Questions 63 to 65 are based on the following passage:
Meteor is a bright streak of light that appears brightly in
the sky. Observers often call meteors shooting stars or
falling stars because they look like stars from the sky.
People sometimes call the brightest meteors fireballs. A
meteor appears when a particle or chunk of metallic or
stony matter called a meteoroid enters the earth’s
atmosphere from outer space. Air friction heats the
meteoroid so that it grows and creates a shining trail of
gases and melted meteoroid particles. The gases include
vaporized meteoroid material and atmospheric gases that
heat up when the meteoroid passes through the atmosphere.
Most meteors glow for about a second.
Most meteoroids disintegrate before reaching the earth. But
some leave a trail that lasts several minutes. Meteoroids
that reach the earth are called meteorites. Millions of
meteors occur in the earth’s atmosphere every day. Most
meteoroids that cause meteors are about the size of a
pebble. They become visible between about 40 and 75 miles
(65 and 120 kilometers) above the earth. They disintegrate
at altitudes of 30 to 60 miles (50 to 95 kilometers).
Meteoroids travel around the sun in a variety of orbits and
at various velocities. The fastest ones move at about 26
miles per second (42 kilometers per second). The earth
travels at about 18 miles per second (29 kilometers per
second). Thus when meteoroids meet the earth’s atmosphere
head-on, the combined speed may reach about 44 miles per
second (71 kilometers per second).
The earth meets a number of streams (trails) or swarms
(clusters) of tiny meteoroids at certain times every year.
At such times, the sky seems filled with a shower of
sparks, which is called meteor shower. Streams and swarms
have orbits like those of comets and are believed to be
fragments of comets.
