When looking at the earth wind map, some lines clearly distinguish themselve and act as "frontier" between stream of wind. I was wondering what it was and what was causing them? Thanks.

It is true that there are multiple definitions of a continent. But it is also true that Europe fails to satisfy any of them. One of the boundaries between Europe and Asia was chose arbitrarily(the ...

I am curious how do mountain springs get their water. The water flowing from them eventually forms rivers. Is it only from rain and snow? Or does water also come from underground-below the mountain (...

I have a polygon line on earth's surface as an ESRI shapefile. For a point on that line I want to determine the geodesic that intersects the line orthogonally in this point. Are there suggestions on ...

e.g., Nitrogen solubility as high as near 25 ppm in forsterite, pyroxene, and garnet have been reported in an experimental study in the 1.5–3.0 GPa range with the oxygen fugacity controlled at those ...

I took a photo of an amazing sight I had never seen outside my home ( southern india ) but I could not tell if it was a rainbow type thing or an aurora borealis. Also if it was to be a sun dog , ...

I am working on CO2 and CH4 by WRF-CHEM, for providing my anthropogenic emission from Edgar data base, I'm going to use the Prep_chem_source App. I would like to use Edgar data emission (as my ...

These limestone-clay rocks are very common in the Alps, they come from weather changes. How many years does it take to make one of the rock bands? 7 years, equivalent to an el-nino type event? 1000 ...

The reason behind the non- formation of dewdrops on a cloudy night is the non-attainment of below dew point temperatures. It happens as the outgoing longwave radiation (OLR) is not allowed to escape ...

I was wondering whether you could help me with the following issue: I am running a negative binomial model (overdispersed) on count data of sampled insects at 22 sites. Here, I would like to select ...

In many articles online, geologists and geographers have described and depicted the theorized locations of all our continental plates with great detail and illustration, providing pictures, time-lapse ...

I am trying to understand how prevailing winds and jet stream currents are formed and how they are varying in speed and direction. When looking at different wind speeds at different altitudes on ...

Good afternoon. Inside the creation of the synthetic seismogram some softwares have the option to run what is called "sonic calibration" or "checkshot calibration". I have some questions: 1)why some ...
