The water in your pond has to lower to below freezing. It takes time for the heat of the water to transfer to the surroundings. The ground underneath the water probably isn't below freezing either, so it will be transferring heat to the water at the same time. Looking at the temperature history for the time in question, the high temperatures for all the ...

In short, weird things happen when you combine things that don't combine in nature: the Earth is a perfect sphere the Earth is spinning on an axis Einstein's equivalence principle tells us that accelerations are all the same, no matter what's causing them. So you just add the acceleration vectors up. The (real) Earth has an equatorial bulge because a ...

If the Earth were a perfect ball, which it is not, and had a perfectly smooth and even surface with no basins or irregularities, water would tend to move toward the equator, where it would form a bulge. Meanwhile, gravity would be pulling on this bulge and trying to drag it down, thus preventing it getting any higher and stopping the flow of water into it. ...

I think what you mean by thermo-electric nitrogen fixation is the nitric oxides created by lightning discharges. This is absorbed by the raindrops as they form and as they fall to earth, and helps to fertilise the soil. You won't get this effect with sprinkler irrigation to any great extent, because the water droplets are exposed to the nitrogen oxides for ...
