Why does the meandering pattern of the jet stream itself propagate?
Earth ScienceAsked by: Jeremy Whiteman Why does the jet streams have a meandering tendency? Sometimes, like in a fast-moving river, the jet stream’s movement is very straight and smooth. However, its movement can buckle and loop, like a river’s meander. This will slow things up, making areas of low pressure move less predictably. The jet stream
Where did the atmosphere’s nitrogen come from?
Historical AspectsWhere Did All That Nitrogen in the Air Come From, Anyway? Okay, so you breathe in, you breathe out. Seems simple, right? But have you ever stopped to think about what you’re actually breathing? A whopping 78% of that air is nitrogen – an odorless, colorless gas that, honestly, doesn’t seem like it does much.
Has irreversible global warming already begun?
Earth ScienceAsked by: Tammy Peters The effects of human-caused global warming are happening now, are irreversible on the timescale of people alive today, and will worsen in the decades to come. How many years until global warming is irreversible? There is some indication the system has experienced a gradual weakening over the past few decades, and
How to sample for K-Ar dating?
Earth ScienceAsked by: Crystal Jones What kind of samples are required for potassium-argon and argon argon dating? The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes. How is K-Ar dating done?
Are there pockets of liquid carbon dioxide in Earth’s oceans?
Earth ScienceAsked by: Crystal Jones Quick answer is no, however there are methane clathrates somewhere down there and possibly also carbon dioxide clathrates as well. How much CO2 is trapped in the ocean? While previous estimates put the ocean sink at around 2bn tonnes of CO2 per year, we find that it could be 0.8-09bn tonnes
Lanes of flat ocean surface in coastal waters
Earth ScienceAsked by: Aaron Zilla What are the lines on the surface of the ocean? These patches are actually called windrows, and they are usually parallel lines of “stuff” sometime stretching for more than a kilometer. In our waters they are composed largely of sargassum, foam/bubbles, and a mixture of floating polyfoam, plastic, and other jetsam
