Alfred Wegener

J. Tuzo Wilson
How do these 20 placs move?
the magma thats inside the earth, which causes heat to move the placs(chaleur)
list 3 proven reasons that contients move
- corresponding continent shapes bwteen south america and africa
- same fossils on different continents.
- similar mountains on two sides of the atlantique
how wide is the lithosphere (plaque)
100km

what are continental glaciers
thick accumilations of ice that cover large areas of land. they are found in regions like greenland and antarctica
what are alpine glaciers
glaicers formed in mountainy conditions with regions of high altitude, where the temperature is right for the formation.
