Identify the true statement(s) for comets:
-
Those are messengers of disaster
-
Many comets appear after a fixed time interval
-
Occurrance of comets is a natural phenomenon
-
The tail of the comet is always directed towards the sun
Occurance of comets is a natural phenomenon and there is nothing superstitious about it. Many comets appear after fixed time interval for example, Halley"s comet which appears once in every 76 years.

Meteors are small objects that sometimes enter the Earth"s atmosphere. However, due to the high speed of the meteor friction is created between its surface and Earth"s atmosphere causing it to heat up. Thus it glows and evaporates quickly and appears for a very short period of time as a bright streak of light.
Comets revolve around the Sun:
-
in a highly elliptical orbit
-
along a circular orbit
-
in an elliptical orbit
-
varying orbit depending on the comet
Comets revolve around the Sun in a highly elliptical orbit such that at one end of the orbit it is very far from the Sun and at the other end it is near to the Sun.

Meteorites are useful because:
-
those can be stored in the museum
-
those help the scientists in studying the material from which the solar system was formed
-
those cause destruction
-

What is a meteorite?
-
A meteor that reaches the surface of Earth
-
Shooting star
-
A constellation

Some meteors are large enough to reach the Earth's surface before they evaporate completely. Such meteors that reach the surface of Earth are called meteorites.
Identify the wrong statements for asteroids:
-
Revolve around the Sun
-
Separate inner and outer planets
-
Can only be seen through any telescopes
-
Asteroids are rock-like structures
Asteroids are rock-like structures that occupy the huge gap between the orbits of Mars and Jupiter.
All meteors reach the surface of the Earth. This statement is
-
True
-
False
Meteors that are small in size evaporate before they can reach the surface of Earth due to the heat generated because of friction between the meteor's surface and Earth's atmosphere. Only the bigger ones reach the surface of the Earth.
