Quiz: Asteroids Vs Meteoroids Vs Comets! - Quiz

An Asteroid is an object larger than a meteoroid that orbits the sun and is made of rock or metal. Objects larger than 10 meters across used to be called Asteroids. A comet is a body of ice, rock, and dust that can be several miles in diameter and orbits the sun. A Meteoroid is a small rocky or metal object, usually between the size of a grain of sand or a boulder, that orbits the sun.


Questions and Answers
  • 1. 

    A meteoroid originates from which of the following?

    • A. 

      Comet

    • B. 

      Asteroid

    • C. 

      All of the above

    • D. 

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    Meteoroids can originate from both comets and asteroids. Comets are made up of ice, dust, and rocky material, and when they come close to the Sun, the heat causes them to release gas and dust, creating a glowing coma and tail. Asteroids, on the other hand, are rocky and metallic objects that orbit the Sun. When a comet or asteroid enters Earth's atmosphere, it becomes a meteoroid. Therefore, the correct answer is "All of the above" as both comets and asteroids can be the origin of a meteoroid.

    A shooting star is comes from which of the following?

    • A. 

      Asteroid

    • B. 

      Comet

    • C. 

      Meteoroid

    • D. 

      None of the above

    Correct Answer
    C. Meteoroid
    Explanation
    A shooting star comes from a meteoroid. A meteoroid is a small rocky or metallic object that is in space and orbits the sun. When a meteoroid enters Earth's atmosphere and burns up, it creates a streak of light in the sky known as a shooting star or a meteor.

    Which of the following is closer to the Sun?

    • A. 

      Comet

    • B. 

      Meteor

    • C. 

      Meteorite

    • D. 

      Asteroid

    Correct Answer
    D. Asteroid
    Explanation
    Asteroids are closer to the Sun compared to comets, meteors, and meteorites. Asteroids are rocky objects that orbit the Sun, primarily located in the asteroid belt between Mars and Jupiter. Comets, on the other hand, are icy bodies that originate from the outer regions of the solar system and have highly elliptical orbits that can take them much farther from the Sun. Meteors are small particles that burn up in the Earth's atmosphere, while meteorites are the remnants of meteors that survive the journey through the atmosphere and land on the Earth's surface.

    What is the difference between Meteor and Meteoroid?

    • A. 

      A meteor vaporizes before it hits the earth unlike Meteorite

    • B. 

      A meteorite vaporizes before it hits the earth unlike Meteor

    • C. 

      There is no difference

    • D. 

      A meteorite comes from Asteroid while Meteor comes from Meteoroid

    Correct Answer
    A. A meteor vaporizes before it hits the earth unlike Meteorite
    Explanation
    A meteor vaporizes before it hits the earth, unlike a meteorite. This means that a meteor is a bright streak of light that is seen when a meteoroid enters the Earth's atmosphere and burns up due to friction. On the other hand, a meteorite is a meteoroid that survives its passage through the Earth's atmosphere and lands on the Earth's surface. So, the key difference between the two is that a meteor vaporizes in the atmosphere, while a meteorite reaches the Earth's surface.

    Debris comes from which of the following?

    • A. 

      Meteoroid

    • B. 

      Meteor 

    • C. 

      Comet

    • D. 

      Asteroid

    Correct Answer
    C. Comet
    Explanation
    Debris comes from comets. Comets are celestial bodies composed of ice, dust, and rock that orbit the sun in highly elliptical paths. As a comet approaches the sun, the heat causes the ice to vaporize, releasing gas and dust particles. These particles, along with any rocks or other solid materials, create a trail of debris behind the comet. This debris can sometimes enter Earth's atmosphere, resulting in meteor showers.

    Which of the following is the biggest?

    • A. 

      Meteor

    • B. 

      Comet

    • C. 

      Meteoroid

    • D. 

      Asteroid

    Correct Answer
    D. Asteroid
    Explanation
    Asteroid is the correct answer because it is the largest among the given options. While meteors, meteoroids, and comets are all celestial objects, an asteroid is typically larger in size compared to the others. Asteroids are rocky and metallic objects that orbit the sun, and some can be several hundred kilometers in diameter. In contrast, meteors are smaller objects that burn up in the Earth's atmosphere, meteoroids are even smaller fragments of asteroids or comets, and comets are icy bodies that release gas and dust when they come close to the sun.

    Which one of the following is the smallest?

    • A. 

      Meteoroid

    • B. 

      Meteorite

    • C. 

      Comet

    • D. 

      Asteroid

    Correct Answer
    B. Meteorite
    Explanation
    A meteorite is the smallest among the given options. A meteoroid is a small rocky or metallic object that is in space, typically smaller than an asteroid. When a meteoroid enters the Earth's atmosphere and burns up, it is called a meteor. If a meteor survives its passage through the atmosphere and lands on Earth's surface, it is then called a meteorite. Comets and asteroids are larger objects compared to meteorites and meteoroids.

    Which of the following is less likely to cause harm in the event of it landing on earth?

    • A. 

      Asteorite

    • B. 

      Meteorite

    • C. 

      Comeorite

    • D. 

      None of the above

    Correct Answer
    B. Meteorite
    Explanation
    Meteorites are less likely to cause harm in the event of them landing on Earth compared to asteroids and comets. This is because meteorites are smaller fragments that have already survived the intense heat and pressure of entering Earth's atmosphere. They have also lost most of their volatile substances during this process. On the other hand, asteroids and comets are larger objects that can cause significant damage upon impact due to their size and composition.
