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).
â¢ Erectus was taller and more robust than many Homo species while habilis was a small species, measuring about little over four feet. â¢ Erectus is closer in evolutionary relationship with human compared to habilis.his is an interesting and important hominid species, which is believed to have formed the bridge between erectus and Australopithecines. However, they also lived with both these species together in different times. It has been a common agreement that these hominids were the first to evolve of the Genus: Homo.
