What did each of the following people contribute to plate tectonics and geology?
1. Abraham Ortelius
2. Marie Tharp
3. Charles Lyell
4. Abraham Gottlob Werner
5. Anton Moro

Part of the answer (Click to Show Hidden Text)

1. First person to theorize the continents were joined together 2. Used data to create a map of the Atlantic which led to the discovery of the Mid-Atlantic Ridge 3. Popularized work of James Hutton, especially involving uniformitarianism

Correct so far... I'm still looking for #4 and #5

Werner was a proponent of Neptunism (that rocks formed from crystallisation of ocean rocks) while Moro proposed the opposing view of plutonium, that igneous rocks arose from magma. I think this showed up at MIT or some other invitational and we weren’t able to find it on our cheat sheet. Oh well.

New question: which boundary produces earthquakes of the greatest magnitude and why?

[JoeyC]

I believe the correct answer to your question would be transform boundaries because of their tendency to have slip-strike actions which cause one plate to accelerate (relatively fast) til it collides yet again with the opposite plate. (whereas in convergence, resistance is always felt)

If I got it right, I guess the next question should be : what is the most dangerous type of landslide?

It’s actually convergent, generally at subduction zones: http://www.geo.cornell.edu/geology/facu ... -001-2.png

The reasoning is that there’s a much larger surface area for locking and frictional slip to occur.

I’ll let someone else answer your question.

[JoeyC]

Ah, that would make sense; they do have more area for friction than transform boundaries.

Rock fall?

[JoeyC]

Not quite, but nice try . This type of question is an obscene, yet important one, as it could be placed on a test as a tiebreaker, or worth extra points.

All right, no one's answered in a while, so I'll give it another try (Click to Show Hidden Text)

Rock topple?

Correct!
A rock topple, or more (more simply) a topple, is the most deadly form of landslide, due to the fact that it is literally part of the rock face peeling off the rock body and toppling over (think onion layers, except these layers are made of huge rock, and the ant quivering right where it's going to land is you).
I'll give someone else a chance to ask a question

To clarify, does that mean it's my turn to ask a question or no?
