228. (c) Differences in temperature under oceans and continents (Because the first para suggests that "differences in temperature under oceans and continents" are responsible for convection currents which move the continental plates)
229. (b) Black Sea (Because the last line tells that "Gulf of Mexico, the Black Sea, and perhaps the North Sea" are older seas so they will have more sediments
230. (a) illustrate the effects of convection in the mantle (Because the first para tells about the "convection in the mantle of the earth" and "this convection would carry the continental plates along as though they were on a conveyor")
231. (d) guarded skepticism (Because the author has described the traditional view in the first para and then raised some issues regarding this traditional view in the second para and in the third para he suggests another view)
232. (d) The Mid-Atlantic Ridge and the Indian Ocean Ridge (Because the second para casts doubt regarding the applicaion of traditional view to "Mid-Atlantic Ridge and the ridge in the Indian Ocean" and further states that this plate is growing on both sides.
233. (a) Convection usually occurs along lines (Because the second para casts doubt on the traditional theory "because convection does not normally occur along lines")
234. (b) slowly settling foundation (Because the last para tells that "Their floors have probably been sinking for long periods" and "the floor is overlaid by several kilometers of sediment")
235. (b) Several Theories of Ocean Basin Formation (Because the first para tells about the traditional view and the second para gives an alternative theory and the third para suggests some another possibility)
