Gravity Rules
Every object pulls on every other object in space, what is this force?
Gravity
What solar system model places Earth at the center?
Geocentric
This planet supports life because it has liquid water and a suitable atmosphere.
Earth
Scientists use this remote-controlled vehicle to explore Mars.
Rover
As frequency increases, wavelength does this.
Decreases
What are the two factors that affect gravitational force?
Mass and Distance
What solar system model places the sun at the center?
Heliocentric
This planet is hotter than Mercury because of its thick atmosphere and greenhouse effect.
Venus
Would a scientist want a telescope close to a city or far away?
Far Away
As frequency increases, energy does this.
Increases
If two asteroids were to move closer to one another what would happen to the gravitational force?
Increase
What does the prefix Helio mean?
Sun
Compared with Earth, Saturn takes much more time to complete a revolution, Why?
Farther from Sun
Are observatories built typically at sea level or high above it?
Above it
This type of electromagnetic radiation has the greatest energy.
Gamma Rays
A comet that flies close to the sun changes direction due to what property of the sun?
Large Mass
Modern evidence supports what model of the solar system?
Heliocentric
Planets that are larger in mass tend to have shorter these?
Rotations
Why can rovers explore dangerous environments better than astronauts?
They dont risk human life
This type of radiation has longer wavelengths: ultraviolet or visible light?
Visible Light
Two objects are the same distance apart. Object pair A has masses of 5 kg each, pair B has masses of 10 kg each. Which pair has greater gravitational attraction?
Pair B
Why did science change from believing in the Geocentric Model to the Heliocentric Model
New Evidence
Are the inner or outer planets more dense? Why is this?
Inner made of rocks
What is the benefit of placing a telescope in space instead of on Earth?
Lack of atmospheric distortion
A star moving away from Earth shows lower frequency light. Its wavelength becomes this.
Longer
