1. What pieces of evidence did Wegener use to reconstruct Pangaea and support his theory of continental drift?
His book "The Origin of Continent and Oceans"
2. How did the concepts of magnetic reversals and seafloor spreading help to bring about the theory of plate tectonics?
Magnectic Reversals was discovering by dating and determining the orientation of the remanent magnetism in lava flows on the land
Seafloor spreading to account for continents movements.
3. Why do geologists call plate tectonics a "unifying theory?""the envidence for it is overwhelming and because it ties together many seemingly unrelated geologic feature and event and show how they are interrelate"
4. Describe the plate movements along each of the three different types of plate boundaries.
Divergent Boundaries or spreading ridges, occur where plates are separting and new oceanic lithosphere is forming.
Transform Boundaries occur along fractures in the seafloor known as transform faults where plates slide laterally past one another roughly parallel to the direction of plate movement.
Covergent Boundaries occur when two plates collide and the leading edge of one plates and eventally incorporated into the asthenosphere.
5. How does convection within Earth's mantle drive plate tectonics?
Are my answer right?
