Question

Which evidence convinced many geologists that the continents were slowly moving?

A. the fit of the continents together

B. seafloors older than the continents

C. alternating symmetrical patterns of paleomagnetism on the seafloor

D. older rocks found at mid-ocean ridge compared to the seafloor margins

Answer 1

The evidence that convinced many geologists that continents were slowly moving is Option A: the fit of the continents together.

Step-by-step explanation:

In 1912, Alfred Wegener produced evidence that continents were moving but his idea was rejected by geologists. After about 50 years, Harry Hess confimed that Wegener's ideas were correct. He explained how the sea floor was spreading to prove that continents were in motion. It was also called the idea of continental drift.

The bottom of the sea was not smooth, there were volcanic eruptions and canyons. Harry explained that Earth's crust has been moving away on each side of the ridge of the ocean. So, the fit of the continents together proved that continents were moving.
