Name the two supercontinents that formed after pangea split during the triassic and jurassic.

Since no one's posted a question in a while,

1. Alfred Wegener used which of the following pieces of evidence to prove his theory of continental drift? (Select all that apply)

a) Matching coastlines of continents now separated by oceans.
b) Evidence of glaciers in areas that are now tropical.
c) The composition of meteors from outer space.
d) The diversity of species of fossils, especially those of dinosaurs and
mammals.
e) The pattern of similar mountain belts on different continents.

2. However, what crucial part of the theory was Wegener unable to prove?

I don't see how the diversity of species could be evidence for plate movement; if you had said that the same species of fossils are found on completely different continents, that would have made sense.

What is the geologic feature formed by a depressed area in between two normal faults?

...a graben
and I see what you mean on the wording for that answer choice. I guess it could have been like what you said so it'd be less confusing.
