Sometimes after an eruption , the top of a volcano may collapse down into the partially emptied magma chamber. Which creates a very large opening called a caldera.
There are a few ancient Calderas in Texas. Texas isn't near any 'hotspots' or tectonic plate boundaries, so it's not volcanically active. The Calderas are in the western part of the state and are about 40 million years old or so... One in particular is the Buckhorn Caldera near Ft. Davis, Texas.
That term is 'calderas'
explanation = noun explanatory = adjective
Yes, volcanoes can form craters, which are depressions around the vent where the volcano erupts. Calderas are larger, basin-shaped volcanic depressions that can form after a volcano expels a large volume of magma and collapses. Lava plateaus can form when lava flows out of long cracks in the ground and spreads over a large area, creating a flat plateau-like surface.
No. Calderas form when a volcano produces an extremely massive eruption and collapses in on itself. But the volcano will often continue to erupt after this. For example, the volcano Krakatoa formed a caldera in 1883, but eruptions since then have formed a new island that is currently very active. There is evidence that the volcano has done such a thing several times.
Nigeria has no calderas.
Calderas can be occupied by lakes, but they do not have to be. Seomve calderas are dry while others are located beneath the sea.
Nobody dislikes aleandria calderas.

Calderas are typically larger than most impact craters, which are formed by meteorite impacts. Calderas are massive volcanic depressions that form when the ground collapses after a volcanic eruption depletes the magma chamber. The size of both structures can vary greatly, but calderas tend to be larger in scale.

Explanation (ex·pla·na·tion) is the noun form for the verb 'to explain'.
