you, Earth, Local Group, Local Supercluster, solar system, Milky Way Galaxy, universe
you, Earth, Milky Way Galaxy, solar system, Local Group, Local Supercluster, universe
you, Earth, solar system, Milky Way Galaxy, Local Group, Local Supercluster, universe
QUESTION 2
Imagine a planet whose tilt is 90 degrees. How should you describe its seasons?
More extreme than those on Earth.
Constant througout the year.
Longer than those on Earth.
The same as those on Earth.
QUESTION 3
Two observers, one in northern Canada and the other in Australia, are looking at the Moon on the same day. The observer in Canada sees a 3rd quarter Moon. What does the observer in Australia see?
Full Moon
Third quarter Moon
First quarter Moon
New Moon
QUESTION 4
Suppose you are in an elevator that is traveling upward at a constant speed. What force acting on you is strongest, and why?
Gravity is strongest because it is always present.
The elevator pushing you up is strongest because you are moving upward.
The two forces are equal because you aren't accelerating.
You can't tell from the information given.
QUESTION 5
Why do we experience spring tides?
The high tides from the Sun and Moon occur in the same places at a given time.
The Moon pulls on one side of the Earth and the Sun pulls on the other side.
The Sun's tide becomes stronger than the Moon's tide.
The high tides from the Sun and Moon occur in different places at a given time.
QUESTION 6
Is this a sensible statement? Because of their higher frequency, X rays must travel through space faster than radio waves.
No, this is not sensible. X rays and radio waves both travel at the speed of light.
No, this is not sensible. X rays have a lower frequency than radio waves.
No, this is not sensible. Radio waves cannot travel through space because there is no air to carry them.
QUESTION 7
According to the nebular theory, what are asteroids and comets?
They are the shattered remains of collisions between planets.
They are chunks of rock or ice that were expelled from planets by volcanoes.
They are leftover planetesimals that never accreted into planets.
They are the shattered remains of collisions between moons.
They are chunks of rock or ice that condensed long after the planets and moons had formed.
QUESTION 8
The age of the solar system can be established by radioactive dating of
the oldest rocks on Earth
the oldest rocks on the Moon
the atmosphere of Mars
the oldest meteorites
It hasn’t been done yet, but the age of the solar system could be obtained from a sample of Io’s surface.
QUESTION 9
A planet is found orbiting a star like the Sun. The planet has a mass of 0.8 Earth masses and it is 10 AU from its star. Based on our model of solar system formation, what is the most likely composition of this world?
67% rock and 33% metal
95% hydrogen compounds and 5% hydrogen and helium
80% hydrogen and helium, 10% hydrogen compounds, 10% rock and metal
48% rock and metal, 50% hydrogen compounds, and 2% hydrogen and helium
QUESTION 10
Large comets and asteroids (more than 10 km across) that reach the Earth
Can hit the Earth's surface and even affect the global climate.
Are deflected back into space by the atmosphere.
Burn up in the atmosphere and have no effect on the surface.
Cannot exist, since no such object can ever get close to the Earth.
