April Flowers for redOrbit.com - Your Universe Online The contours of the Earth's crust are influenced by the high temperatures deep within the Earth's mantle, according to a new study published in Science. A team of researchers, led by Brown University, demonstrated that those temperature differences control the elevation and volcanic activity along mid-ocean ridges, the colossal mountain ranges that line the ocean floor. Forming at the boundaries of tectonic plates, mid-ocean ridges...

Moon-Forming Impact Dated
2014-04-03 04:49:12

redOrbit Staff & Wire Reports - Your Universe Online Using a new method for estimating the moon’s age, an international team of planetary scientists has determined that the satellite formed nearly 100 million years after the formation of the solar system, according to research published Thursday in the journal Nature. The study authors came to that conclusion based on measurements from the Earth’s interior, as well as computer simulations of the protoplanetary disk from which...

Researchers Develop New Model Of Earth's Dynamic Interior
2014-03-31 14:24:13

[ Watch The Video: Researchers Develop New Model Of Earth’s Dynamic Interior ] Nikki Cassis, Arizona State University Seeking to better understand the composition of the lowermost part of Earth’s mantle, located nearly 2,900 kilometers (1,800 miles) below the surface, a team of Arizona State University researchers has developed new simulations that depict the dynamics of deep Earth. A paper published March 30 in Nature Geoscience reports the team’s findings, which could be...

Angelic Bakehouse, a leading producer of fresh sprouted whole grain products, has launched its newest product, Flatzza™ crust, with hopes to catch consumers who are focused on convenience. Taking a play on words between flatbread and pizza, the bakehouse is introducing this nutritionally-superior, great-tasting, ready-made crust to a category that typically is found on the bottom of the nutrition pile. Cudahy, WI (PRWEB) February 24, 2014 Pizza? Flatbread? What do you call the...

Australian Rock Determined To Be Oldest Material Formed On Earth
2014-02-24 13:04:03

[ Watch the Video: The Oldest Rock On Earth ] Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature Geoscience, say a rock in Australia is helping to paint a picture of how our planet became habitable 4.4 billion years ago. The team found data from a tiny fragment of zircon that confirms the Earth’s crust first formed 4.4 billion years ago, which is just 160 million years after the formation of the Solar System. John Valley,...

Dense Earth Crust Was Recycled Into The Mantle During Archean Eon
2013-12-31 07:31:36

redOrbit Staff & Wire Reports - Your Universe Online The temperature of the Earth’s mantle during the Archean eon some four billion years ago was significantly higher than it is today, causing the crust to become unstable and drip back down into the mantle, according to research published this month in Nature Geoscience. As part of the study, Dr. Tim Johnson of the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU) and his colleagues created model calculations...

Geoscientist Leads International Drilling Mission To Lower Crust Of Pacific
2013-12-04 11:33:49

University of Houston A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean. Co-chief scientists Jonathan Snow from UH and Kathryn Gillis from University of Victoria in Canada led a team of 30 researchers from around the world on the $10 million expedition, finding a few surprises upon...

Meteorite Reveals Martian Secrets
2013-11-21 07:06:46

April Flowers for redOrbit.com - Your Universe Online A new study has uncovered what may be the first recognized example of ancient Martian crust. The findings, published in Nature, are the work of Munir Humayun of Florida State University. His work is based on an analysis of a 4.4 billion-year-old Martian meteorite unearthed by Bedouin tribesmen in the Sahara desert. The rock, designated NWA 7533, might be the first recognized sample of ancient Martian crust and holds a wealth of...

Moon Gets New Face GRAIL
2013-11-11 08:26:13

[ Watch the Video: Man In The Moon Got His Looks From Asteroids ] redOrbit Staff & Wire Reports - Your Universe Online Scientists have long believed that the moon’s trademark craters were created from the impact of massive asteroids, but new research appearing in the journal Science suggests that smaller planetoids might actually have been responsible for pummeling the lunar surface. The lunar craters were believed to have been created approximately four billion years ago,...

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

redOrbit Staff & Wire Reports - Your Universe Online By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated. According to UPI, the researchers recreated the conditions of the Earth approximately 4.5 billion years ago, when much of the world was molten and the crust formed as lava cooled. Their goal was to develop a...

Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
