Fill in the Blank
26) [Rift valleys are formed when Continental plates diverge. Example: Iceland

each layer of the earth is made of and to map where the plate boundaries are located.

Short Answer
34) What is the main reason Wegener's Theory was not accepted by his fellow scientists?
He couldn't explain how continents could move
35) Explain how this map supports Continental Drift Theory.
It shows how the continents fit together like puzzle pieces. It shows how fossils of the
same plants and dinosaurs could be found on different continents.
36) What process is being illustrated in this image ? Explain.
Sea-Floor Spreading - magma rises in the mid-ocean ridge creating new sea floor. Old
sea floor is recycles by subduction at the deep ocean trenches.
37) Explain in detail what is happening between the South American Plate and African Plate. Why
is it Happening? What tectonic feature is created there?
They are diverging which is creating a Mid-Ocean Ridge. Magma is rising into the ridge
forming new sea floor and causing the sea floor to spread. This is causing the continents
to move away from each other. Convection Currents in the mantle are driving this
process.
