Compare volcanic crater to a caldera?
A Crater is a bowl shaped depression in the Earth's surface. It could be made by an impacting meteor, an underground land collapse, or perhaps may be found at the top of a volcano [= collapse].A Caldera is of volcanic origin, (but without a noticeable volcanic cone), where there was an eruption after which the magma chamber collapsed and is now filled in. Yellowstone is one notable example, and the Taupo Lake another.

What forms at the top of a volcanoe mountain when it collapses?
Most volcanoes, when they finish erupting, leave a crater behind when the magma retreats down the volcanic pipe.
