The sample had between 20% to 30% of a type of clay called smectite, which forms in the presence of water, Blake said.
Because most of the peninsula sits on a limestone shelf, there are no surface rivers, and rainwater quickly seeps underground where it gathers and forms subterranean bodies of water known as cenotes.
Irresponsible industrial practices have wrought terrible environmental abuses in forms of air, land and water pollution.
The widespread adoption of water mills on a scale never seen in Roman times led not only to a wider range of uses for water power, but an increase in other forms of mechanisation.
Wind and rooftop solar panels, meantime, are the most efficient forms of generation when it comes to water.
FORBES: Water Shortages May Leave Energy Producers Dying of Thirst
This international review of participatory water governance forms an important resource for academic researchers in hydrology, environmental management and water policy, and also practitioners and policy-makers working in water management.
More impressively, the cichlid fishes of Lake Victoria have generated 500 forms in about 14, 000 years (lakes are islands of water).
WSJ: Matt Ridley on the Possible Formation of a Species | Mind & Matter
And the melt water forms an essential part of many of the world's major rivers.
The seawater down there is so cold that when natural gas bubbles out of the well into the water it forms methane hydrates, which clog the uptake pipe.
FORBES: BP's Big Box Removed From Leak As Gas Crystals Clog Uptake Pipe
In the ancient oceans, green rust's ability to pull nickel out of the water would have been critical for some life forms, since nickel is an important nutrient for microbes that produce methane.
The paperback is being made temporarily available at deep discount to support a world class charity, Charitywater, which quietly is solving a problem that kills more people than all forms of violence, including war: the lack of clean and safe drinking water.
FORBES: Dave Logan Explains Where History And Miraculous Innovations Are Made
They are a pretty basic technology, they are a one hit, while if we develop lagoons, if we develop other forms of tidal and wave and other ways of extracting the energy from the water and the wind then I think we've got a great potential export trade.
Sensors near Trent's cameras will show how hot the conditions are near multi-celled life forms to make sure they are found in extremely hot rather than jets of cooler water.
Like the other forms of industrial fishing, longlines, some of which submerge thousands of hooks in the water, yield immense quantities of bycatch, or unwanted fish, most of which is severely injured or dead.

Volcanic obsidian forms the island's spectacular cliffs and grottos, and since access to fresh water has always been of prime concern, the indigenous houses, or dammusi, were brilliantly conceived back in the 10th century with domed roofs designed to channel rainwater into adjoining cisterns.
Micro-organisms on Earth are much more common in fresh water than acidic water, and so rather than Mars just having been a potential haven for some extreme forms of life, Curiosity's discovery means that Mars had -- and still preserves evidence of -- environments that were habitable for an enormous variety of micro-organisms that thrive on our own planet.
