Question

Which statement is not true about the polar caps of Mars? They contain a residual cap which remains frozen. They shrink and grow with the seasons on Mars. They are both predominantly water ice with a small amount of carbon dioxide. They cause variations in the atmospheric pressure. They store a large fraction of the gas that was once contained in the atmosphere of Mars. Why were Martian volcanoes able to grow so large? Due to greater amounts of lava available Due to the lack of a significant Martian atmosphere Due to Mars's weaker gravity Due to Mars's hotter interior Due to the earlier formation of Mars compared to other planets What property of Jupiter has had the greatest effect on its retaining its very thick atmosphere? Rotation Mass Distance from the Sun Magnetic field

Explanation / Answer

question 10: They cause variations in the atmospheric pressure. explanation: polar caps leave carbondioxide during spring that has no relation in atmospheric pressure. question11: due to greater amount of lava available. explanation: due to no movement of crustal plates in mars, crust remains stationary and the lava keeps flowing which leads to its larger size. question 12: magnetic field explanation: it has strong magnetic field due to metallic hydorgen present in it.
