b. they mapped the structures on the ocean floor using sonar rays to collect data
Marie Tharp and Bruce Heezen contributed to the development of the theory of plate tectonics through their extensive work on mapping the ocean floor. They used sonar to collect data, which enabled them to create detailed maps of the ocean floor's topography. Their work revealed the presence of the Mid-Atlantic Ridge and helped suggest that the seafloor was spreading, which was a crucial piece of evidence in support of the theory of plate tectonics.
which of the following describes how Marie Tharp and Bruce Heezen found evidence that led to the theory of plate tectonics?
a. they observed that the continents seem to fit together like a puzzle
b. they mapped the structures on the ocean floor using sonar rays to collect data
c. they mapped the structures on the ocean floor using a video recording to collect data
d. they observed two tectonic plates moving away from each other
