9+ mon, 2+ week ago   (587+ words) In a volcano, friction can create its own bubbles. This rewrites our eruption models. For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises toward the surface. When pressure falls, gases…...

10+ mon, 2+ week ago   (389+ words) Scientists have uncovered a massive impact crater in southern China’s Guangdong province. To confirm an asteroid impact, researchers analyzed the quartz for planar deformation features. (Representational image) A team of scientists has uncovered evidence that a massive asteroid strike created…...
