Question

question 23 (multiple choice worth 3 points) (03.03 mc) wegener observed that that coastlines of continents in the southern hemisphere had similar grooves. which of the following supports coastlines far away from one another having similar grooves? animal extinction glacial movement rock formation human interaction

Explanation:

Glacial movement can create similar grooves on different continents. When glaciers move, they erode the land beneath them, leaving behind characteristic grooves. If continents were once connected (as in the theory of continental drift), the same glacial activity could have created similar grooves on what are now far - apart coastlines. Animal extinction, rock formation, and human interaction do not typically create such large - scale, similar groove patterns on distant coastlines.

Answer:

Glacial movement
