The Pangaea Theory The Pangea theory describes that all continents were joined together in one enormous land mass millions of years ago. Later on the continents broke apart and start drifting in opposite directions and still continued to make another arrangement. In 1912‚ Alfred Wegner‚ a German meteorologist and geologist gave the hypothesis the all the continents were joined together in a single continental land mass surrounded by a single ocean (Panthalassa) Late Paleozoic times.

Explain the differences between Basaltic‚ Rhyolitic and Andesitic volcanic eruptions with reference to processes‚ which lead to the eruptions‚ the type of volcano produced and the reasons for the differences between the material erupted by these volcanoes. Volcanic eruptions are caused by a red-hot liquid rock‚ called magma inside the earth’s core. Volcanoes erupt when magma rises to the surface of the earth‚ which causes bubbles of gas to appear in it. This gas can cause pressure to build up in

theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries. Wegener’s theory of continental
