The oceans accumulate all the elements dissolved from the land and from reaction with the deep ocean floor at hydrothermal vents, such as spectacular black smokers. But only the water molecules themselves keep on cycling back to clouds—the elements are left behind. Some elements get so concentrated in the ocean that they turn back into minerals and fall out as sediments, notably limestone calcium carbonate and cherts silica , a process which limits their concentration in the sea. Unlike most elements, however, the elements sodium or chlorine—the two ingredients of salt—only fall out from the ocean episodically and in exceptional circumstances. For example, the entire Mediterranean dried up to a puddle about 6 million years ago, leaving huge salt deposits. This leads to a rush of elements and carbon into the oceans—which in turn speeds up the formation of sediment. This locks additional carbon dioxide into limestones, thus resetting the planet to its previous conditions and stopping everything from overheating. How do you think weathering works to stop the Earth completely freezing over? This is the key to initiating life. Down in the oceans, harmful radiation was filtered out, and the seas provided buffering against extreme temperatures and protected the development of life against bombardments of meteorites and intense volcanic outpourings.

The increasing success of microbes created more chemical byproducts notably oxygen in the atmosphere , most of which were initially toxic.

As long as the oceans have been present, they have always been slightly alkaline—perfect for making skeletons. But we—and future generations on Earth—face a growing problem. The booming of mankind and our thirst for fossil fuels is adding carbon dioxide—hence acidity—to the ocean at an unprecedented rate. In a million years or so, the dissolution of the land masses of our continents will accelerate sufficiently to start to neutralize this great burp of carbon dioxide into our waters. But this weathering is inherently slow, so in the meantime, the oceans are becoming a bit less alkaline and a bit less saturated. This process is often termed ocean acidification.

[PDF] [EPUB] George and the Blue Moon Download Water is even better at dissolving things if it is made a little acidic, by reacting with something like carbon dioxide to make carbonic acid. Take a sip of sparkling water those bubbles are carbon dioxide and see if you can taste the acidity; both my sons wrinkle their noses on doing so. Now, when water cycles from the oceans to clouds, then to rain and down rivers, it becomes a bit acidic by reacting with carbon dioxide in our atmosphere. As a result, this carbonated rainwater dissolves elements out of the land this is called weathering , takes them into the rivers, and the elements end up going into the oceans. Have you ever seen reddish-brown rivers? These are full of iron that has been leached out of the rocks.

Start your review of George and the Blue Moon. Apr 06, Aryan Mahesh rated it it was amazing. From a black hole rescue mission to old revenge stories to stopping a maniac from sending unsuspecting humans onto the surface of an icy celestial desert, the series has it all. The series was written by one of the greatest minds of the century-Stephen Hawking-along with his daughter Lucy Hawking. Before I give you a summary, I suggest reading the earlier books in the series. George and the Blue Moon is about George and his best friend Annie unknowingly trying to stop their old enemy, the maniac Alioth Merak from sending unsuspecting humans on to the blue moon, Europa. George and Annie register for a space training program which trains fourteen year olds for a future Mars missions. But when they get there they notice that the staff seem like they are hiding something. The strangest thing was their manager Rika Dur who seemed to be acting a bit odd. The book contains more than just a sic-fi story.
