Use Chapters 22 and 25.5 in Conceptual Integrated Science to address the following items in your notes:
1. Why did Wegener’s hypothesis of continental drift fail and what was the evidence needed to support his predictions- why was it literally an idea before its time?
Because no one could explain how massive continents of solid rock could drift across earths surface. It was ahead of its time because there was no way of finding the evidence to support it until technology was invented in the form of a fathometer to map the deepest depts. Of the ocean floor.
2. Summarize plate tectonics. It explains the theory of how the changing surfaces of the earth are formed.
3. What are convection currents and what is their role in plate tectonics? Convection currents are the rise and lowering of heat in te earths mantle like a boiling pot of water. The heat is denser at the bottom of the pan it rises the falls to the bottom and reapaets it self. This rising and dropping is the effect that why the plates move.
4. Compare the three types of plate boundaries: divergent, convergent, and transform plate boundaries. Explain the movement and processes associated with each boundary, the landforms that develop as a result of these processes, and the locations where these boundaries/landforms are found on Earth.
movement and processes associated
landforms that develop as a result
Divergent
Plates are moving away from each other Mountains, lava fills the area when the plates move away from wach other and cools causing
Convergent
Plates come together in slow motioncollisions. One plate falls below the other.
Ocean mountains, mountain ranges and coastal moutain
Transform
They just slide past wach other
Connect two ridges to make one continuous ridge
locations where on
Earth
