Identify the categories of proof used by Wegener as evidence of drifting continents. Select the two correct answers.

1. evidence from the seafloor

2. evidence of glacial deposits

3. evidence of the speed of plate movement

4. evidence from fossils

2. evidence of glacial deposits

4. evidence from fossils

Explanation:

Alfred Wegener was the first to give evidence about the continental drifting. He saw that the south american continents and the Atlantic coastline of Africa had great similarities. He believe the continents are once together but due to continental drifting they separated forming different continents. He notice the edges of these continents fit like a puzzle when joined together.

Alfred Wegener also gave evidence of similar fossils remains found in different continents like the glossopteris plant which was found in five continents. He believed the similar fossil remains can be best explained if the continents were once together.

Alfred wegener also used glacier deposits to show evidence of continental drifting. He used glacier deposits to ascertain cold climate near the south and north pole. He found out the ancient climate was same with the modern climates. sedimentary records was also used to finally determine the position of the north and south poles. He discovered their was a change in the north and south pole.

2. evidence of glacial deposits

4. evidence from fossils

Explanation:

1. that was found later by someone else which proved the theory more

3. it wasn't yet proven that continents drifted, so that couldn't be the case
