The name for such a hole is "caldera" which is a word of Spanish origin meaning "a pot" or a "cooking pot" (thing of cauldron!) - and this word is used because it resembles the shape of this hole.
Often the Calderas are filled with water forming lakes and often there is an island in the middle of the water.
Fulcrum I believe
hope it helps
It is formed through pyroclastic rock fragments as it builds up it makes a cinder cone. I hope that helps...
C sounds the best answer to find the exact location
The correct answers are:
- Formation 2 is an intrusion;
- Formation 1 in an extrusion;
- Formations 1 and 2 are igneous rocks;
The formation one on this image is an extrusion, and the reason why it is an extrusion is that it has come out on the surface. The formation two on this image is an intrusion, and the reason why it is an intrusion is that it has formed deep into the ground.
Both of the formations will produce igneous rocks. The formation one will produce extrusive igneous rocks that will have very small crystals because of the quick cooling off of the magma. The formation two will produce intrusive igneous rocks that will have larger crystals because of the slower cooling off of the magma.
