  Which of the statements below does not explain the movements of the earth’s crust?  Many years of stress on the rock may fracture the crust causing one portion to slide upward ordownward with respect to the other. The mantle beneath the earth’s crust is made of plastic materials that have convection currents.Earthquakes that srcinate beneath the sea can produce tsunamis. The earth’s crust has cracked into huge plates which move slowly due t convection currents in the mantle.Question 2Salt water has a density greater than that of pure water.
