A volcanic crater is a bowl-shaped depression in the ground caused by volcanic activity, usually located above the volcano's vent. [11] During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava.
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. [1] It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions , molten magma and volcanic gases rise from an underground magma chamber , through a conduit, until they reach the crater's vent, from where the ...
A krater or crater (Ancient Greek: κρᾱτήρ, romanized: krātḗr, lit. 'mixing vessel', IPA: [kraː.tɛ̌ːr] ; Latin : crātēr , IPA: [ˈkraː.teːr] ) was a large two-handled type of vase in Ancient Greek pottery and metalwork, mostly used for the mixing of wine with water.
See also volcanic crater. A topographic map of Ngorongoro Crater in northern Tanzania, the world's largest inactive, intact, and unfilled volcanic caldera, which formed when an immense volcano erupted and collapsed on itself 2–3 million years ago. The floor of the caldera is 600 metres (2,000 ft) below its rim and covers more than 260 square ...
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given ...
Shield volcano in Tharsis region on Mars with marked borders, circles represent impact craters counted by crater counting method. Crater counting is a method for estimating the age of a planet's surface based upon the assumptions that when a piece of planetary surface is new, then it has no impact craters; impact craters accumulate after that at a rate that is assumed known.
Now, this approach might have begun to play out for the No. 2 in the rideshare industry, Lyft (NASDAQ: LYFT). Both Lyft and the industry leader, Uber, saw their stocks crater after launching ...
