Which evidence was used by Wegener to support his hypothesis that the continents had once been joined?

Question

a: Rock types and ages
b: plate techtonics
c: slab pull and ridge push
d: fossils of ocean plants

Answer 1

Pretty much all of those... The fact that all of the continents can fit together like a puzzle and that plant and rock types of continent coasts are found on other continent coasts.

Also the fact that the continents are still moving "away" from one another.

Answer 2

Wegener noted 4 things:
-The Geometric Fit of the Continents
- The Geologic matches of rocks found on both South America and Africa
-Fossil matches on both S America and Africa
-And PaleoClimatic evidence as well...

Answer 3

Rock types and ages. Wegener noted that there were similar rock types of similar ages in both South America on the east coast and Africa on the east coast. Later on it was discovered that there were similar fossils as well adding to Wegener's hypothesis and move to the theory of plate tectonics..


Wegener never proposed plate tectonics fully. He didn't use that term. He proposed continental drift. Plate tectonics didn't become a fully accepted theory until the 1960s.

Answer 4

The Rocks Match
Broad belts of rocks in Africa and South America are the same type. These broad belts then match when the end of the continents are joined

We just got finished learning this again in my earth science class.

Answer 5

The contour matches to its nearby country in several places.

Answer 6

a

Answer 7

wasnt it tropical trees in Antarctica??
