  1. Researchers Look at the Origins of Plate TectonicsThe mystery of what kick-started the motion of our earth’s massive tectonic plates across its surface has been explained by researchers at the Univ. of Sydney."Earth is the only planet in our solar system where the process of plate tectonics occurs," said Prof. Patrice Rey, from the Univ. of Sydney’s School of Geosciences. "The geological record suggests that until three billion years ago the earth’s crust was immobile so what sparked this unique phenomenon has fascinated geoscientists for decades. We suggest it was triggered by the spreading of early continents then eventually became a self-sustaining process."Read more: http://www.laboratoryequipment.com/news/2014/09/researchers-look-origins-plate-tectonics

  5. Advertisement Few, If Any, Big Impact Craters are Undiscovered on Earth

    It is likely that most of the large impact craters on Earth have already been discovered and that others have been erased, according to a new calculation by a pair of Purdue Univ. graduate students.

    "Over the past 3.5 billion years it is thought that more than 80 asteroids similar in size to, or larger than, the one which killed the dinosaurs have struck the Earth, leaving behind craters which are over 100 kilometers across, but our model suggests only about eight of these massive craters could still exist today," says Timothy Bowling, a graduate student in Purdue’s Department of Earth, Atmospheric and Planetary Sciences. "Geologists have already found six or seven such craters, so odds are not in the favor of those hoping to find the next big crater."

  7. Evidence Supports Existence of Oceans of Water in Earth

    Researchers from Northwestern Univ. and the Univ. of New Mexico have reported evidence for potentially oceans worth of water deep beneath the U.S. Though not in the familiar liquid form — the ingredients for water are bound up in rock deep in the Earth’s mantle — the discovery may represent the planet’s largest water reservoir.

    The presence of liquid water on the surface is what makes our “blue planet” habitable, and scientists have long been trying to figure out just how much water may be cycling between Earth’s surface and interior reservoirs through plate tectonics.

  9. Pangaea’s Mountains Helped Earth Avoid Warming Last TimeGeochemists have calculated a huge rise in atmospheric CO2 was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangaea. This work is being presented to the European Association of Geochemistry’s Goldschmidt geochemistry conference.Around 300 million years ago, plate tectonics caused the continents to aggregate into a giant supercontinent, known as Pangaea. The sheer size of the continent meant that much of the land surface was far from the sea, and so the continent became increasingly arid because of a lack of humidity. This aridity meant that rock weathering was reduced; normally, a reduction in rock weathering means that CO2 levels rise, yet in spite of this CO2 levels – which had been falling prior to the mountain formation- continued to drop, eventually undergoing the most significant drop in atmospheric CO2 of the last 500 million years. This phenomenon has remained unexplained, until now.Read more: http://www.laboratoryequipment.com/news/2014/06/pangaea%E2%80%99s-mountains-helped-earth-avoid-warming-last-time

  11. Researchers: No Limits to Human Impact on CloudsUnderstanding how clouds affect the climate has been a difficult proposition. What controls the makeup of the low clouds that cool the atmosphere or the high ones that trap heat underneath? How does human activity change patterns of cloud formation? Now, the research of the Weizmann Institute’s Prof. Ilan Koren suggests we may be nudging cloud formation in the direction of added area and height. He and his team have analyzed a unique type of cloud formation; their findings, which appeared recently in Science indicate that in pre-industrial times, there was less cloud cover over areas of pristine ocean than is found there today.Read more: http://www.laboratoryequipment.com/news/2014/06/researchers-no-limits-human-impact-clouds

  13. Scientists ID Echoes of Ancient Earth

    A group of scientists believe that a previously unexplained isotopic ratio from deep within the Earth may be a signal from material from the time before the Earth collided with another planet-sized body, leading to the creation of the moon. This may represent the echoes of the ancient Earth, which existed prior to the proposed collision 4.5 billion years ago. This work is being presented this week at the Goldschmidt conference, cosponsored by the European Association of Geochemistry.

    The currently favored theory says that the moon was formed 4.5 billion years ago, when the Earth collided with a Mars-sized mass, which has been given the name “Theia.” According to this theory, the heat generated by the collision would have caused the whole planet to melt, before some of the debris cooled and spun off to create the moon. Now however, a group of scientists from Harvard Univ. believe that they have identified a sign that only part of the Earth melted, and that an ancient part still exists within the Earth’s mantle.

  21. Earthly Experiment Demonstrates Effect Seen in Space

    Streaming jets of high-speed matter produce some of the most stunning objects seen in space. Astronomers have seen them shooting out of young stars just being formed, X-ray binary stars and even the supermassive black holes at the centers of large galaxies.

    Theoretical explanations for what causes those beam-like jets have been around for years, but now an experiment by French and American researchers using extremely high-powered lasers offers experimental verification of one proposed mechanism for creating them.

    Using satellite imagery to monitor which volcanoes are deforming provides statistical evidence of their eruption potential, according to a new study led by the Univ. of Bristol published in Nature Communications.

    ESA’s Sentinel satellite, launched this week, should allow scientists to test this link in greater detail and eventually develop a forecast system for all volcanoes, including those that are remote and inaccessible.

'Geologic Clock' Helped Determine Moon’s AgeAn international team of planetary scientists determined that the Moon formed nearly 100 million years after the start of the solar system, according to a paper published today in Nature. This conclusion is based on measurements from the interior of the Earth combined with computer simulations of the protoplanetary disk from which the Earth and other terrestrial planets formed.The team of researchers from France, Germany and the U.S. simulated the growth of the terrestrial planets (Mercury, Venus, Earth and Mars) from a disk of thousands of planetary building blocks orbiting the Sun. By analyzing the growth history of the Earth-like planets from 259 simulations, the scientists discovered a relationship between the time the Earth was impacted by a Mars-sized object to create the Moon and the amount of material added to the Earth after that impact.Read more: http://www.laboratoryequipment.com/news/2014/04/geologic-clock-helped-determine-moon%E2%80%99s-age
