A caldera
crater
Crater
It is a volcanic caldera which is a large, bowl-shaped volcanic depression that forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption.
It's Hawaii.
When a volcanic cone collapses it forms a caldera.
No. Table Mountain is a mesa. It formed as a result of an erosion-resistant layer of sandstone at its top protecting the layers below.
A volcanic mountain is a mountain formed by volcanic action. It is usually cone-shaped with a depression on top, which is where the crater is, or was, in the case of extinct volcanoes. Volcanic mountains rise up as a result of movement of the tectonic plates beneath the earth's crust, which allow the magma to rise up from the mantle underneath.Ancient volcanic mountains may have misshapen and craggy-looking upper portions. These are the volcanic plugs left behind after centuries of erosion have worn away the soil from around the plug.a volcanic mountain is a mountain that is able to erupt.
what happens is that it forms a caldera
is decreases
It pops
Most volcanoes, when they finish erupting, leave a crater behind when the magma retreats down the volcanic pipe. Occasionally this will fill with water to leave a lake.A large surface explosion will leave behind a Caldera - a broad area possibly still of geothermal activity. Such as Yellowstone, or Okataina.
