Exam 8: The Other Terrestrial Planets

The approximate pressures of the atmospheres at the surfaces of Mercury, Venus, and Mars, in terms of the pressure at the surface of Earth (known as 1 atmosphere), are, respectively,

The "snow" that occasionally falls in and near the polar regions of Mars consists of

Which of these does NOT describe an argument in favor of the presence of active volcanoes on Venus at the present time?

Two observed features on Mars appear to lead to contrary geological conclusions-the appearance of massive, solitary volcanoes, apparently caused by hot spots under the planet's surface, and the discovery of a long, deep rift valley across the planet. Why are the two features a contradiction?

The density of Mercury is about the same as that of Earth, but Mercury contains a larger proportion of iron. How is this possible?

Evidence of past water on Mars comes from each of these EXCEPT

The surface features and overall topology of Venus have been determined primarily by

At greatest elongation, the Earth-Venus line makes an angle with the Sun-Venus line that is

Mercury's atmosphere is

Craters on Mars have flatter bottoms and their rims appear to be more worn down than those on either Earth's Moon or Mercury. What has caused this wear?

What role has methane played in the search for life on Mars?

Spacecraft measurements indicate that the surface of Venus is dominated by

What is the observed feature that suggests that Mercury's iron core is at least partly molten?

The origin of the Martian magnetic field appears to be

The albedo, or fraction of light reflected from the surface, of Mercury is

Seasons on Mars last nearly twice as long as those on Earth because

Earth's average density (5520 kg/m³) is slightly higher than that of Mercury (5430 kg/m³) because

In what way was the production of the major volcanoes on Mars different from the production of the Hawaiian Islands on Earth?

How was water ice discovered near Mercury's poles?

In what way was the production of the major volcanoes on Mars similar to the production of the Hawaiian Islands on Earth?
