Q: Which theory states that the entire crust is broken and is continuously moving? a. Continental Drift b. Seafloor Spreading c. Plate Tectonics d. Titanic Theory  A: The correct answer is Plate Tectonics Plate tectonics is a comprehensive geological theory that explains the dynamic behavior of the Earth's lithosphere, the rigid outer layer that includes the crust and part of the upper mantle. It suggests that Earth's lithosphere is divided into several large and small plates that are constantly moving, leading to phenomena like earthquakes, volcanic activity, and the formation of mountain ranges. 

Q: If you will plot the earthquake epicenters, active volcanoes and major mountain ranges on the map of tectonic plates, do you think there will be areas where these geologic features are concentrated? A:
