Earth is eating its own oceans - guohua - 11-16-2018 Quote:The Earth is eating its own oceansIs This About!!!??? I'm waiting for Al Gore to make a Statement that Climate Change is Causing EarthQuakes and Volcanoes and that it is our Fault The Oceans are Slipping beneath the Tectonic Plates!! Quote:As Earth's tectonic plates dive beneath one another, they drag three times as much water into the planet's interior as previously thought.Ok,, let me get this straight in my head,,,,,as the plates slip below the other plate it drags or absorbs ocean water with it. Is there Room? Is there as space there for water to seep through? Is there a suction type action? No. Their answer it this. Quote:Water is stored in the crystalline structure of minerals, Shillington wrote. The liquid gets incorporated into the Earth's crust both when brand-new, piping-hot oceanic plates form and when the same plates bend and crack as they grind under their neighbors. This latter process, called subduction, is the only way water penetrates deep into the crust and mantle, but little is known about how much water moves during the process, study leader Chen Cai of Washington University in St. Louis and his colleagues wrote in their new paper.Ok, So just how much water do you think goes under our feet? :smalleyeroll: Quote:The researchers observed such slowdowns deep into the crust, some 18 miles (30 km) below the surface, Cai said.Three Billion WHAT!? Is Al Gore going to start announcing we are Draining our Oceans???? Oh, a they are talking about kilograms, that's not so bad is it? Quote:Seawater is heavy; a cube of this water 1 meter (3.3 feet) long on each side would weigh 1,024 kilograms (2,250 lbs.).Holy-Shit Batman,,,, That is a Lot Of Water!!!!!! Where is it all going? Does it come back? Quote:And that raises some questions: The water that goes down must come up, usually in the contents of volcanic eruptions.OK, there is No Missing Water in our Oceans,,,,, That means Old Al Gore Can Just Go Set Down and Play With Himself. Unless of-course he wants to say that the missing water is replaced by our melting Ice Caps. So, what do you think? RE: Earth is eating its own oceans - BIAD - 11-16-2018 There's a complex and scientific name for it. Nature. RE: Earth is eating its own oceans - gordi - 11-17-2018 The level of the oceans isn't changing because all of the Billions of Billions of Kilograms of water is being replaced with an exactly equal amount of plastic waste. Do your bit for the ocean - use non-recyclable plastic and dump it in a river or beach today! RE: Earth is eating its own oceans - 727Sky - 11-17-2018 Quote:(Phys.org)—A team of researchers affiliated with several institutions in Japan and Germany has found evidence that suggests the middle of Earth's mantle holds as much water as the planet's oceans. In their paper published on the open access site Science Advances, the group describes their theory and their experiments to try to prove them correct. RE: Earth is eating its own oceans - OmegaLogos - 11-17-2018 Explanation: @guohua ... Quote:Ok, So just how much water do you think goes under our feet? I did some maths and physics and came up with the following ... 3,000,000,000 teragrams = 3 x 100km^3 1,000,000,000 teragrams = 100km^3 1,000,000 teragrams = 10km^3 1,000 teragrams = 1km^3 (1000m^3 of water = 1 billion tons of water = 1000 teragrams) 100m^3 of water = 1 million tons of water = 1 billion grams = 1 teragram 10m^3 of water = 1,000 tons of water = 1/100th of 1 teragram 1m^3 of water = 1 ton of water = 1/10,000th of 1 teragram 10cm^3 = 1000 grams (1 kilogram , 1 liter, 1000 mls) 1cm^3 = 1 grams (1milliliter) 1mm^3 = 1 microgram (1micromilliliter) Therefor ... 3,155,760,000 teragrams / 1,000,000 yrs / 365.25 days / 24 hrs / 60 mins / 60 seconds = 3,155,760 teragrams / year = 8.64 teragrams / day = 0.36 teragrams / hr = 0.006 teragrams / min = 0.0001 teragrams / sec 1,000,000 tons x 0.0001 teragrams = 100 tons 10^2 x 1m^3 = 100 tons of water per second is subducted [eaten] by the earth / along a 50,000+km long subduction zone [total] = 2 kilograms (2 liters) / km = = 2 grams / meter = 20 micrograms (20 micromilliters) / mm / sec . Imagine a trench 50,000+km long and about 1mm wide and 660km deep, right along where the continental/ oceanic slab is subducting, and that 1mm wide gap allows a 2cm (20mm) tall 1mm^2 thin tower of water to soak/sink/seap/subduct into it per second, for every 1 mm along its entire length, nonstop for 1 million years ... that adds up to 3,000,000,000+ teragrams = 3.? x 100km^3 If we take that the ocean is 5km deep on average and that requires {20 x 5km slices of ocean} then 1 slice = 100km x 100km^2 = 100km^3 x 3.? = 60 x 5km slices of the ocean each 100km^2 in area = 800km^2 x 5km deep [64 x 100km^2 slices in 8 x 8 grid] and that takes up this much of the ocean ... Here is a map of subduction zones world wide ... Here is where I got my information on how long the subduction zones are ... Mapping giant earthquake potential (australiangeographic.com.au) Quote:There are 23 active subduction zones around the world. The total length of all subduction zones on Earth is about 50,000km and only about 10 per cent of this total length has produced giant earthquakes in the past 100 years, Here is where I got my guestimate for how deep the ocean is ... Ocean Depth (oceanservice.noaa.gov) I used MSCalculator in scientific mode to do all my calculations. Personal Disclosure: Firstly some music to go with ... I hope my maths and my data sources help put this into some kinda of back of the envelope and inside the ball park dimensions. Firstly 1 million years is a very long time and 2ndly 50,000km of subduction zone x 1mm wide is a big area = 225m^2 x 660km deep [aka thats a VERY BIG HOLE in total] Little things add up quickly over long ranges of space and time and I can easily see these figures as being close to accurate! HOWEVER I suck at maths and can be ORDERS of MAGNITUDE out ... so please don't rely on the above maths to do anything with unless you double check my results yourself first. And yet in comparison the 800km^2 x 5km deep ocean patch that is eaten by the earth every million years seems to pale into insignificance when faced with the great pacific ocean and or even all the rest of the oceans together!!! How much water on earth? [livescience.com] Quote:If Earth was the size of a basketball, all of its water would fit into a ping pong ball. So 3,200,000 cubic kilometers [800 km x 800 km x 5 km] versus 1,332,000,000 cubic kilometers [16,300 km x 16,300km x 5km] = 0.25% (1/400th) of the total of earths water is subducted over 1 million years. It is amazing what a 50,000+km long 2cm tall 1mm thick ribbon of water adds up to [100tons] and to think that we are 'losing' that into the inner earth every second is quite profound and amazing! RE: Earth is eating its own oceans - Wallfire - 11-17-2018 The maths in this is so far outside my comfort zone, I think I will just sit in the corner and suck my thumb RE: Earth is eating its own oceans - guohua - 11-17-2018 @"OmegaLogos" That Math made my Head Hurt WOW I've talk to people who have homes so close to the Ocean they can walk to it, They say the Oceans are not receding or rising. It looks the same level it did 20 years ago, they are not losing or gaining beach front property. But then I have read about this occurrence of bubbling mud in California on or near the San Andreas Fault line. Quote:A Gurgling ‘Mud Pot’ Is Crawling Across Southern California Quote:At the southern end of the San Andreas Fault in California, where the North American and Pacific tectonic plates famously touch, sits a stinky, gurgling pool of mud. Scientists have been aware of this “mud pot,” as the geothermal feature is known, since the 1950s. But it has recently become a cause for concern because, as Robin George Andrews reports for National Geographic, the mud pot is on the move. Does the action of the San Andreas Fault drawing water from the Pacific Ocean have anything to do with this? Can the Scientific Community put Two and Two together here? Or maybe it has nothing to do with Ocean Water At All. |
