Question
1.Choose the correct statement about earthquake waves.
a.The vibrations in the P-waves and S-waves create gravitational waves.
b. Both P-waves and S-waves travel at the same velocity which does not depend on the density of material through which they are traveling.
c. Seismic P-waves are blocked by Earth's liquid core and S-waves travel throughout the planet.
d. A Richter Scale is a scientific machine used to measure earthquakes.
e. Seismic waves follow curved paths because of differences in the density and composition of the material in Earth's interior.
2.The magnetic field of Venus is
a.comparable to the magnetic field of Ur-an-us.
b.almost nonexistent.
c.the strongest of the magnetic fields of the terrestrial planets.
3.This is attributed to
a.the tilt of the rotation axis of Venus.
b.the 243 day rotation period of Venus.
c.the dense carbon dioxide atmosphere of Venus.
4.Which of the following statements is true about plate tectonics?
a.Earth's rapid rotation and tidal forces from the Moon and Sun causes the continental plates to drift and collide.
b.Continental drift on Earth is caused by the slow precession of Earth's spin axis.
c.The San Andreas Fault is part of the Mid-Atlantic Ridge where two crustal plates slide past each other, creating significant and sizeable earthquakes.
d.The surface of the Earth consists of individual rigid crustal plates floating on the underlying mantle.
e.Two crustal plate boundaries can easily slide past each other because of the presence of seawater.
5. Volcanoes on Mars are enormous because
a.there is very little atmosphere to erode them away.
b.Mars is close enough to Jupiter that the tidal forces between the planets result in increased volcanism on Mars.
c.Mars is the most geologically active planet in the Solar System.
d.the lack of plate tectonics means that volcanoes stay over a "hot spot" for billions of years.
6.According to the giant impact hypothesis, how did the Moon form?
a.A Mars-sized object smashed into the molten proto-Earth, resulting in a larger Earth and debris that coalesced to form the Moon.
b.A large iron asteroid collided with the rocky Earth during the late heavy bombardment. The asteroid carried material away from the Earth which accreted onto the asteroid and formed the Moon.
c.A jovian planet was struck by a large asteroid and split into two smaller bodies which became the Earth and the Moon.

1 Seismic waves follow curved paths because of differences in the density and composition of the material in Earth's interior.
2 .almost nonexistent.
3 .the 243 day rotation period of Venus.
because of its slow rotation, it cant generate magnetic field
