Final answer:
Plate tectonics is supported by seafloor spreading, earthquakes, and continental drift.
Step-by-step explanation:
Plate tectonics is the scientific theory that explains how Earth's lithosphere is divided into several large, moving plates. Several pieces of evidence support the theory of plate tectonics, including seafloor spreading, earthquakes, and continental drift. Seafloor spreading occurs at mid-ocean ridges, where new crust is formed and pushes the existing crust apart. Earthquakes usually occur along plate boundaries, where plates interact and create stress, leading to the release of energy. Continental drift explains how the continents have moved and separated over millions of years.
