Exam 8: The Other Terrestrial Planets

The Caloris Basin is an immense impact crater on Mercury, which is unusual in that the opposite side of the planet shows jumbled terrain that resulted from shock waves created by the impact. This combination has also been found

On which object would one find the great valley system Valles Marineris?

What evidence have some scientists claimed for ancient life on Mars (although the hypothesis has been strongly disputed by many other scientists)?

There are traces of oxygen in Mercury's atmosphere. The source of this is believed to be

In the mapping of Venus by the orbiting Magellan spacecraft, what parameter was measured by the sensors in order to produce three-dimensional maps of the planet's surface?

On a topographical map of Venus, how many large "continents" of high ground rise above the flat plains?

Which of these hypotheses has NOT been proposed as a mechanism for resurfacing Venus (and periodically eradication of the craters)?

The spacecraft that has provided the MOST detailed understanding of the Martian surface to date is

What is so special about Aphrodite Terra and Ishtar Terra on Venus that they are distinguished as being continents?

The equator of Mars is tilted with respect to its orbital plane, so Mars

"This planet has a very hot solid surface, it is cloud-shrouded, and it has a dense carbon dioxide atmosphere." Which of the planets fits this description?

Several aspects of Mars render it hostile to life on the planet. Which of these components is NOT one of these factors?

Which spacecraft and technique has given planetary scientists the most extensive information about the overall surface of Venus?

Mercury, unlike the Moon, has large crater-filled plains rather than maria. The reason is thought to be that

The Martian magnetic field is

The geology and geography of the surface of Venus is BEST described as

Spacecraft measurements near Venus indicate that the planet has

What caused the long, meandering scarps (cliffs) that can be seen on Mercury?

Which planet MOST resembles the Moon in visible surface features and atmosphere?

Which of these is NOT one of the known locations of water on Mars?
