I'm studying a migmatite with two overprinting fold structures. The first (Dn+1) is tight and the second (Dn+2) is gentle. Would it be fair to assume that, since Dn+1's tightness is, well, tighter, ...

In Colombia, many grassy hillsides are terraced, like in the photo below. This terracing also occurs on hillsides that never had these palm trees on them. I assume that it also occurs outside of ...

Surface mining digs up a lot of earth and rock. After the desired ore is separated, where do the earth and rock mined go?

I've been reflecting on climate change and pondering how much of it is truly man-made. Anyone who's shoveled a walkway know that the snow melts faster beside the walkway than it does in the middle of ...

What causes different locations to get their peak season for thunderstorms at different times of the year like some locations get the most thunderstorms in a July some in June and some in August and ...

I have repeatedly heard from various car enthusiasts that start stop technology has no benefit (or the tiniest smallest negligble benefit) to air quality so they turn it off entirely. Does it have an ...

I think the title says it all...

Does precipitation increase or decrease as elevation increases? Because I heard that in the mountains they get more precipitation due to the orographic effect and how the mountains drain the moisture ...

How is that a general rule of thumb that less humidity equals more rain? Deserts don’t get much rain and humidity is also very low. Rainforests get a lot of rain when the humidity is very high so how ...

Geothermal cooling has been an attractive option in the U.S. Northeast since it emits very little carbon into the atmosphere compared with compressed refrigerant systems which use lots of electricity....

In many articles in internet (I'm citing a couple for the sake of the question) , smokes from the fires (composed mainly of CO2 and CO) following a nuclear war would cool the atmosphere and would ...

Usually the higher the humidity the more rainfall we get like in the summer here in Asheville, North Carolina we get a lot of showers and thunderstorms in the summer from the high humidity but I saw ...

So there's a NASA satellite called SMAP currently orbiting Earth right now, and it can measure soil moisture, and detect whether or not soil is frozen or thawed. It knows this since it uses radar to ...

We hear a lot about positive feedbacks when it comes to global warming. For example: ice reflects solar radiation, so as the ice melts more solar radiation is absorbed which accelerates warming; ...

I encounter both similar terms while reading, isotherms and isotheres. Could someone help distinguish and explain to me the difference between them?
