How Well Do You Know Meteoroid? - Quiz

A meteoroid is a piece of stony debris which travels in outer space. It travels into the earth atmosphere from which small particles enter the earth.


Questions and Answers
  • 1. 

    Meteoroids contain which of the following?

    • A.

      Magnesium and uranium

    • B.

      Iron and nickel

    • C.

      Argon and nickel

    • D.

      Tin and zinc

    Correct Answer
    B. Iron and nickel
    Explanation
    Meteoroids are small rocky or metallic objects that orbit the sun. They are composed primarily of iron and nickel, which gives them their characteristic metallic appearance. Magnesium and uranium are not typically found in meteoroids, and argon and nickel are not the main components. Tin and zinc are also not commonly found in meteoroids. Therefore, the correct answer is iron and nickel.

    Meteoroids come from

    • A.

      Asteroid belt 

    • B.

      Comets

    • C.

      Moon

    • D.

      Chondrules

    Correct Answer
    A. Asteroid belt 
    Explanation
    Meteoroids come from the asteroid belt, which is a region of space located between the orbits of Mars and Jupiter. The asteroid belt is populated by numerous small rocky objects, known as asteroids, which are remnants from the early formation of the solar system. These asteroids can collide with each other, causing fragments to break off and become meteoroids. Meteoroids are small rocky or metallic objects that travel through space and can enter Earth's atmosphere, creating meteor showers or occasionally impacting the Earth's surface as meteorites. Comets, the moon, and chondrules are not sources of meteoroids.

    The fastest meteoroid moves at about 

    • A.

      31km per second

    • B.

      40km per second

    • C.

      42km per second

    • D.

      35km per second

    Correct Answer
    C. 42km per second
    Explanation
    Meteoroids are small rocky or metallic objects that move through space. They are known to travel at extremely high speeds. The given answer, 42km per second, is the fastest among the options provided. This indicates that meteoroids can move at incredible velocities, highlighting their ability to cover vast distances in a short period of time.

    The entry of meteoroids into the earth's atmosphere produce a light in the sky known as 

    • A.

      Meteor

    • B.

      Meteorite

    • C.

      Comet

    • D.

      Chondrite

    Correct Answer
    A. Meteor
    Explanation
    When meteoroids enter the Earth's atmosphere, they create a streak of light in the sky known as a meteor. This occurs due to the intense heat generated by the friction between the meteoroid and the Earth's atmosphere. Meteoroids are small rocky or metallic objects that originate from asteroids or comets and are typically smaller than a kilometer in size. Once a meteoroid survives its passage through the atmosphere and lands on the Earth's surface, it is then called a meteorite. Comets, on the other hand, are icy bodies that release gas and dust to form a glowing coma and tail when they approach the Sun. Chondrite refers to a type of stony meteorite that contains small spherical particles called chondrules.

    A meteor is also referred to as 

    • A.

      Falling star 

    • B.

      Comets

    • C.

      Chrondrits

    • D.

      Asteroid

    Correct Answer
    A. Falling star 
    Explanation
    A meteor is also referred to as a falling star because when a meteoroid enters the Earth's atmosphere and burns up, it creates a streak of light in the sky that resembles a star falling. This phenomenon is commonly observed and has been associated with wishes and luck, hence the term "falling star." Comets, chrondrits, and asteroids are different celestial bodies and are not synonymous with meteors.

    The remaining portion of a meteoroid that hits the earth is called 

    • A.

      Comet

    • B.

      Chrondite

    • C.

      Meteorite

    • D.

      Asteroid

    Correct Answer
    C. Meteorite
    Explanation
    A meteoroid is a small rocky or metallic object that orbits the sun. When a meteoroid enters the Earth's atmosphere and survives the intense heat and friction, it is called a meteor. However, if a meteoroid does not completely burn up and reaches the Earth's surface, it is then called a meteorite. Therefore, the correct answer is meteorite.

      1954

    Correct Answer
    D. 1954
    Explanation
    In 1954, the first recorded case of someone being hit by a meteoroid occurred. This event marked the first documented instance of a meteoroid striking a human being.

    Stone meteoroids contain greenlike inclusions known as 

    • A.

      Achondrites

    • B.

      Planets

    • C.

      Chondrules

    • D.

      Comet

    Correct Answer
    C. Chondrules
    Explanation
    Chondrules are small, round grains found in stone meteoroids. They are composed of various minerals and are believed to have formed in the early solar system, possibly as a result of high-temperature melting and rapid cooling. Chondrules are important in studying the formation and evolution of the solar system, as they provide valuable information about the conditions present during their formation.

    A meteoroid was described as a solid object moving in an interplanetary space in the year

    • A.

      1960

    • B.

      1961

    • C.

      1962

    • D.

      1959

    Correct Answer
    B. 1961
    Explanation
    In 1961, a meteoroid was described as a solid object moving in interplanetary space. This suggests that prior to 1961, the concept or understanding of a meteoroid as a solid object in interplanetary space was not yet established. Therefore, 1961 is the most likely year when this description was first made.

    A series of meteoroids that are slightly apart and and originate from the same fixed point is called 

    • A.

      Meteorite

    • B.

      Meteorite shower

    • C.

      Comet

    • D.

      Meteoroid series 

    Correct Answer
    B. Meteorite shower
    Explanation
    A series of meteoroids that are slightly apart and originate from the same fixed point is called a meteorite shower. This term refers to the phenomenon where multiple meteoroids, which are small rocky or metallic objects, enter the Earth's atmosphere and burn up, creating a streak of light in the sky. These meteoroids come from the same source, such as a comet or asteroid, and appear to radiate from a specific point in the sky.
