Seeing an article about how Chimborazo is the furthest point from the earth's center I started to wonder if the atmospheric density follows sea level of the gravitational center of the earth. My gut tells me that the air is thinner at the top of Everest but I'd really like to hear the science why that is or isn't the case. Local variations excluded it does seem that both the surface of the earth and the gravitational center have an effect on the forces acting on the atmosphere.

Now that I'm thinking about it there might be two different answers to two different questions; 1. Is the air thinner on Chimborazo or Everest (because of local environmental factors), and 2. Does the atmospheric density follow sea level or gravitational center?

As a geophysicist with expertise in shallow seismic surveys and well logging, I possess a strong background in geophysical data acquisition and interpretation. Additionally, I have developed skills in signal processing using Python and machine learning techniques. I am currently seeking opportunities in Europe and would appreciate guidance or leads on potential job openings that align with my expertise.

Usually, when talking about climate change, scientists say that we need stop emissions to reach that goal. That means leave the fossil fuels in the Earth's crust and don't burn them. That solution is clear. If you don't use fossil fuels, any potential carbon emission stays in the ground, so to speak.

Also, they argue that if emissions are stopped, planet heating will also stop. For heating to stop, excess carbon dioxide needs to go somewhere to reduce its content in the atmosphere. My question is, where does it go? Who or what is supposed to remove most of the excess carbon-dioxide from the atmosphere? It doesn't really get turned into fossil fuels or buried into the Earth's crust in the matter of few decades (this process takes millions of years).

Are we supposed to use technology to remove it out and effectively return to the ground? Are plants, forests and other photosynthetic organisms supposed to take it? If latter is the case, that brings additional questions as photosynthetic organisms also respire, returning carbon-dioxide into the atmosphere.

I assume if there is some kind of equilibrium here which doesn't lead to planet warming provided there are enough photosynthetic organisms to take this carbon-dioxide out of the atmosphere during photosynthesis.

Hence, the mantra: "Plant more trees"

ey people, I am doing a project about mars its atsophere. As many people know the atmosphere consists out of multiple layers. My question is how do we define these layers when they are not applied to earth? When I look it up it is usually defined by the temperature, hight and the sort of gasses that hang around the layers, yet earths atmosphere is heavely influenced by the ozon layer. How can we lable the layers of atmosheres that don't have an ozon layer. ( Some of the same layer lables are used in describing Mars' atmosphere yet I can not find why they are labled as such. ) If anyone has ideas for the reason that these layers were labled as such or knows where i can find them, it would be very cool

Hello. I’m looking for people who would be interested in joining a study group focused on super-earths and life. This is done through Harvard’s free online course program. Anybody interested and serious, I’d love to work together.

This is a 15-week course, I will create a discord group. PM or comment if you’re interested. Serious inquiries only please.

I’m a current Computer Science major, but I really enjoy Earth Science (I’ve taken the basic course sequence as part of my gen ed).

I’m wanting a minor that will be useful in getting a career, and am torn between business & ES.

I don’t particularly like business (I took the basic class for gen ed as well), but it won’t be too terribly challenging and I think is universally helpful.
I do like ES, especially mineralogy, but would have to take an additional chem course and a handful of upper divisions.

Is there much in the way of pathways for someone with & ES minor?

Hi. I'm trying to get clear on some ice age related terminology. My understanding is that there are ice ages and smaller glaciation periods within these ice ages. It follows that there are also intervals of time between ice ages and intervals of time between glaciation periods. I would like to know what the different terms are for a) the time intervals between ice ages, and b) the time intervals between glaciation periods. The internet (i.e. Google) can't seem to distinguish between these two types of intervals and would have you believe they're both called "interglacial periods". Is that true or are their different terms for these different intervals? Thank you for the help!

Training sessions will be available in English and Spanish (disponible en español).

Hi everyone! I am (22F) a master's student in Earth Sciences in my final year. I am currently thinking about what I would like to do in the future, and doing a PhD in glaciology seems a good option for me because I'm interested in glaciers, in particular, in remote sensing and mapping of them. However, I have a feeling that a career in academia may be not for me even though I am passionate about research. So my question is, is it possible to work as a glaciologist in industry? Thank you

Hello!

I have a specific question for this sub. I struggle to understand what makes different:

• Planetary boundaries
• Tipping points

Both of these concepts make references to thresholds.

I read the article of Rockstrom on this point, since I am not the only one to be confused about the difference. But it didn't help a lot event if I understood that not all planetary boundaries have tipping points, for example.

I could possibly figure it out myself if I read about their methodologies but it would take age...

Can someone help me?

Thank you very much.

I have recently graduated from The University of Manchester with a Master's degree in Earth Science, focussed around Geology and Volcanology. I am 22 years old and would be keen to hear some guidance on potential careers. Here are my main interests and current ideas:

• Love the idea of getting into Science Journalism but not quite sure how.
• Enjoy being in the lab, researching, and writing reports based on data findings. This was especially apparent when completing my big research projects in my degree.
• PhD in Volcanology.
• Working in the Volcanology field, considering volcano monitoring and hazard/risk management.

Let me know if you have any routes or connections I can explore for these pathways!

I’ve been appointed by my government to work in land regulatory and inspections for ministry of resources and environment. I want to become a geologist and was hoping I’d get in their geoscience department but sadly they put me in land management. Is this still related to my degree to further specialise as a geologist or have I strayed far from it?

Hey everyone, im currently a sophomore in a high school. Its currently the first marking period for me and i recently scored a bad score on my earth science test. Earth science is basically new to me as i forgot most of the stuff from past years.The test was on “prologue” and i would say my teacher is decent, my notes were pretty spot on with her lessons. Im a very last minute person so i studied the day before the test, reviewing my notes and just watching a video. I would say I studied around for an hour or a little bit more. The day of the test it just seemed like i only knew a quarter of the topic i learned, everything else was confusing to me. To be honest with my self i don’t think the way i study is good for me as reviewing notes doesn’t drill the information into my brain. So i need advice! Do i use any good websites? Quizlet? Khan academy if they have? Maybe chatgpt to study also? Any ways on how to study for earth science? Maybe more hours for studying or a tutor? Any advice is needed thanks!

Hey everyone! Currently learning about glacial and interglacial conditions of the Quarternary and it's got my brain thinking about all the what ifs in life. Humans have most definitely created an anomaly where we are in an interglacial period for much longer than previously recorded. Is a glacial period ever to occur again? What's your thoughts? 🤔

There are meromictic lakes (i.e. lakes containing layers of water that do not mix) which are freshwater from the surface to a certain depth (often one that no ordinary human would ever end up) but have a layer of saltwater at the bottom that never mixes with the upper layers. Examples of such lakes include Powell Lake in British Columbia, Green Lake in Upstate New York, and Lake Fidler in Tasmania. By definition, would these lakes be considered saline lakes, freshwater lakes, or something entirely different?
