Who proposed and different kinds of evidenceAlfred Wegener Evidence – fossils, glaciers, mountains, the continents fit together
Types of convergent plate boundariesOcean-ocean Ocean-continent Continent-continent Features in common mountains and earthquakes
Types of divergent plate boundaryOcean-ocean Continent-continent Features in common There’s going to be a rift
Hot spot A volcanic activity That is made of hot solid material whichrises from deep in Earths mantle.
PLATES Plates move 2 to 5 cm per year.About the same speed your fingernails grow In a million year it would move 25 km
Major names of plates There are 7 major plates- Pacific plateIndo-Australian plate The north American plate Eurasian plate African plate South American plate Antarctic plate
