How do volcanic eruptions affect the atmosphere?
Regional SpecificsVolcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere — most of it is removed within several days to weeks — and has little impact on climate change. How do volcanic eruptions affect the
Do most earthquakes occur along existing faults?
Regional SpecificsEarthquakes Can Happen Along Intraplate Faults Earthquakes can occur along faults far from the edges of plates. Although these earthquakes are much less common, they are due to the same forces that cause earthquakes along plate boundaries. Do all earthquakes occur on faults? Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal

How many cm does the glacier move in 1 day?
Natural EnvironmentsGlacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d). How fast does a glacier move per hour?
