Law of Universal Gravitation
This force is responsible for causing a nebula to collapse and eventually form the Sun and planets.
What is gravity?
In a heliocentric model, this object is located at the center of the solar system.
What is the Sun?
Venus is hotter than Mercury because of this characteristic of its atmosphere.
What is a thick atmosphere?
Within the EM spectrum, as the frequency of a wave increases, this property also increases.
What is energy?
This is the specific layer of the atmosphere where all weather occurs
What is the troposphere?
This is the relationship between an object's mass and its gravitational pull.
What is directly related?
This historical model incorrectly depicts the Sun and planets revolving around the Earth.
What is geocentric?
Mercury has significantly more craters than Earth because it has a much thinner one of these.
What is an atmosphere?
These specific waves have the shortest wavelengths and the highest frequencies.
What are gamma rays?
This layer is where most meteors burn up upon entry.
What is the mesosphere?
If two objects have a mass of 7 kg each, their gravitational attraction is greater than two objects of this mass.
What is 5kg?
These devices allow us to visually explore Mars and other planets without endangering humans.
What are remote-controlled devices?
You would weigh more on Jupiter and less on the Moon because weight depends on this property of the planet.
What is mass?
Between Infrared and X-rays, this type of radiation has the longest wavelength.
What is infrared?
The stratosphere is vital because it contains this layer which shields Earth from UV rays
What is the ozone layer?
While a scientific theory explains the why of gravity, this describes the consistent patterns of planetary motion.
What is a scientific law?
Because the atmosphere can affect the precision of these instruments, scientists prefer to build them at high altitudes, far from city lights.
What are satellites?
This term describes the amount of time it takes for a planet to complete one full spin on its axis, often referred to as a "solar day".
What is rotation?
When a star moves away from Earth and its light frequency becomes lower, its wavelength becomes this.
What is longer?
This layer is correctly described as the "initial shield" from the Sun's radiation.
What is the thermosphere?
This is the predicted reaction of a small asteroid when it passes very close to a large planet with a much greater mass.
What is being attracted to the large planet?
This is the primary movement in a heliocentric model.
What is around the Sun?
This term describes a planet's movement along a predictable path around the Sun.
What is an orbit (or revolution)?
Visible light is different from ultraviolet light because it has these longer features.
What are wavelengths?
The order of the layers in the atmosphere from closest to Earth to farthest.
What is troposphere, stratosphere, mesosphere, thermosphere, and exosphere?
