what evidence did alfred wegener use to support the idea of continental drift?
a. similarity of rocks on the two sides of the atlantic ocean
b. similar fossils found in north and south america
c. land bridges present between several continents
d. ocean currents moving in predictable paths around eai

Explanation:

Alfred Wegener used the similarity of rocks on the two sides of the Atlantic Ocean as evidence for continental drift. Similar rock - types and geological structures on separated continents suggest they were once joined. Fossils found in similar locations across different continents also supported his theory, but the option mentions only North and South America which is less comprehensive compared to the rock - similarity evidence across the Atlantic. There are no land bridges between continents as proposed by Wegener's time, and ocean currents are not related to continental drift evidence.

Answer:

A. Similarity of rocks on the two sides of the Atlantic Ocean
