Fill in the Blank 26) [Rift valleys are formed when Continental plates diverge. Example: Iceland 27) Monitoring [Seismic waves given off by earthquakes allowed geologists to determine what each layer of the earth is made of and to map where the plate boundaries are located. 28) The main type of rock found in Oceanic Crust is [Basalt 29) The most abundant type of rock found in Contintnetal crust is [Granite 30) [Sonar technology was developed to locate submarines during WW2, it was also used to accurately map the sea floor. 31) [Pangaea is the Greek word for "all the earth." 32) When 2 Continental plates collide at convergent boundaries [Mountains are formed. Example: Himalayas 33) [Deep-OceanTrenches are formed along subduction zones between converging Continental and Oceanic plates or 2 converging Oceanic plates. 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.
