The building blocks of life on Earth may have been fueled by tiny sparks hopping between water droplets.

The substance can contain up to 1.5 percent water, and if the ringwoodite under the surface has just one percent water in its ...

The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

Rivers on Earth carve winding paths through landscapes, shaping the terrain over time. At first glance, their meandering curves may seem similar to those formed by lava or ice. However, a new study ...

Water evaporates from ground level and rises into the atmosphere, spreading across the world as vapour before cooling, condensing and returning to the Earth as rain or snow. However, decades of ...

Much progress is possible. In fact, due to the dedicated efforts of governments and NGOs since the 1992 Earth Summit, safe drinking water has been made available to some 1.7 billion people around ...

Seafloor is made of a denser rock called basalt, which presses deeper into the mantle, producing basins that can fill with water. Except in the crust, the interior of the Earth cannot be studied ...

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...
