What is the main force that keeps a planet traveling along a curved path around the sun instead of traveling in a straight line past the sun?
the force of gravity between the planet and the Sun
the force of gravity between the planet and the Earth
the magnetic force between the planet and the Earth
the magnetic force between the planet, the Sun, and the other planets
Which of the following is a physical property of the Sun?
it's the same size as the moon
it rotates but is stationary in space
it's made of burning solid rock
it's made of hydrogen and helium gas
The gaseous, outer planets
are less dense than the inner, rocky planets
have less gravitational pull than the inner, rocky planets
are much smaller than the inner, rocky planets
do not have moons like the inner, rocky planets
If objects in space move at a constant rate and direction unless acted upon by an unbalanced force, then why do planets orbit the sun?
the magnetic force of distant stars pushes the planets into a curved path
the force of gravity between planets keeps them on a path, preventing them from leaving the solar system
the force created by the nuclear fusion of the hydrogen in the Sun curves the planet's paths.
the inertia of the planets and the gravitational pull of the Sun cause the planets to move in curved paths.
Which of the following statements is true about meteoroids, asteroids, and comets?
meteoroids have a tail and the other two do not
meteroids and asteroids are made of rock and comets are made of gases
all of them orbit the sun, and comets may enter the earth's atmosphere
they are all made of rock
What is so significant about the Space Shuttle in terms of all other US spacecraft?
the shuttle could leave Earth's orbit
the shuttle could launch from a runway like an airplane
the shuttle landed like an airplane and could be reused
the shuttle stayed in orbit around the Earth forever
Which of the following is an advantage of unmanned missions such as space probes, over manned missions?
unmanned missions require life support systems
unmanned missions are able to change and adapt to unexpected situations
unmanned missions may continue longer than a human life span
unmanned missions risk human lives
Which of the following statements is true about our solar system?
the gas planets are closer to the sun
the planets are arranged in order of increasing size
the solid planets are much larger than the gas planets
the solid planets are closer to the sun
Which statement is true about Venus?
It is a gaseous, outer planet
It is the 1st planet from the Sun, followed by Mercury
it is the 2nd planet from the Sun, followed by Earth
it is closest to Mars
