Solar System Formation
Clue: These inner, rocky planets include Mercury, Venus, Earth, and Mars.
Answer: What are terrestrial planets?
Clue: Because it is not a perfect circle, the shape of Earth's orbital path around the sun is mathematically described as this.
Answer: What is an ellipse?
Clue: This specific motion of the Earth on its axis causes the daily cycle of day and night.
Answer: What is rotation?
Clue: This is the specific process that occurs in the core of the Sun, creating the immense energy needed to support life on Earth.
Answer: What is nuclear fusion?
Clue: This type of electromagnetic radiation is what causes sunburns, though much of it is luckily blocked by Earth's atmosphere.
Answer: What is ultraviolet (UV) light?
Clue: This is the widely accepted scientific model explaining how our solar system formed from a collapsing, spinning cloud of gas and dust.
Answer: What is the Solar Nebular Theory?
Clue: Kepler's 2nd Law states that a planet's orbital speed increases when its orbit brings it closer to this celestial body.
Answer: What is the Sun?
Clue: Differences in sunlight intensity and our changing weather patterns throughout the year are caused by Earth's revolution and this specific physical feature of the planet.
Answer: What is its axial tilt?
Clue: During nuclear fusion in the sun, two atoms of this lightest element combine together.
Answer: What is hydrogen?
Clue: On the electromagnetic spectrum, shorter wavelengths, like blue light, possess more of this than longer wavelengths, like red light.
Answer: What is energy?
Clue: These massive outer planets, which include Jupiter and Saturn, are primarily composed of gases and ice.
Answer: What are Jovian planets (or gas/ice giants)?
Clue: This mathematical term describes the "flatness" or the amount by which a planet's orbit deviates from a perfect circle.
Answer: What is eccentricity?
Clue: These extreme tides occur during the full and new moon phases when the Earth, Moon, and Sun are aligned.
Answer: What are spring tides?
Clue: When hydrogen atoms are fused together in the Sun's core, they form this slightly heavier element.
Answer: What is helium?
Clue: This is the specific type of electromagnetic radiation that successfully passes through the atmosphere to make up the majority of the light reaching Earth's surface.
Answer: What is visible light?
Clue: Pluto is classified as this type of celestial body because it is spherical but has not cleared its neighboring orbital region of other debris.
Answer: What is a dwarf planet?
Clue: This point is the center of mass around which two or more orbiting objects, like the Earth and the Moon, balance and revolve.
Answer: What is the barycenter?
Clue: These specific tides, which have the smallest tidal range, happen during the first quarter and third quarter moon phases.
Answer: What are neap tides?
Clue: During the Sun's nuclear fusion process, it is specifically this positively charged subatomic particle from the hydrogen atoms that combines.
Answer: What is a proton?
Clue: Earth's magnetic field protects the planet by deflecting and blocking out this highest-energy, shortest-wavelength radiation from space.
Answer: What is gamma radiation?
Clue: According to the Solar Nebular Theory, nearly all planets in our solar system revolve around the Sun and rotate on their axes in this specific direction.
Answer: What is counterclockwise?
Clue: Kepler's 3rd Law explains that the square of a planet's orbital period is proportional to the cube of this measurement.
Answer: What is the semi-major axis (or distance from the sun)?
Clue: The daily pattern of tidal heights is ultimately determined by the Moon's phase and this specific time-related factor as Earth turns.
Answer: What is the time of day?
Clue: After energy is produced in the Sun's core, it travels outward into space only after passing through these two specific layers of the Sun.
Answer: What are the radiative and convective zones?
Clue: This is the correct order of Infrared, Visible, and Ultraviolet waves when categorizing them from lowest energy to highest energy.
Answer: What is Infrared, Visible, Ultraviolet?
