Question

What concept did Alfred Wegener propose in the early 1900s after studying rock formations, fossils, and the climate of Earth? The age of the Earth was millions of years older than scientists at the time had thought. All of Earth's continents, at one point, were a single massive continent that eventually split apart. Animals were slowly evolving to survive in their various climates and conditions. The Sun was the center of the universe, not the Earth. Flag Question

Answer 1

All of Earth's continents, at one point, were a single massive continent that eventually split apart.

In 1912, Wegener proposed his hypothesis of continental drift, which stated that Earth was once a single, large supercontinent that eventually broke apart. He called this single large continent Pangaea.

Answer 2

The correct answer is B.
Alfred Wegener was a German geophysicist and meteorologist. One of his greatest works is the theory of continental drift, which was focused on the idea that Earth's continents are slowly drifting around the Earth. He proposed that the continents were compressed into one protocontinent (called Pangaea) and that over time they drifted apart into their current position. Although his theory was not widely accepted in the beginning, continental drift is the basis for today's model of plate tectonics.
