Q: Answer the following question given this paragraph: The theory of plate tectonics explains most of the features of Earth's surface. Plate tectonics helps us to understand where and why mountains form. Using the theory, we know where new ocean floor will be created and where it will be destroyed. We know why earthquakes and volcanic eruptions happen where they do. We even can search for mineral resources using information about past plate motions. Plate tectonics is the key that unlocks many of the mysteries of our amazing planet. Q: What theory explains most of the features of earth's surface? Choices: - Big Bang theory - flat earth theory - string theory - plate tectonics A:
A: plate tectonics
