Chapter #7 Flashcards
Which of the following is NOT icy in composition?
asteroids
In the conventional scenario, during the phase of planet formation caused the jovian planets to form?
core-accretion
Which of the following is considered “interplanetary matter”?
Comet Hale-Bopp
The moons of the jovian planets formed by which two processes?
accretion and capture
The planet’s orbital period is
the time it takes to return to the same location in the sky, relative to the Sun
A meteorite is
a chunk of space debris that struck the ground
The jovian planets
all have rings arounf their equators
What is true about solar system densities?
The denser planets lie closer to the Sun
Which spacecraft gave or is giving us our best information about Mercury?
Mariner 10
A gravitational “sling-shot”:
chnages the speed and direction of a spacecraft nearing a massive planet
Our best close-up views of the jovian moons came from the many passes by
Galileo
Most asteroids are found
between the orbits of Mars and Jupiter
Which of these is NOT a characteristic of the solar nebula theory
Larger planets should form closer to their star, where there is more debris
What factor caused different planets to form out of different types of material?
The variation in temperature throughout the solar nebula; the higher the temperature, the lower the percentage of light elements in the forming planet.
What is the goal of comparative planetology?
to determine the origin and evolution of the solar system
