The volcanic craters that contain lakes are not extremely rare, however for a lake to form the volcano must have a low level of activity. If the temperature of the volcano gets too warm preceeding an eruption or shortly after an eruption the water will simply convert to steam and will not become a lake. However if the crater is cool enough and is enclosed, as long as there is a supply of water a crater lake will eventually form within the volcano.
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
Yes
There is a crater on the top of a moon and a volcano.
a crater can be formed anywhere in a volcano. its usually formed at the top though.
the bowl shaped opening of a volcanoe is a crater
Crater Lake (My favorite: it sits in the top of Mt Mazuma, a dormant volcano) Buckeye Lake Razz Lake Twin Lakes Willow Creek Lake
The name of the hollow landform, found at the top of the volcano is called crater.
a funnel shaped vent at the top of a volcano is a crater
at the top
The top of a volcano may be a peak, lava dome, vent, crater, or caldera (empty magma chamber), depending on the state of the volcano. The top of any mountain can be called its summit.
The highest point, or "peak" of a mountain.
Caldera
