A supervolcano is a volcano capable of producing a volcanic eruption with an ejecta mass greater than 1015 kg (1012 t). Supervolcanoes occur when magma in the mantle rises into the crust but is unable to break through it and pressure builds in a large and growing magma pool until the crust is unable to contain the pressure. This can occur at hotspots (for example, Yellowstone Caldera) or at subduction zones (for example, Toba).
Homo habilis. An extinct hominid of the genus Homo that lived between 2.3 and 1.4 million years ago in Africa in the early Pleistocene period. H habilis was short, but had a less protruding face and a higher, rounder and larger brain cavity (Â±650 cc) than Australopithecus (Â±450 cc).
Homo Habilis and Homo Erectus are two interesting species of the human or hominid evolution, and both are two extinct species.However, it is always confusing for an average person to figure out whether it was Homo habils or Homo erectus that lived earlier.hose fossils date back to different times, and those suggest the habilis man lived between 1.4 and 2 million years from today. Their cranial capacity ranged from 360 to 600 cm 3, which is much smaller compared to the human and H. erectus.
