Climate zones are very either cold, and often near poles (North and South) or very warm (tropics, equator.)]]> 2020-01-30 14:33:33 UTC https://padlet.com/nathanm5_1/b8f2gf2bbob5/wish/438169371 nathanm5_1 https://padlet.com/nathanm5_1/b8f2gf2bbob5/wish/438169960 2020-01-30 14:34:20 UTC https://padlet.com/nathanm5_1/b8f2gf2bbob5/wish/438169960 nathanm5_1 https://padlet.com/nathanm5_1/b8f2gf2bbob5/wish/438171600

• Alfred Wegener: The man who came up with the continental drift hypothesis
• Pangea: a supercontinent that contained all of today's continents, but they spread out
• Continental drift is Wegener's theory the gradual movement of the continents across the earth's surface through geological time

Seafloor spreading is almost an expansion on continental drift, which give a better understanding of volcanoes and Earthquakes.  The seafloor spreads and opens up land for Earthquakes, and collides to form mountains, volcanoes and ridges.  This was Harry Hammond Hess's theory that shifting moved by the sea.

Where two plates come together is a plate boundary.  The 3 types of boundaries are Convergent (together) Divergent (away) and they can slide past each other.
