negative w). Omega has units of pressure per time. Because much of the operational meteorology uses pressure surfaces, omega is a more common quantity to see. What is omega in wind? Contact Us. T-Omega

Rainfall units conversion from depth to rate/intensity
Earth scienceAsked by: Tracey White In order to have the average rainfall intensity in m/s corresponding to that interval of time, you have to divide the rainfall depth for the number of seconds in the time interval or for mm/s you multiply for 1000/21600. If you want the intensity in m/h you divide for 6 hours.

Why does the moon orbit the earth and not the sun instead?
Earth scienceAsked by: Lynn Logan The force of the gravitational force of earth is more than the sun on moon.So the moon revolves around the earth not the sun. Why does the moon orbit the earth instead of the earth orbiting the moon? Earth is larger than the moon, so Earth pulls on the moon. At

How does the lack of data about the Mesosphere affect our predictive knowledge of the atmosphere?
Earth scienceAsked by: Lynn Logan Why do we know so little about the mesosphere? The mesosphere is difficult to study, so less is known about this layer of the atmosphere than other layers. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure the

Publicly available data set with ensemble forecasts and observations?
Earth scienceAsked by: Robby Filippi Why do we use ensemble forecasts? Ensemble forecasting is a method used in or within numerical weather prediction. Instead of making a single forecast of the most likely weather, a set (or ensemble) of forecasts is produced. This set of forecasts aims to give an indication of the range of possible

What are the reaction mechanisms for singlet oxygen in the atmosphere?
Earth scienceAsked by: Robby Filippi What process produces singlet oxygen? photosensitization In solution, the singlet oxygen is often prepared by a process called photosensitization. A photosensitizer is irradiated to its singlet excited state, followed by conversion (called intersystem crossing) to its triplet excited state. Why is singlet oxygen so reactive? Because of differences in their electron

Radius of Influence – groundwater pump well
Earth scienceAsked by: Widi Brady What is the radius of influence of the pumping well? In this work, the radius of influence of a pumping well is qualitatively defined as the maximum distance from the well up to which the influence of pumping is significant (Fig. 1a). What is the radius of influence? The “Radius of

Is it theoretically possible to artificially create amber?
Earth scienceAsked by: Widi Brady Yes, and this has been done since at least the mid 19th century (Răducanu, 2006) initially it was done to keep up with the demand, but now is a source of scrutiny for valuation of samples (Pederson and Williams, 2011; Răducanu, 2006). Imitations have been produced by heating the following (Răducanu,

How/where is randomness/stochasticity used in weather prediction
Earth scienceAsked by: Angie Davenport Which algorithm is best for weather prediction? Recurrent Neural Networks are the best way for multivariate weather forecasting or prediction. Neural network with data processing is suitable for weather forecasting. Neural network can take different features as input variables to find nonlinear relationship between input and output. How are simulators used
