Wegener was a climatologist and geophysicist who, in 1915, suggested that continental drift and plate tectonics. He suggested that a supercontinent he called Pangaea had existed in the past, broke up starting 200 million years ago, and that the pieces 'drifted' to their present positions. His arguments in support of continental drift included:

o the fit of the continents
o paleoclimatic studies that showed evidence of past glaciation, coal deposits, ancient reef deposits, ancient sand dunes, and salt beds that make no sense in today's world climate belts
o the occurrence of the same fossils on lands now ...

    Volcanic eruptions with preheated eruptions, explosive eruptions, and effusive eruptions have the potential of having a severe impact. The lava flows and emission of carbon dioxide can pose a hazard to human beings.

  • Continental Drift

    Volcanic activity, such as in the Ring of Fire, is produced by a different component of plate tectonics. The Pacific Ring of Fire has a large amount of earthquakes and volcanic eruptions that occur in the basin of the Pacific ocean.

  • EFFUSIVE VOLCANISM ON MARS

    On Earth, the tectonic flow of the crust across the hot volcanic regions prevent large volcanoes from forming. The Hawaiian islands were created as the Pacific plate moved northwest. These volcanoes have a relatively short life time.
