QuestionAnswer
Open Hint for Question 1 in a new window Which of the following lists the planets of our solar system in the correct order from closest to farthest from the Sun? Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Suppose you view the solar system from high above Earth's North Pole. Which of the following statements about planetary orbits will be true? All the planets orbit counterclockwise around the Sun
Which of the following statements about our Sun is not true? The Sun's diameter is about 5 times that of Earth.
Which of the following is not true of Mercury? It has been studied closely by several NASA spacecraft.
Which of the following statements about Mars is not true? We could survive on Mars without spacesuits, as long as we brought oxygen in scuba tanks
The planet in our solar system with the highest average surface temperature is _________. Venus
The terrestrial planets in our solar system are _________. Mercury, Venus, Earth, and Mars.
The jovian planets in our solar system are _________. Jupiter, Saturn, Uranus, and Neptune.
Which jovian planet does not have rings? All the jovian planets have rings
Which moons are sometimes called the Galilean moons? The four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto.
The Cassini mission to Saturn consists of: An orbiter that orbits Saturn and a probe that descended to the surface of Titan.
Which planet (besides Earth) has been visited by the largest number of robotic spacecraft? Mars
When we say that jovian planets contain significant amounts of hydrogen compounds, we mean all the following chemicals except _________. carbon dioxide
In essence, the nebular theory holds that _________. our solar system formed from the collapse of an interstellar cloud of gas and dust
According to modern science, what was the approximate chemical composition of the solar nebula? 98% hydrogen and helium, 2% everything else
The terrestrial planets are made almost entirely of elements heavier than hydrogen and helium. According to modern science, where did these elements come from? They were produced by stars that lived and died before our solar system was born.
According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size? It got hotter, its rate of rotation increased, and it flattened into a disk.
Which of the following types of material can condense into what we call ice at low temperatures? Hydrogen compounds
According to our present theory of solar system formation, which of the following lists the major ingredients of the solar nebula in order from the most abundant to the least abundant? hydrogen and helium gas; hydrogen compounds; rock; metal
What do we mean by the frost line when we discuss the formation of planets in the solar nebula? Therefore planetesimals were built only of metal and rock within the frost line, but beyond the frost line they included ices along with metal and rock.
What do we mean by accretion in the context of planet formation? The growth of planetesimals from smaller solid particles that collided and stuck together
According to our theory of solar system formation, what are asteroids and comets? Leftover planetesimals that never accreted into planets
What do we mean by the period of heavy bombardment in the context of the history of our solar system? The first few hundred million years after the planets formed, which is when most impact craters were formed
What is the giant impact hypothesis for the origin of the Moon? The Moon formed from material blasted out of the Earth's mantle and crust by the impact of a Mars-size object.
Suppose you start with 1 kilogram of a radioactive substance that has a half-life of 10 years. Which of the following statements will be true after 20 years pass? You'll have 0.25 kilogram of the radioactive substance remaining.
According to modern scientific dating techniques, approximately how old is the solar system? 4.5 billion years
What is an "extrasolar planet"? A planet that orbits a star that is not our own Sun
In essence, most of the extrasolar planets discovered to date have been found by: Observing a star carefully enough to notice that it is experiencing a gravitational tug caused by an unseen planet.
