The "Hair" Out There________________ _____________ showed that comets actually traveled far beyond the moon.
Explanation
Tycho Brahe was a Danish astronomer known for his accurate and detailed observations of the celestial bodies. His observations of comets provided evidence that they traveled beyond the moon, challenging the prevailing belief at the time that comets were atmospheric phenomena. Therefore, the mention of Tycho Brahe in the context of comets traveling far beyond the moon supports the statement that "The 'Hair' Out There" showed that comets actually traveled far beyond the moon.Rate this question:

What Goes Around Comes AroundThe famous Bayeux Tapestry, which commemorates the Norman Conquest of England in 1066, depicts an image of ____________________ comet bright in the sky before the Battle of Hastings.
Explanation
The correct answer is "Halley's". The question is asking for the correct spelling of the comet that is depicted in the Bayeux Tapestry. The comet referred to in the tapestry is Halley's Comet, which is a well-known comet that appears in Earth's skies approximately every 76 years.Rate this question:
- 10.
What Goes Around Comes Around____________________ ___________________ developed a theory that comets reappear. He predicted the comet's next appearance.
Explanation
Edmund Halley developed a theory that comets reappear and predicted the comet's next appearance.Rate this question:
- 11.
What Goes Around Comes AroundHalley’s comet reappears every ________________ years. Its next appearance is in 2061.
Explanation
Halley's comet is a famous periodic comet that orbits the sun and reappears in the Earth's sky approximately every 76 years. This means that after every 76 years, the comet completes its orbit and returns to a point where it becomes visible from Earth again. The statement "Its next appearance is in 2061" confirms this periodicity, indicating that the comet will be visible again in 2061, which is 76 years after its last appearance.Rate this question:
- 12.
Forecast: Showers?When a comet crosses Earth's path, _______________________ showers, from the comet's debris strike the atmosphere.
Explanation
When a comet crosses Earth's path, meteor showers occur as the debris from the comet strikes the Earth's atmosphere.Rate this question:
- 13.
Forecast: Showers?The Perseid meteor shower occurs every year between _________________ 9 and 13 when the Earth passes through the orbit of the Swift-Tuttle comet.
Explanation
The Perseid meteor shower occurs every year between August 9 and 13 when the Earth passes through the orbit of the Swift-Tuttle comet.Rate this question:
- 14.
Forecast: Showers?Comets are brightest when they are near the ________________.
Explanation
Comets are brightest when they are near the Sun because the Sun's heat causes the comet's icy nucleus to vaporize and release gas and dust, forming a glowing coma and tail. As the comet gets closer to the Sun, the intensity of solar radiation increases, resulting in a more pronounced and brighter display. The Sun's proximity is crucial for the comet's visibility and the spectacular appearance it exhibits.Rate this question:
- 15.
A Crash Course?Sixty-five million years ago, ______________ percent of all species then living on Earth disappeared within a very short time.
Explanation
The statement mentions that 65 million years ago, a certain percentage of all species disappeared within a short time. The answer provided, 70% or 70, indicates that 70 percent of all species then living on Earth disappeared during that period.Rate this question:
- 16.
A Crash Course?There is a 65-million-year-old crater from an impact of similar magnitude just off the coast of ____________________ in the Yucatan Peninsula.
Explanation
The correct answer is Mexico because the question states that there is a 65-million-year-old crater off the coast of a place in the Yucatan Peninsula. Since Mexico is located in the Yucatan Peninsula, it is the most logical choice for the answer.Rate this question:
- 17.
A Crash Course?Is it likely that an asteroid or comet will hit the Earth in the next few 100 years?
- A.
YES
- B.
NO
Correct Answer
B. NOExplanation
The answer is "NO" because the question asks if it is likely for an asteroid or comet to hit the Earth in the next few 100 years. The word "likely" implies a probability or chance, and based on current scientific knowledge and observations, the likelihood of such an event occurring in the next few 100 years is low. While it is possible for asteroids or comets to collide with Earth, the probability of it happening within a specific time frame is considered to be very low.Rate this question:

Famous CometsComet ______________ is perhaps the most famous comet in history
Correct Answer
HalleyExplanation
Halley is the most famous comet in history. It is widely known for its periodic appearance in Earth's sky every 76 years. Named after the astronomer Edmond Halley, who predicted its return, Halley's Comet has been observed and documented for centuries. Its distinct and recognizable appearance, along with its predictable orbit, has made it a subject of fascination and study. The comet has been mentioned in historical records, literature, and popular culture, solidifying its status as the most famous comet in history.Rate this question:
- 23.
Famous CometsEach time Halley's comet's orbit approaches the Sun, its 15-km (9-mile) nucleus sheds about 6 m (7 yards) of _______ _________ _________ into space. This debris forms an orbiting trail that, when falling to Earth, is called the Orionids meteor shower.
Correct Answer
ice and rockExplanation
When Halley's comet approaches the Sun, the heat causes the ice in its nucleus to vaporize, releasing gas and dust particles. This process, known as sublimation, causes the comet to shed about 6 meters of ice and rock into space. This debris forms a trail along the comet's orbit, and when the Earth passes through this trail, the particles enter our atmosphere and burn up, creating a meteor shower known as the Orionids.Rate this question:

Famous CometsBetween July 16 and July 22, 1994, more than _________ fragments of Comet Shoemaker-Levy 9 collided with the planet Jupiter.
Correct Answer
20Explanation
Between July 16 and July 22, 1994, more than 20 fragments of Comet Shoemaker-Levy 9 collided with the planet Jupiter. This event was significant because it was the first observed collision between two solar system objects. The impacts created large fireballs and released enormous amounts of energy, leaving dark scars on Jupiter's atmosphere that lasted for weeks. The collision of Comet Shoemaker-Levy 9 with Jupiter provided valuable insights into the dynamics of our solar system and the potential impact hazards that exist in space.Rate this question:
