Missouri, Indiana and other states in the central United States have experienced significant earthquakes, yet none of these states are located near the edge of the North American tectonic plate. What causes earthquakes in areas between tectonic plates?

A) Earthquakes occur because there are no volcanoes to relieve the pressure from heat in Earth's core.

B) There are faults deep under the surface of the earth in these areas caused by motion of the tectonic plates.

C) These earthquakes are all the result of human activities such as oil and gas production, not natural seismic activity.

D) The crust is thinner in the center of a tectonic plate because magma in the lithosphere flows to the edges of tectonic plates.
