Department of earth and space science and engineering. The complete test consists of 10 multiple-choice questions, 5 short answers and 1 short essay. Total: 27 marks: multiple choices (please circle the right answer) Total 10 marks: geologists have learned about the appearance and composition of mantle rocks from several sources. 2 marks answer: the dense oceanic crust sinks beneath the more buoyant continental crust at this type of convergent plate boundary. The convergence between two oceanic plates depends on the relative density and the age of the two. Generally the ocean crust that is older and (as a result denser) slides beneath the one that is younger and less dense: what 4 properties of seismic waves aided in understanding earth"s interior? answer: 2 marks (0. 5 each: they move fastest in high-density rocks. 2. influence of liquid on the 2 diff. types of waves. 3. they can be reflected/bounce off internal boundaries.
