Why Volcanic Eruptions Can Spark LightningAlexandra WitzeScience News
Small volcanic eruptions (the ones we're used to, even dramatics examples, likeMount St. Helens' 1980 eruption) are typically triggered when molten magma burbles up from deep within the Earth into the volcano's magma chamber,explains Alexandra Witze forNature. This causes an increase in pre...
C WHY DOES THE OCEAN HAVE WAVES?The ocean is never still. Whether observing from the beach or a boat, we expect to see waves on the horizon. Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. ...
“Our results imply that all basaltic systems on Earth have the potential to produce powerful explosive eruptions.”— Dr Fabio Arzilli Dr. Arzilli said; “We found that, under certain conditions consistent with highly explosive eruptions, crystallization can occur within a couple of minutes during...
physicists have long puzzled over why sand grains and other small particles can build up electrical charges as they collide with one another, sometimes to the point of discharging lightning in dust storms or plumes of volcanic ash. now, a paper in an upcoming issue of nature physics suggests ...
New discoveries are changing long-held views of the biggest, meanest, and most bizarre animals that ever flew.
But while would-be holiday makers are naturallyupsetat having their plans disrupted, it's worth remembering it's not safe to fly planes through volcanic ash. So, how do airlines decide it's not safe to fly when a volcano erupts? And why is volcanic ash so dangerous for aircraft, anyway...
And we have rock samples from the Bedout High. Some apparently have extraterrestrial origin. I mean, they show the effects of extreme temperatures and pressures, the level of extremes produced only by an impact. And as for their age, well, they do in fact, date back to about 250 million...
The country sits on this earthquake belt and experiences both quakes and volcanic eruptions. Can earthquakes be predicted? We know which areas are likely to have lots of earthquakes, and scientists can even identify faults where large quakes have happened in the past and might happen again. ...
