Earth Science

By protected I mean in the following sense: I'm mainly interested in whether the US has the more park space for it's citizens to enjoy...than Canada and most of Western Europe. But, the more information the better...if anyone has a link to a list or some data to share. I'll be forever grateful. I've been looking for months, all I can find is % and only the top 10 countries or something. (of which, US is not included, fyi) So, I'm interested in a comprehensive type listing for area. If at all possible. Or whatever... your opinions and conjecture would be cool, too. Thanks.

Have you ever seen the movie "True Lies" with Arnold Schwarzenegger? If you have, you might know why Im posting this thread, if you havent, heres why. In the movie, Mars is now inhabited by colonists from Earth and they live in oxygen supplied domes. Seems reasonable enough for a sci-fi flick. Then movie basically states that all of Mars's core is a giant glacier that, once undergoing sublimation caused by an alien reactor, will release so much oxygen and life-sustaining gasses that Mars will have an atmosphere suitable for human life. WTF?! This was more than far-fetched to me. I thought that if a planets glacial core went through sublimation…

I can only think that what I am working on is beyond the moderators of this forum to understand. My threads being locked by moderators such as yourself with no explanation does discourage innovation and invention. Am I to blame if a scientist does not understand that an increase in angular momentum also allows for an increase in the excitement of that body ? Very well accepted. It was a Russian who proved this in the 1950's. He used a body in space and a craft losing it's momentum. Proven to be true. If a satellite is slowing, a near pass to a celestial body will allow it to increases it's velocity which also increases it's kinetic potential. This is because the c…

1) What makes the difference if a soil will leach out completely or a soil where clay or other material illuviation will take place? 2) Why are podzolic soils acidic? 3) Why is there an upward movement of groundwater in arid areas (what causes this)? 4) Why is kaolinite often formed at the base of tropical soils? Thanks!

I seem to recall a prophecy by some AGW guys back in '08 that forecast the apocalypse in 100 months, is that still true? I am working on my bucket list just in case and it would be nice to know how to budget my time and funds. I want to say the countdown started in April but it could have been August. Eat, drink, and be merry!

Within an ordinary gust of wind there can can be a certain wind speed. But the gust of wind itself (as a whole) moves forward at much lower speeds. How does that work? What puzzles me the most is that you have fast moving wind that moves into slower moving air in front of it. Where does it go? The air pressure isn't so different inside a wind gust that you can explain this by compression phenomena (I guess?). The only thing I can come up with is that it works like a traffic jam ( to illustrate)? But in that video, you can see a compression, which we don't observe in a wind gust (or do we?)? My back-of-the-envelope calculations (mass balances) seem to fail. …

ok this one might be out of the realm of reality, but its also consists of both earth sciences and physics. im kinda curious on how it would happen if it ever could happen, in other words to theorize the concept. keep in mind i know enough to get me in trouble and im by far not a science guru. so here is the question ok now imagine the earth with climate change happening at a greater rate. now here is where it gets odd but rather interesting, the planet somehow exhibits a peltier effect, and instead of heating the planet it absorbs the heat and basically turns the planet into a refrigerator. now if you would entertain this thought and theorize about this. …

Hello, Something I’ve wondered about is those amazing air bubbles that are sometimes found in underwater caves. In particular, I was wondering how the depth of the water does or does not affects them. In my Figure 1 example, the water is 50 feet deep and air bubble in the cave has 3 feet of air from the top of the cave to the water, and the air pressure in the bubble is the same as sea level. Well, what would happen if the same cave was 1000 feet deep? (see Figure 2.) Would the bubble still have 3 feet of air from the top of cave to the water? Or would the tremendous weight of the water make the bubble much smaller like just 3 inches tall or something? And …

Those of you who have been kind enough to take an interest in my posts may have noticed that I am acutely aware of the limitations of renewable energy projects. In the past, however, I was quite a champion of these and in some ways maybe I still am. For example, wind energy would be better harnessed by the blade hub driving a crankshaft connected to an air compressor rather than a generator, particularly in an offshore application, where wave energy could be stored by the same means in submerged air tanks. This source of compressed air could be tapped at will to drive a turbine and render the power stored as dispatchable as hydroelectricity, helping the grid meet…

Hello, members. I've come across this science forum under a recommendation from some of my friends. I have still yet to see if your discussions contain viable content, regarding that I've only become a member recently. Moving on from that, I am an aspiring student who is interested in environmental problems that impact our world or countries socially, economically, etc. Right now, I'm focusing on the topic of weather modification (otherwise known as geoengineering physics) -- more specifically, cloudseeding. I have a google form with an article that summarizes my information, but I feel that it possibly needs more revision, or more areas to look into, like alterna…

Wouldn't you have loved to be there!

Hello to everyone reading this post I have a very simple question about gravity. We have seen planes flying at altitudes of around 35,000 ft. So if a plane takes of from Hongkong it will land in spain more quickly. And it will take more time if it travels form spain to hongkong. This is bcoz of the rotation of the earth from east to west. SO My question is if i happen to lift myself up in space by about say 2ft, will the earth pass by and say within a few hours spain will arrive automatically due to the rotation of the earth form east to west . And then i can land on the earth. so why use planes in a east to west travel..... or is there anything else.

I'm writing a research paper, and one of the conditions is that one of my resources MUST be an academic article from an academic journal. My topic is Paper Recycling. I have been googling for the past half an hour and have been unable to find one, perhaps im looking in the wrong places. Could anyone maybe tell me about a free online academic journal please. Thanx.

First, hello to anybody who remembers me from the .com and .org sites! It's been a while... Anyway, I see geologic time scale charts that look like this: and I want to create another one, but much longer so I can show more details. I've already gotten a binder and put pages in it to create a "book" timeline. Here it's opened to the page from 75 to 100 million years ago, with ages labelled. As in the first timeline, I want to put pictures of life that existed at the time. Does anybody know good resources that will give tell me what types of life existed at a given point in time, so I can find appropriate photos to put in there? I know I can look at the Wikipedia pages fo…

Hello all, Could anyone explain how to estimate the age of rocks (I have to age Granite if that helps). Thanks

Could ai be employed to track and predict the movements, numbers, points of the congregation during their migration, and the humane dispersal of climate refugees within western countries?

The sandy soil in the sand dune is dry and porous. I would like to know the air content 1 meter (3.3 ft) below the surface. How much the air is there?

I wonder if anyone has any ideas as to how one might figure this out. If there were a tunnel from one side of the earth, through the center of the earth, and on out the other side, what would the air pressure be in the center? I have some ideas, but one catch is that the air pressure and air density would seem to be mutually interdependent..

Hi everyone, Aerospace engineer here looking for input outside of my realm of expertise. I've read up quite a bit about home recommendations for air quality -- basically, the idea that a property is more at risk to asthma development/etc. for homes within 300 feet of a major freeway. My family is considering a home that is about 200 feet from an expressway (6 lanes across, stoplights, 45 MPH). The expressway is a major thoroughfare in the area that stretches across several suburbs in Silicon Valley. However, it doesn't see heavy backup at this area. So there's always some light volume of traffic going through but you don't get those endless bumper-to-bumper during…

Before 43 Mya, the Pacific oceanic plate was traveling northwards. Then, in a sudden shift, it began migrating northwestwards. This "jarring change in course" created a 'kink' in the Hawaii-Emperor volcanic island chain, erupted by the Hawaii Hot-Spot. Thus, before 43 Mya, only the Emperor islands existed; and, they 'trailed away', from the Hawaii Hot-Spot, in a northerly direction, at least as far as the Meiji sea-mount. And so, if, before 43 Mya, the Emperor islands extended even farther northwards, then the westerly motion, of the Pacific Plate, since that time, could have 'scraped off' those northern-most sea-mounts, onto the coast of Alaska, creating the Aleutian…

Hello all. I am trying to understand the difference between altitude and density altitude. The only difference is that density altitude depends on my position's current air temperature and altitude does not? If my position's current air temperature is increased, then the density altitude is also increased, but the altitude remains fixed. If my position's current air temperature is decreased, then the density altitude is also decreased, but the altitude remains fixed. I am right? According barometric formula of wikipedia (http://en.wikipedia.org/wiki/Atmospheric_pressure#Altitude_atmospheric_pressure_variation), the altitude depends on my position's current atmoshperic p…

How to identify the nature of amphibolite lenses within the marble? No alteration is observed along the boundary, except a thin dark coloured zone (baked margin?) along the amphibolite. At places, the amphibolite varies in the range of less than a cm to tens of cms. calcite lens are preserved within the larger amphibolite lenses.
