Which of the following types of seismic waves are the fastest? Love waves. S-waves. P-waves. Rayleigh waves. Which of the following types of seismic waves are the fastest? Love waves. S-waves. P-waves. Rayleigh waves. Explanation: Body waves are the fastest seismic waves, with P-waves faster than S-waves. Surface waves—Love waves and Rayleigh waves—are slower than body waves. Which of the following seismic waves showed that Earth’s outer core is liquid? Love waves. S-waves. P-waves. Rayleigh waves. Which of the following seismic waves showed that Earth’s outer core is liquid? Love waves. S-waves. P-waves. Rayleigh waves. Explanation: S-waves are transverse waves—they cannot travel through liquids. What is the significance of the Mohorovicic discontinuity (also known as the Moho)? The Moho shows that the inner core is solid. The Moho is the crust–mantle boundary. The Moho is the core–mantle boundary. The Moho is the boundary between oceanic and continental crust. What is the significance of the Mohorovicic discontinuity (also known as the Moho)? The Moho shows that the inner core is solid. The Moho is the crust–mantle boundary. The Moho is the core–mantle boundary. The Moho is the boundary between oceanic and continental crust. Explanation: The Moho marks the location where wave speed increases abruptly due to an increase of density. The denser rock is at the top of the mantle and the base of the crust. How does erosion of a mountain affect the depth to which its root extends into the lithosphere? Erosion has no effect on the depth of its root. As erosion occurs, the mountains root is forced downward due to isostasy. The eroding mountain is buoyed upward, which also raises the base of the mountain’s root. Erosion forces the lateral shifting of the mountain’s root. How does erosion of a mountain affect the depth to which its root extends into the lithosphere? Erosion has no effect on the depth of its root. As erosion occurs, the mountains r
