Mount St. Helens Geology: Back Side of the Volcano

When a meteor enters Earth’s atmosphere, it’s traveling at tens of thousands of miles per hour. The intense speed causes the air in front of it to compress and heat up to thousands of degrees. This heat is what makes the meteor glow so brightly, creating the streak of light we call a “shooting star.” As the meteor continues its fiery descent, its outer layers vaporize and peel away in a process known as ablation. The smaller the meteor, the more likely it is to burn up completely before reaching

On August 21, 1986, a sudden, catastrophic natural phenomenon occurred at Lake Nyos, a deep volcanic crater lake in northwestern Cameroon. Deep beneath the surface, years of volcanic activity had heavily saturated the water with a massive, highly pressurized concentration of carbon dioxide gas. A sudden underwater landslide triggered a limnic eruption, causing the lake to violently flip and release a massive gas bubble into the night air. The explosion shot a dense, heavy cloud of roughly one hu

Video taken in Rome, New York captured a three-foot meteor falling to Earth over Massachusetts on Saturday afternoon. According to NASA, the meteor appeared to fragment at an altitude of 40 miles. The energy released at breakup is “estimatee to be about 300 tons of TNT.” #meteor #massachusetts #sound #video #fyp
