In a paper published in the Februray 8 issue of the top scientific journal Nature, investigators at the Yale University showcase a scenario detailing how Earth's continents will rearrange themselves. We are currently right in the middle of a supercontinental cycle. Such a cycle usually lasts for hundreds of mill... |

A new study by investigators at the Massachusetts Institute of Technology (MIT) manages to reveal the intricate and ancient history of the North American craton, a section of our planet's crust that has been around for a very long time, and that lies right in the middle of the continent.
Earth's rocky lay... |

Rock samples collected from a series of African mines during a recent expedition indicate that the process of subduction is at least 2 billion years old, even if plate tectonics appeared (in their current configuration) just 1 billion years ago.
Large-scale continental movements are a trademark of the tectonic forc... |

Scientists with the French research agency CNRS in Paris, led by group leader and geophysicist François Pétrélis, have determined that plate tectonics may be responsible for the swapping of magnetic poles over intervals of millions of years. Plate tectonics is a term used to describe the slow and... |

The results of a new scientific study indicate that our planet indeed remains of the same size at all times. Researchers proposed some time ago that the world was contracting and expanding periodically, but the latest NASA-led investigation proved them wrong. Experts first proposed the expanding Earth hypothesis whil... |

Though jewelers can't stand them, impurities that develop in diamonds when the precious stones are formed are a treasure trove for science, because they hold clues as to how the Earth looked like hundreds of millions of years ago. If ancient minerals are trapped within diamond, then they will survive unaltered f... |

In a groundbreaking new research, investigators were able to determine the existence of a new, previously-unstudied force that acts on our planet's tectonic plates, leading to their interactions. This newly-found mechanism allows geologists and seismologists to gain a new perspective on the tectonic interplay ta... |

British researchers at the University of Leeds propose in a new study that the planetary core is undergoing two interesting processes at the same time. According to the data the experts obtained, it could be that the core is both freezing and melting simultaneously.Conclusions such as this, the team reveals, can be d... |

Researchers in the United States are now using Global Positioning System (GPS) measurements to gain additional insight into how oceanic tides are influencing the surface of the planet. The amount of stress they must place on Earth's crust is tremendous, scientists suspect, and GPS is here to help them.For most, ... |

When a 7.9-magnitude earthquake struck the Chinese province of Wenchuan on May 12, 2008, it devastated a very populous area, that was not at all prepared to deal with such a disaster. Now, eyewitness accounts are helping experts piece together what happened. Due to the large population density living in the area, man... |

A new research carried out by researchers at the University of Bristol in the Hudson Bay region in Canada, suggests that plate tectonics were inactive when our planet was younger and hotter.There are still many unknown things about the processes that gave Earth's crust its current shape, and the beginning of the... |

A new geological theory gives rise to the belief that our planet has two inner cores instead of one, as scientists believed until now. That's not to say that the new theory proved correct. In fact, it's very difficult to say what exactly lies at the center of the Earth, as studying the region is nearly impo... |

Scientists at Harvard University managed to expose a link between plate tectonics and the shifting atmospheric conditions that govern a certain region at a given time. They turned to the Andes Mountains, which, according to the study, were formed because the area turned from a lush forest into the desert we can see t... |

More than 500 fossils of teeth and bones belonging to species of rodents, horses, crocodiles and turtles found near the Panama Canal, dated to have lived as far as 20 million years ago could provide some information regarding the period when the North and South American continents became connected to each other, say ... |

Nearly 300 million years ago, the world's last known supercontinent, Pangaea, started breaking up, eventually forming the seven continents we see today. Heat radiating from Earth's molten iron and nickel core is released to the outermost layers of the mantle through convection, which can also be held respon... |

The molten rock inside the planet's mantle is in continuous motion as heat is convected from the inner regions towards the outer ones, forming the so-called convection cells where the hot material is being pushed upwards and the colder one falls back down in the vicinity of the core. The motion of this material ... |

Forty million years may seem a lot compared to a human life, but when it comes to the forming of a mountain range such as the Andes that's incredibly fast. A study published recently reveals that a typical mountain range could double its height in as little as two million years, a couple of times faster than sug... |

It's quite obvious that the Earth is going through a climate change that may have effects far more serious than a slight heating of the atmosphere. A prolonged heating, as a new study suggests, could bring our planet into a situation similar to that of Venus, whose crust became locked in place."The heat required... |

The previous model regarding Earth's interior put things very simply. The Earth is made up of several distinct layers sitting on top of each other. The first and outermost layer is the crust, spanning over 25 kilometers towards the center of the planet. Next comes the mantle, a thick, dense layer of silicate roc... |

Five hundred million years ago, the Earth had a single supercontinent, Gondwana, located in the southern hemisphere, but one hundred and eighty million years ago it suddenly split. Different pieces of Gondwana started moving apart from each other, thus creating the seven continents we know today. The mystery of why t... |

Although Mars doesn't look much like a planet ravaged by volcanic activity in the past, it is clear that it had to go through such a stage in its history. Now, new observations conducted with ESA's Mars Express spacecraft reveal the actions of lava flows and water on the surface, and how these molded the Ma... |

This may seem good news for people living in areas with increased seismic activity; however, it is anything but good. A new study involving the Earth past geological activity suggests that the plate tectonics could have come to a complete halt somewhere about 30 to 50 million years ago, and may do so in a distant fut... |

The search for planets outside the solar system ultimately resulted in the discovery of Earth-like planets, or super-Earth and they are generally rocky planets slightly bigger than our planet, so astronomers are speculating what the conditions on those planets might be like. Harvard scientists suggest that Earth-lik... |
