Which of the following describes how Marie tharp and Bruce heezen found evidence that led to the theory of plate tectonics

Answer 1

Marie Tharp and Bruce Heezen found evidence for plate tectonics through their work in oceanography and mapping the ocean floor. They used data from shipboard surveys and sonar technology to create detailed maps of the ocean floor, which revealed a prominent underwater mountain range called the Mid-Atlantic Ridge. Tharp noticed that the ridge was more extensive and had a distinct pattern of valleys running along its length. This discovery led them to propose that the Earth's crust is divided into large, rigid plates that are constantly moving and interacting. This idea eventually formed the basis for the theory of plate tectonics.
