PLATE TECTONICS, a raisin due to the cooling process that occurred on…

- - - - Tectonic is a term derived from a Greek word tekton means
        “carpenter or builder”.
      - also called Lithospheric plates, are massive,
        irregular slabs solid rock that envelope the surface of Earth.
      - states that the Earth's outermost
      - These plates fit together like the pieces of a jigsaw puzzle and the
        movement ranges from less than 1 to more than 15 cm per year.
      - THE PLATE TECTONIC THEORY
        
        was developed from earlier hypotheses
        and data collected about the rocks of the ocean floor.
        
        One of the foundational works that gave rise to this theory is the
        
        Abraham Ortelius
        
        America was originally connected to Europe
        
        Continental Drift Theory
        
        Alfred Wegener
        
        The Origins of Continents and Oceans in 1915.
        
        presented pieces of evidence
        
        theory that the continental landmasses were
        “drifting” across the Earth
        
        THE BREAK OF PANGAEA
        
        Wegener was convinced that all of Earth’s continents were once
        part of an enormous, single landmass
        
        Continents fits like puzzle pieces, animal fossils on separates side of the ocean, Plant fossils in Antarctica, Similar rocks in diff. continents, Glacial deposits in desert area.
        
        existed about 240 million years ago. By about 200
        million years ago, this supercontinent began breaking up.
        
        about 1,100 million years ago, there was
        a supercontinent named Rodinia, which predated Pangaea.
        
        MAJOR TECTONIC PLATES
        
        Earth is generally composed of 58 crustal plates. Out of these plates,
        
        Secondary plates
        
        Arabian Plate, Caribbean Plate, Cocos Plate, Indian Plate, Juan de Duca Plate, Philippine Sea Plate, Scotia Plate, Nazca Plate
        
        Tertiary plates
