How Well Do You Know Meteoroid?

2.

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

Meteorite
Meteorite shower
Comet
Meteoroid series

Correct Answer

A. 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.

Meteoroids come from

Asteroid belt
Comets
Moon
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.

Meteoroids contain which of the following?

Magnesium and uranium
Iron and nickel
Argon and nickel
Tin and zinc

Correct Answer

A. 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.

The fastest meteoroid moves at about

31km per second
40km per second
42km per second
35km per second

Correct Answer

A. 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 remaining portion of a meteoroid that hits the earth is called

Comet
Chrondite
Meteorite
Asteroid

Correct Answer

A. 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.

Stone meteoroids contain greenlike inclusions known as

Achondrites
Planets
Chondrules
Comet

Correct Answer

A. 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.

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

Meteor
Meteorite
Comet
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 meteoroid was described as a solid object moving in an interplanetary space in the year

1960
1961
1962
1959

Correct Answer

A. 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.

The first case of 'hit by meteoroid' occurred in

1950
1951
1955
1954

Correct Answer

A. 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.
