Question

Which sources of evidence did Wegener use to support his theory of continental drift? Check all that apply.

Answer 1

Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents...

Answer 2

Wegener used fossils, the symmetrical fit of continents, and the distribution of rocks as evidence to support the continental drift theory.

• According to the continental drift theory in the past, all the landmasses were a single huge landmass called a supercontinent.
• Over the millions of years, the tectonic plates drifted away from each other due to plate movements to form 7 continents.
• Fossils: The fossils excavated from different areas are similar to those from neighboring countries.

• The symmetrical fit of continents: The continents when joined together to form a single landmass fit each other perfectly like a jig-saw puzzle.

• The distribution of rocks: The rock belts present across the continents have a striking symmetrical distribution.
