Question

A. New evidence was discovered that made scientists revise their ideas.
C. Tectonic plates have begun to move faster and faster over time.
B. There are more people studying science now than in the past.
D. Scientists can now travel underneath the plates and observe their motion.​

Answer 1

The validation of seafloor spreading in the 1950s and 60s

Step-by-step explanation:

The theory of seafloor spreading was supported by numerous evidence including thermal probes that showed that heat flow over the mid-ocean ridges measured up to four times those measured in general bottom sediments, which are taken as due to the presence of molten Earth material close to the ridge crest

The ridge crest also show signs unusually seismic wave velocities that are considered to be due to microfracturing and thermal expansion from upwelling magma
