Can volcanos cause isostatic depression
Isostatic depression is normally associated with glaciation, but can other geologic processes result in similar behavior of the lithosphere? Especially, can the weight of a volcano cause the surrounding lithosphere to sink.

Why does New Zealand and cold countries have volcanoes?
I understand that volcanoes are caused by the heat that causes high intense pressure below the Earth's surface. This intense pressure gets released and causes magna which becomes hot lava to flow out from inside the Earth.
Why does it happen in New…

How to calculate specific humidity with relative humidity, temperature, and pressure
I know there is this question already How do I convert Relative Humidity into specific humidity
but I don't have ρws = density of water vapor (kg/m3) and ρ = density of the moist or humid air (kg/m3).
Is there another way to calculate it? Also I…

Evaporation loss formulas
A while ago I created a spreadsheet to calculate evaporation loss. I found several formulas to do that, two from Kevin Rafferty and one from Engineering Toolbox. The one from Engineering Toolbox was too convoluted, and I couldn't figure out how to…

Why do certain areas on Earth have a higher or lower air pressure at sea level?
For instance, looking at this map of world air pressure in January and this map of July, why do some land surfaces have a higher pressure during the winter?
I know that the tropics and Coriolis forces have something to do with the direction, and…

Does El Niño increase the amount of heat that escapes into space, or does it increase the amount of heat trapped on Earth?
So we know that surface air temperatures are warmer during El Niño events (which implies that there is more heat in the atmosphere, although maybe it's possible that it also means there's less heat in the oceans?).
I'm wondering... though.. Could…
