Why is there stress on the Earth's crust? How do tsunamis affect the cryosphere? Why is HF so corrosive? Why do volcanoes erupt in different ways? Why do volcanoes cause lightning? Why are silicate minerals typically not considered to be ores?
the pool of magma growing larger and larger. Magma, however, is lighter than the surrounding rock, and this buoyancy puts pressure on the top of the magma chamber. When there's enough magma in the chamber, the top of the chamber cracks open and the devastating flood of magma comes bu...
Forairlinesto resume flights, the ash needs to clear and there needs to be a low probability of further eruptions. Passenger safety is the priority The underpinning reason behind these flight cancellations is safety. If you lose engines and you can't see out the window, the risk to passenger...
