Question

4. Before the present theory of plate tectonics, scientists used the hypothesis of continental drift to propose that Earth's continents are in motion. Which of the following were initially used to support the hypothesis of continental drift?
I. the matching shapes of continent edges
II. similar fossils on different continents
III. matching rock types on different continents
IV. evidence in the rock record for climate change
II and III only
II, III, and IV only
I, II, III, and IV
I and IV only

Answer 1

I, II, III, and IV

I'm not too sure about IV, but I'm sure about I,II, and III, so this must be the answer.

Answer 2

Answer:

I, II, III, and IV

Explanation:

    It was in 1912 that the first geologist elaborated a formal theory that the continents, at some point in geological history, would have been only one. He noted that some fossils, soil types, and vegetation were the same or similar in different regions of the earth separated by oceans.

   However, it was only after World War II (1939-1945) that the movement of the Tectonic Plates was scientifically discovered, the missing piece for proof that the continents were moving and had previously split. Over the years, scientists have been discovering and describing the stages of formation of the present form of the earth.
