Without volcanoes, most of Earth’s water would still be trapped in the crust and mantle. Early volcanic eruptions led to the Earth’s second atmosphere, which led to Earth’s modern atmosphere. Besides water and air, volcanoes are responsible for land, another necessity for many life forms. Can volcanoes be dangerous evenRead More →
Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes, volcanic activity, and crustal deformation. Why are earthquakes deep at convergent boundaries? The deepest earthquakes occur within the core of subducting slabs – oceanic plates thatRead More →
In 2015, National Geographic scientists including explorer Brennan Phillips discovered a phenomenon that they never predicted: two species of sharks living inside the crater of an underwater active volcano. … (Humans, you see, cannot physically survive traveling inside an active volcano themselves.) Why do sharks live in volcanoes? There areRead More →
Volcanoes usually form at the boundary between the Earth’s tectonic plates, which is why in America, they’re mostly concentrated in the West, Hawaii, and Alaska. In which location would you most likely find volcanoes quizlet? In which location would you most likely find volcanoes? along mid-ocean ridges and where aRead More →
Cinder Cone Volcano: A cinder cone volcano has low silica levels and high levels of dissolved gas, resulting in fluid lava that erupts explosively as a result of the immense pressure built in the magma chamber. Are cinder cone volcano eruptions dangerous? The primary danger from cinder cone volcanoes isRead More →
Generally speaking, you could say that an active volcano is one that is currently erupting, or has erupted in the last 10,000 years. … An extinct volcano is “dead” — it hasn’t erupted in the past 10,000 years and is not expected to ever erupt again. When was the lastRead More →
