Which statement best explains the theory of plate tectonics
The theory of plate tectonics is the scientific understanding that Earth's outer shell is divided into several large, rigid pieces called tectonic plates. These plates are constantly moving and interacting with one another, which influences a variety of geological activities such as earthquakes, volcanic eruptions, and the formation of mountains. The best statement that explains the theory of plate tectonics is:
"Plate tectonics is the scientific theory that describes how the Earth's outer layer is made up of several moving, interacting plates, which cause various geological phenomena."
To understand this theory, scientists have collected various types of evidence from around the world. This evidence includes the study of earthquakes and volcanoes, the mapping of the seafloor using sonar, analyzing the Earth's magnetic field, and observing how continents fit together like puzzle pieces. By combining all these pieces of evidence, scientists have developed a comprehensive understanding of how the Earth's plates move and interact, leading to the theory of plate tectonics.
