What is Geology?
Geology is the study of Earth and its processes.
-Example: rock cycle
1.24.12
What is the continental drift theory, who came up with the theory, and what evidence did he use to support his theory?
Continental Drift is the hypothesis that continents had once formed a single land mass and then moved away from each other created by Alfred Wegener. He used fossils to support his theory, along with the fact that the continents fit well together.
1.26.12
Using your computer, describe who Harry Hess is.
Geologist who discovered sea floor spreading and helped the plate-tectonics theory. Also served in war.
1.27.12
What do scientists use to map the ocean floor?
They use sonars to see the bottom of the ocean.
2.1.12
What is the most interesting concept you have learned about this subject?
That there are many types of fault lines.
2.2.12
Explain crust recycling.
Magma comes up and moves, hardening on the ocean floor. The hardening magma then sinks down into trenches, where it will melt and come up again.
2.13.12
What do you know about transform, convergent, and divergent boundaries? Discuss land forms and movement.
Transform boundaries: Shearing, friction, side by side. San Andreas Fault Line. Fault Lines occur.
Convergent: Continent<-->Continent (folded mountains), Continent<-->Oceanic (SUBDUCTION, volcanic mountains, trenches), Oceanic<-->Oceanic (Island Arc, Ocean Volcanoes).
Divergent: Plates pull apart, Mid-ocean ridge, Magma comes up from the mantle, rift valley.
2.14.12
What evidence supports plate tectonics?
Fossils, seafloor spreading, reverse polarity, climate change, and how the continents fit well together.
