21. Some scientists interpreted these as requiring plate tectonic processes, such as seafloor spreading. 22. But plate tectonics is still shaking, shaping and re-arranging Earth's surface. 23. Kasting argues that a large moon is not required to initiate plate tectonics . 24. When a mechanism was discovered through plate tectonics , it became mainstream. 25. Geography and mid ocean ridges, contributed greatly to the theory of plate tectonics . 26. Earth's internal heat powers most geological processes and drives plate tectonics . 27. The plate tectonic evolution of a peripheral foreland basin involves three general stages. 28. This migration route provided evidence and support for the theory of plate tectonics . 29. The big-bang theory and plate tectonics are addressed in middle school. 30. Some geologists dispute whether convergent plate tectonics produced the Sonoma orogeny.
