which of these pieces of evidence did Alfred Wegner cite to support his hypothesis of continental drift?
1. New oceanic crust formed between the northern and southern continents, pushing them apart
2. Similar fossils have been found at the bottom of the ocean and on land
3. Contraction of the earth caused folded mountains to form
4. the continents fit together like a puzzle
Plzz help
1) Which of these pieces of evidence did Alfred Wegener cite to support his hypothesis of continental drift?
The continents fit together like a puzzle.
2) At which type of boundary is new oceanic crust created?
A divergent plate boundary.
3) Which best explains mantle convection?
Cooler material in the mantle moves down, and warmer material in the mantle moves up
Your welcome.
A devergent plate boundary
Cooler material in the mantle moves down, and warmer material in the mantle moves up
The continents fit togehter like a puzzle
I just submitted it and the answer is 4
It’s the continents fit together like puzzle pieces 🧩
Together* sorry <33
???? is correct!
yes, ???? is correct
ごめんなさい is correct

Yay 100% correct.
Alfred Wegener cited the following pieces of evidence to support his hypothesis of continental drift:
1. New oceanic crust formed between the northern and southern continents, pushing them apart: Wegener observed that the continents appeared to fit together like a jigsaw puzzle. He proposed that the continents were once joined together in a supercontinent he called Pangaea, which later split and drifted to their current positions. Horizontal movements of the Earth's crust, driven by the creation of new oceanic crust at mid-ocean ridges, were suggested as the mechanism for the movement of continents.
2. Similar fossils have been found at the bottom of the ocean and on land: Wegener noted that fossils of the same species were found on multiple continents across ocean basins. For example, he observed that the remains of the ancient reptile Mesosaurus were found in both South America and Africa. He argued that this distribution made more sense if the continents were connected at some point rather than if the organisms had crossed vast oceans.
3. Contraction of the Earth caused folded mountains to form: Wegener argued that some mountain ranges, such as the Appalachian Mountains in North America and the Caledonides in Europe, exhibited similar geological features across continents that today are separated by large ocean basins. He suggested that these mountains formed when the continents collided during the process of continental drift.
4. The continents fit together like a puzzle: As mentioned earlier, Wegener observed that the coastlines of continents seemed to match like pieces of a puzzle when they were brought together. This provided an initial visual clue that the continents may have once been connected.
In summary, Wegener's evidence for continental drift included the fitting of continents, the presence of similar fossils across continents, the occurrence of folded mountains on different continents, and the formation of new oceanic crust pushing the continents apart.
