4. (Fossils), Humans,Bones), rocks, and climate provided Wegener with support for his continental drift theory.

5.The fact that the (youngest),oldest) rocks, are located at the mid-ocean ridges is evidence for seafloor spreading.


6.The transfer of (solar),heat) energy inside Earth moves plates.

Alfred Wegener was one of the first people to suggest that all of the(Continents)were joined together in the past. He called the one large continent(Arctic).Evidence exists to support his hypothesis. For example, similar fossils have been found in South America and(Africa).Also,fossils of warm weather plants have been found in the(seafloor spreading)Similar(rock)structures exist in the Appalachian mountains and in Greenland and western Europe. But until clues on the ocean floor led to Harry Hess's theory of(Pangaea)scientists could not think of how the contains might move.







2nd paper

1.Earth's crust and upper mantle are broken into sections called
Plates

2.The collision of one continental plate with another may produce
Mountains

3.New ocean crust is formed at a
Mid-ocea-ridge

4.A rift valley can form where two continental plates .
Colliding

5.Where Earth's plates move, they at slide alongside one another, pull apart, or
Divide
