The movement of these plates is normally very slow, but when the plates "slip" and move quickly, this causes earthquakes. Earthquakes generally occur at ruptures in the Earth's surface where two plates meet, called _______.
A. faultB. ridgeC. hot spotD. trench
The theory of plate tectonics explains how Earth's continents move. According to this theory, which of the following statements is FALSE?
A. Earth's crust is composed of relatively thin, light plates that float atop the dense, viscous upper layer of the mantle.
B. Ocean basins can grow along divergent boundaries, where the ocean floor splits and spreads apart.
C. Continental plates have relatively stable shapes because they are heavier than oceanic plates and tend to sink below oceanic plates where the two types meet.
D. Many of Earth's mountains resulted from the collision of two continental plates along a convergent boundary.
Identify the type of wave: surface wave, S-wave, P-wave, tsunami
a. Arrives first at seismic stations:
b. Travels only on the crust and causes ground to move in two directions: .
c. Travels in the crust and the mantle, but cannot travel through the outer liquid core:
d. Travels through the crust, mantle, and core:
