A Caldera
A crater is not a separate material or part of a volcano. It is a depression or hollow at the summit of a volcano that forms when the volcano erupts and releases magma, gases, and other materials. The crater is a result of the collapse or expulsion of material during the eruption.
Doline or Shakehole - the names given to the resulting depression if the collapse extends to the surface.Within the cave a collapse is often simply called that - "collapse", the result being a pile of boulders that may fill the passage completely, forming a boulder choke. (also boulder ruckle in the UK at least - possibly cavers' regional dialect.)
how is the crater density used in the relative dating
The possibility exists that the Decca Traps flood basalts were the result of volcanic activity triggered by a massive impact just off the western coast of India, where a large impact crater called the Shiva Crater has been discovered. This crater's formation seems to coincide in time (68-60mya) with the formation of the Decca Traps.
YES!!! The adjective 'Lunar' from Latin, means of the Moon.

Financial collapse is the primary form of collapse due to corruption.
No. Mount Mazama, the volcano that holds Crater Lake, formed as a result of a subduction zone.

It's a crater on the surface of the Moon, probably the result of an asteroid impact.

A sinkhole is the term used to describe a depression in the ground caused by a cave collapse. It can also be the result of acidic water dissolving limestone.
The process is called desertification.
Amboy Crater in California is a cinder cone volcano. It is a relatively small and symmetrical volcano that was formed by explosive eruptions of mostly cinders and scoria. The crater is the result of a single eruptive event that occurred thousands of years ago.
