Question

1. what other evidence did wegener need to make scientists believe his idea?

rare rock samples that could be found on two different continents
shores from different continents that matched each other like a puzzle
a strong enough force that could move the continents
the same fossil evidence on two different continents

Explanation:

Wegener ya presentaba evidencia como similitudes de costas, rocas y fósiles entre continentes para su teoría de la deriva continental. Lo que le faltaba era demostrar la fuerza física capaz de desplazar los continentes, lo que los científicos de su época pedían para aceptar su idea.

Answer:

C. a strong enough force that could move the continents
