Let us say a car pollutes 1m3 of air. Is that pollution attached to that specific air mass or will it fall to the ground or take its own path through the air, independent of the air it first polluted? ...

I am a little confused by the terms "regional" and "relative" in the sea level change context. Do the two words have the same meaning? Does the "regional MSL trend" in https://www.aviso.altimetry.fr/...

I'm note sure if it's an anthracite, augite, jet (lignite) or something completely different. I don't know where exactly i found it because it's from my old rock collection. I would appreciate your ...

According to the Wikipedia article on the species Homo floresiensis, the remains discovered in 2003 consist of unfossilized bones. I would assume that means they are still composed of the original ...

Recorded (or raw) and processed pre/post-stack seismic data (relative amplitudes) usually display a standard normal distribution, albeit with a very small amount of skewness. What would be possible ...

Does the reciprocity principle hold true in an anisotropic subsurface environment?

I have a NetCDF file (gridded data) with a landsea mask. I would like to determine, for the coastal grid-cells, what the orientation of the coastline is. I need to do this in order to calculate the ...

This rock was about 3-4 inches bigger than a basketball. When dropped it shattered into a couple large pieces and a lot of small ones. The inside was marbled yellow (almost like quartz); the marbling ...

An analogy I came up with is: Predicting earthquake strength and timing is like throwing a sheet of glass on the ground and predicting how many pieces it will break to and where they'll end up. Is ...

This IRIS tweet shows a video of siesmic waves from the recent M6.4 Earthquake in California rolling across the US. I've made a small GIF to give the idea but the "GIF" in the tweet shows the whole ...

North-hemisphere ice-shelf melts on summer and grows on winter. I would expect appreciable changes on sea-level between seasons, but sea-level looks equal on winter than on summer. Why doesn't sea ...

Earth rocks are frequently folded at surface. Folds in alternating layers of limestone and chert in Crete, Greece. Source: commons.wikimedia Are earthquakes the main mechanism ...

I have taken a thunderstorm case where I need to calculate indices but I am not getting any code related stability indices in Python language, the code is available in GRADS, NCL for me it's difficult ...

http://www.purdue.edu/newsroom/research/2010/100830FischbachJenkinsDec.html The link above talks about a research paper from Purdue University that the researchers had detected slight fluctuations in ...

I found the rock in the picture while visiting Pawnee National Grassland (Colorado, USA). The rock shows concentric circles on both sides. On one side these circles are very clear, on the other side ...

I can’t figure out what type of rocks these are I would like to create pigment out of them to make a watercolor want to make sure they are safe, one is brick red the other is more of a deep magenta, ...

This question is different from How would weather change on a tidally-locked terrestrial planet?. None of its answers answer my question. I think it's answer might even have wrong information as I ...

Past week, NASA announced Curiosity Rover measured 21 ppbv of $\small\sf{CH_4}$ on Mars. This week, NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever ...

Jetstreams move at an altitude of roughly 6-9km above the sea level. Since, it is moving at such a great altitude how could it have possible impacts on the land? And how will jetstreams that flow at ...

I'm aware that PDEs, linear algebra, numerical analysis and such are staples of most applied mathematical endeavors. I want to know if there are other areas of "higher" mathematics that have useful ...

In the subject: "Introduction to Chemical Geology", I have given the spatial symmetry groups. At present, I know the different symmetry operators: rotation axes, center of symmetry (or inversion), ...

I recently came over some numbers of GHGs released per energy in food produced, and the result is pretty flooring. I can see how animal-based food production is quite inefficient so let's ignore that ...

Today (July 5th, 2019 just before 8 pm KST), along the Han River in Seoul, the surface of the sun could be viewed with my naked eye (no protection needed), and this was safe on the eyes. It appeared ...

I'm not familiar with these kinds of data sets but I'm looking for some data for a project I'm working on. Essentially I would like multiple time series of seismic data from different stations over ...

I'm wondering by how much the gravitation effects, tides etc caused by the moon (and other energy such as moonlight IR) increase the surface temperature of the Earth. So how much warmer than the ...

If sea-levels rise, does the Earth's atmosphere extend to the same distance out to space, with the pressure increasing, or does it expand? If sea levels rose 10m, how much change would there be to ...

I'm trying to understand the atmospheric greenhouse effect. If CO2 absorbs lots of IR radiation emitted from the Earth's surface, does it not also shield the same wavelength radiation that is coming ...
