Part I This section comprises 60 multiple-choice questions. Each question is worth 1/2 mark.

Make sure that you have properly filled in your student ID# and the version number of the exam on the grading sheet. [30 marks] This is Version 1 1. About 70% of all earthquakes occur along the subduction zones. About 10% occur within the interior of tectonic plates well away from plate margins. Most of the remainder occur 1. where lithospheric plates are either separating or slipping past each other. 2. where bubbles rising through Earth's mantle break through the crust. 3. at the boundary between the Earth's mantle and core. 4. where impacts caused by asteroids and large meteoroids have weakened the crust. 5. in the most populated regions of Asia, the Middle East and North Africa. 2. We have, since the Apollo astronauts installed laser retro-reflecting mirrors on the surface of the Moon, measured the lengthening orbital period and (hence) the increasing distance between Earth and the Moon. The fact that the Moon is slowly retreating from the Earth at about 3.8 cm/yr is a consequence of: 1. a continuing transfer of mass from the Earth to the moon through quantum evaporation. 2. a natural evolution of planetary satellites towards becoming independent planets themselves. 3. a transfer of angular momentum from the Earth’s rotation to the moon’s orbital revolution as a consequence of tidal friction on the Earth. 4. moonquakes ”. 5. the Sun's dominant gravitational force which is slowly pulling the Moon away from Earth. 3. Which of the following volcanoes is not a shield volcano ? 1. Olympus Mons on Mars. 2. Maat Mons on Venus. 3. Mauna Loa on Earth. 4. Mt. Fuji on Earth. 5. Sif Mons on Venus. 4. Which among the following planetary, solar-planet or planet-moon pairs does not show spin-orbit resonant coupling? 1. Io in orbit about Jupiter. 2. Mercury in orbit about the Sun. 3. The Moon in orbit about Earth. 4. Co-orbiting Pluto and Charon. 5. Neptune and Uranus in orbit about the Sun. 5. The pressure of Mars ' atmosphere at its surface is 1. about 0.01 (1- one hundredth) that of the Earth's atmospheric pressure. 2. almost exactly the same as the Earth's atmospheric pressure. 3. just about 10 times the Earth's atmospheric pressure. 4. approximately 100 times the Earth's atmospheric pressure. 5. has not yet been determined. Note: another 55 multiple-choice questions followed these 5 questions on the 2007 Winter sessions exam. These questions will not be published.
