Question 1: Science and Technology

A meteor is

aa rapidly moving star
ba piece of matter which has entered the earth’s atmosphere from outer space
cpart of a constellation
da comet without a tail

AnswerThe answer is (b).

A meteor is the streak of light seen when a small piece of rock or metal from space, a meteoroid, enters the earth's atmosphere at high speed and burns up through friction. If a piece survives and lands on the ground it is called a meteorite. Remember the sequence: meteoroid in space, meteor in the atmosphere, meteorite on the ground. Stars and comets are quite different bodies.

Why each option is right or wrong
  • (a) Meteors look like shooting stars but are not stars; they are small bodies burning up in the atmosphere.
  • (b) Right: matter from outer space entering the atmosphere and glowing as it burns.
  • (c) A constellation is a pattern of stars; a meteor is not part of one.
  • (d) A comet without a tail is still a comet, an icy body in orbit; a meteor is a rocky or metallic fragment.
