[ad_1] Scientists trying to figure out how and when volcanoes might erupt face a challenge: Many of the processes take place underground in lava tubes bubbling with dangerous molten Earth. At the time of the eruption, any underground markers that could have offered clues leading to an explosion are often …

[ad_1] Monash University geologists shed new light on Earth’s early history through their discovery that continents were weak and prone to destruction in their infancy. Their research, which is based on mathematical models, is published today in Nature. The Earth is our home and over its 4,500,000,000 (4.5 billion) year …

[ad_1] Methane, the main component of natural gas, is the cleanest fuel of all fossil fuels, but when it is released into the atmosphere it is a much more potent greenhouse gas than carbon dioxide. According to some estimates, the seafloor methane contained in ice formations along the continental fringes …

[ad_1] Four and a half billion years ago, the Earth would have been difficult to recognize. Instead of the forests, mountains and oceans we know today, our planet’s surface was entirely covered in magma, the molten rock material that emerges when volcanoes erupt. The scientific community agrees on this. What …

[ad_1] Mechanical engineer Michael Gollner and his graduate student, Sriram Bharath Hariharan, of the University of California, Berkeley, recently visited NASA’s John H. Glenn Research Center in Cleveland, Ohio. There, they dropped burning objects into a deep pit and studied how fire vortices form in microgravity conditions. The Glenn Center …
