An earthquake swarm rattled the Salton Sea region of Southern California and the US-Mexico border over the weekend, with seismic activity reaching up to 4.5 magnitude, as reported by The Sacramento Bee.
Burgess noticed that the beginning of the mass extinction, as well as a jolt to the carbon cycle and abrupt climate warming, coincided exactly with a switch in the style of volcanic activity in the Siberian Traps. During the initial 300,000 years of
"A 6-metre fungus would be odd enough in the modern world, but at least we are used to trees quite a bit bigger," says Boyce. "Plants at that time were a few feet tall, invertebrate animals were small, and there were no terrestrial vertebrates.
The dramatic scene was caused by one of the Earth's grandest volcanic events. "Around 1.1 billion years ago," says Esther Stewart, a geologist for the Wisconsin Geological and Natural History Survey, "the continent we call North America start
Magma consists of rocks and crystals at varying stages of solidity-the more melted, or liquid, the magma is, the more likely a volcano is to erupt. Two large reservoirs full of magma exist beneath the Yellowstone Caldera-one that's about three
Most people are taught that petroleum is formed deep under the Earth over the course of millions of years and is derived from the remains of plankton, plants, and other biological organisms. This explanation is stated matter-of-factly on certain go
The breakthrough actually came about by chance, with a research team from the US and Canada originally studying the way arsenic leaches from a mineral called pyrite. These are also described as framboids, derived from the French word for raspberry, d
That's what an international team of researchers led by Professor Xiao-Ming Liu (University of North Carolina, Earth, Marine and Environmental Sciences), her PhD student Cheng Cao (now postdoctoral fellow, Nanjing University) and her former postdoc
