#1 what evidence did alfred wegner use to supports his theory of continental drift?
#2 why do you think people didint believe the continetal drift theory when wegner first explained it
#3 Who were the two scientists that brought forth supporting evidence to Wegner's theory, and what was their evidence?
#4 What are the three different types of plate boundaries, describe each type?
two tectonic plates collide
Two tectonic plates separate and new crust is forming from magma that rises to the Earth's surface between the two plates.
transform plate boundaries
"Transform boundaries occur when two plates are sliding along each other in opposing directions. Due to friction when the plates buckle and shift, they often cause earthquakes."
#5 What types of movement can occur between plates and what features can form from this movement?
convergent=mountains or volcanoes
#6 Give a specific example of a location on Earth where each type of plate boundry is present.
#7 what do plate tectonics and ocean trenches have in common?
"Plate tectonic and ocean trenches have in common the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate called subduction."
