Earth Science

What can you say about this subject? This is an assumption, but what could be the impact on the world?

Why is there so much more sodium than potassium in sea water? ca. 30 : 1.

Why are the directions of wind and current designated in an opposite way, as in "Northern wind" vs. "Northern current"?

Has anyone been watching the new BBC2 series Earth, presented by Chris Packham ? I wonder what you made of it ? I thought it had some new thought provoking ideas but found some thi ngs rather difficult to follow. It has not been clear what is established and what is hypothesis. The programmes jump backwards and forwards along the timeline so it is difficult to place material presented in context or connection with other material either in the series or elsewhere.

The title is pretty self explanatory. Seems like it may be a good idea to use the vast amounts of saltwater in the ocean for eliminating waste to the treatment plants, or maybe waste treatment could be looked at a little differently. Or even to have the option to take a saltwater shower sometimes might be a good, even saving fresh water usage even more. I wouldn't feel so bad pushing the flush lever if I knew the water were saltwater.

A seasonal sport, watching developing storms. This one, the #1 in the image, is quite close to the equator, but I bet it will miss us anyway.

Hey Forum, My last input for the time being, but here's a little more food for thought. I originally posted both of these as responses to solicitations on the NASA NSPIRES website, this was wasn't taken seriously, the other I abandoned after seeing how this one went. The title is basically as obvious as it sounds, the technology would ultimately be attached to a rocket as a payload, and planted on the moon. The basic concept behind this is to create a Universal timeframe in realtime for everyone on Earth. A lot of people are trying to do this with automatic watches, and this kind of works but it's not the entire picture. Also not everyone has enough mone…

You might know about unusual amounts of Sargassum appearing in Caribbean in recent years. Here, in the Southern Caribbean we also started to get it and it is not good at all. Here is how it looked this morning in a lagoon on the windward side of the island: I don't know details but guess that this phenomenon is a consequence of the climate change, which causes changes in water temperature distribution and currents. Any thoughts?

Possibly. But we know nothing about the earth's core. Therefore it would be impossible in our present state of knowledge to know what effect if any the moon might exert upon the earth's core. Any answer we might come up with to this question is purely speculative.

Hi. Read somewhere that explosions or collisions of stars created much of the minerals that traveled trough space until stroke earth creating the deposits mined today. Is it reasonable to believe all planets and moons that existed then and in the same neighborhood received a similar 'rain of imported' minerals/elements ? Can soil similarities among planets tell they were nearby at that time; and dissimilarities mean they were then far apart ?

I've dreampt up a speculative scheme for greening a desert. Do you think it would work? (or be cost effective?) You need a desert that extends right up to a significant sea or the ocean. Like lots of Australia, or Namibia etc. Australia would be the best to try it on. Imagine you set up a huge array of pumps along, for example, the Great Australian Bight. Connect the pumps to spray nozzles, and start pumping when there is an onshore wind. Adjust the jets for a spray that evaporates most of the water, before it falls back into the ocean. So basically, you are manufacturing water vapour, from sea water, with the salty residue falling back into the ocean. So…

I'm curious about the extraordinary biodiversity supported by oak trees. Do they serve as crucial habitats for specific species of birds, insects, or other wildlife? Have you witnessed any awe-inspiring symbiotic relationships that revolve around oak trees?

Does the shape of Antarctica ( being round shaped ) And its position that the center of that circular shape is approximately on the pole Does have anything to do with the rotational forces of the planet ? Thanx ..........

This was published recently on ScienceAlert. Found the link on the Fediverse. I am posting here under geology as I seems more appropriate https://www.sciencealert.com/in-an-incredible-first-scientists-have-discovered-whats-at-the-core-of-mars So posting as it may be of interest to geologists as One question if elements such as Sulfur have formed would that perhaps suggest that elements such as Nitrogen may also be or may have formed at some point ?

A most interesting piece of conservation by the RSPB (Royal Society for the Protection of Birds) at a small river in Cumbria, called Swindale Beck. For the benefit of non UK members, the RSPB owns some very important wildlife sites around the country and has promoted some innovative and imaginative successful conservation projects. But what they say about the river and environmental change is very interesting and encouraging. How 'rewiggling' Swindale Beck brought its fish back - BBC News

Could climate change be caused by the heat water (thermodynamics pollution) discharged by once-through cooled natural gas, coal and nuclear power plants that heated water is disrupting the ocean currents similar to the water pump in a car malfunctioning? Experimentally, increasing the 400 ppm CO2 (.04%) in a small glass greenhouse to 3,000 ppm (.3%) does not increase the temperature differential yet one would expect a 13° F temperature differential at the upper 3,000 ppm CO2 concentration. In the last 100 years, the atmospheric co2 has increased by 200 ppm which would result in a 1° F increase in the glass greenhouse for every 200 ppm increase in the co2 level…

I have been hearing about air pollution, global warming, ice calving, running out of fossil fuels in hundreds of years. In fact, a few hundred years is only a very short time in the hisotry of our earth and humanity. Is the world really doing something practical rather than endless meeting and discussion and putting off things? Just take global warming as an example, is there anything actually done to stop or even reverse the damage?

Im looking for an online tool that convert any given line in the spherical earth map to the Metacor map I searched alot but couldnt find any............has anybody got any info on this and could help ? Thanx.................

Do cultures that lived historically between the tropics * the Cancer & Capricorn..... mainly used the lunar calendar as in their point of view the Annual rise and fall of the sun was not that much straight forward ( rising up to being perpendicular and then tilting to the other side then returning back to perpendicular and then again tilting on the other side ) also they didnt have that much of seasons as well Thanx....

And why?

Would anyone care to hazard a guess and say why?

This phenomenon can be observed on the island where I live at sunset. From time to time, not often, maybe a few times a year. This image holds for a couple of minutes and then fades and dissipates. I think I know the answer, but I might be wrong. Pix from my porch:

Well how do you explain the high conductivity of different layers of the atmosphere? gravity would probably create layers of atmosphere that thin out in a sudden. Meanwhile the Earth's magnetic field is larger then its gravity field. Colder magnet's are stronger.

Is this covid 19 virus helping our environment in anyway? Certainly, countries in lockdown are having less cars on the road, as people are working from home...but is this having the effect of more heating and/or cooling in the home? My own state has fast-tracked building projects, such as a much needed second Airport. Is/will this fast-tracking lead to some disregard for certain protection and emission policies? Will we need to wait a couple of years to gauge any overall effect?

Hello, I want to know what is meant by unsustainable in the following context from a book called Microbiology: a very short introduction. Soils exposed by deforestation lack the physical structure, chemical composition, and indigenous populations of microbes needed to cultivate consecutive harvests of cereals and other food crops. Intensive grazing of cattle on deforested land is similarly unsustainable. Even in areas where soils are exceedingly rich, crop productivity falls without soil amendment with organic matter and inorganic fertilizers. is it related to the continuity Intensive grazing?
