Which of the following choices is not evidence supporting the theory of plate tectonics?a. fossil assemblages

c. the jigsaw puzzle-like fit of the continents
d. traces of glaciation found in Africa and South America

Answers

Hi!
let's go through the options:

a. fossil assemblages

Imagine you find similar fossils in Africa and South America - it would tell you that the same animals lived on the same continents, suggesting that the continents were close together!
b. ancient cave drawing found in France - this only tells you that people used to live in France at the time the painting was created, not whether the continents moved - so this is the correct option!

c. the jigsaw puzzle-like fit of the continents

This jigsaw tells us that the continents likely moved so it's supporting the theory of tectonic movement

d. traces of glaciation found in Africa and South America
This suggests that those continents were previously somewhere else - that is, they moved! so again, it suggests the theory of tectonic movement

b. acient cave drawing found in france
