Among the bodies in our solar system are asteroids, moons, planets and the Sun. Which statement least supports the theory that gravity helped form our solar system?
The Sun consists primarily of gases.
Many objects in space are spherical in shape.
Planets revolve around an object of greater mass.
Planets form by small masses combining into larger masses.
How many layers exist of the Sun?
1
2

4
How do asteroids and comets differ from each other?
Asteroids are composed mostly of rock and metal, while comets are made of ice and dust.
Asteroids lose mass over time, while the mass of a comet remains constant.
Asteroids orbit the Sun at a variety of angles, while the orbits of comets are close to the ecliptic plane.
Asteroids are generally found at the edge of the Solar System, while comets are typically found between Mars and Jupiter.
Just before the power failure, data from a spacecraft indicated a reduction in its velocity that was too rapid to be explained by just the Sun's gravitational pull. Which of the following is the best conclusion based on the unexplained data?
The instruments measuring Pioneer 10's velocity malfunctioned.
The spacecraft was slowed by a force other than gravity.
The law of universal gravitation is incorrect and should be revised.
The data collected regarding the Sun's gravitational force is incorrect.
Some students sets up a telescope to photograph the Sun during a total solar eclipse. This type of eclipse occurs when the Moon passes between the Sun and Earth. Which layer of the Sun can be viewed during a total solar eclipse?
convection zone
core
corona
sunspots
Why do Venus & Mercury not have moons?
Venus and Mercury have a gravitational pull that is weaker than the gravitational pull of the Sun.
Venus and Mercury travel too quickly around the Sun to attract moons.
Venus and Mercury are too cold to keep moons in orbit.
Venus and Mercury have no gravity.
What do sunspots and solar flares have in common?
They both originate in the radiation zone of the Sun's interior.
They both originate from areas of intense magnetic activity.
They both have higher temperatures than the material around them.
They both release energy from the Sun's core into the convection zone.
Which sequence places the layers of the Sun in the correct order, from innermost to outermost?
convection zone → core → radiation zone
radiation zone → convection zone → core
core → radiation zone → convection zone
convection zone → radiation zone → core
Why did scientist accept heliocentrism before new info came out?
One scientist was the smartest.
A university was still studying the effects.
They thought they knew everything.
New technology such as the telescope became available, allowing astronomers to gather extensive data about the movement of stars.
