Alfred Wegner noticed that Greenland had moved a mile away from Europe in a
hundred years and that Paris and Washington, D.C., seemed to be moving apart by
about 15 feet each year while San Diego and Shanghai got about 6 feet closer Alfred
Wegner
I think people didn’t believe Alfred Wegner because the idea probably sounded crazy
and because he didn’t have enough evidence for people to believe it.
Arthur Holmes and Harry Hess brought forth supporting evidence, Arthur said that
thermal convection in the earth's mantle could cause continents to move and that the
continents didn't move but were "carried" by larger pieces of the earth's crust. Harry
worked and led to the development of plate tectonics. More information Harry Hess
The four types of divergent boundaries are Divergent boundaries, where new crust
is generated as the plates pull away from each other. Convergent boundaries are
where crust is destroyed as one plate dives under another. Transform boundaries are
where crust is neither produced nor destroyed as the plates slide horizontally past
each other. Plate boundary zones as in broad belts in which boundaries are not well
defined and the effects of plate interaction are unclear. Divergent boundaries
A place on Earth where each type of plate boundary is present, is The Mid-Atlantic
Ridge, it is a mountain range extends from the Arctic Ocean to beyond the southern
tip of Africa. It is the best known of divergent boundaries. The mid Atlantic ridge
The three different types of convergent plate boundaries are first, the Oceaniccontinental convergence, the Oceanic-oceanic convergence, and the Continentalcontinental convergence. Convergent boundaries
The Mediterranean-Alpine region between the Eurasian and African Plates.
They both involve the ground moving apart, or sliding across. Except for one happens
in the ocean and the other happens on dry land. More information
The age of the rocks increases as one move away from the rift zone. The midoceanic
ridge is the primary site for sea-floor spreading. Sea-floor spreading

12. Faults cause the uplift of blocks of crustal rocks, also stresses can be made in the
crust by tectonic forces that cause continental crustal areas to collide faults
13. Tensional stress is what causes normal faults, which is why they often occur. The
down-dropped blocks make the grabens and the uplifted blocks make horsts. They can
be found where tensional stress has recently affected the crust, the grabens make rift
valleys and the uplifted horst blocks make linear mountain ranges grabens and horsts
14. The mountains in the western U.S. were made by faulting processes and are called
Fault Block Mountains. More information
15. Two Bad things that can happen are Earthquakes and Volcanic eruptions. These are
natural disasters and can will destroy people’s homes if not kill them. Volcanic
eruption, earthquake
16. Two good things that can come from Plate tectonics are fertile soils and fossil fuels.
Without these things we wouldn’t have a lot of the things we today. More
