12th Class English Chapter 1 The Dying Sun Short Question Answer
1.How is it that a star seldom finds another star near it?
Innumerable stars move in space. They travel alone. They are far away from each other. So a star cannot come near the other.
2.What happened when according to sir James jeans a wandering star wandering through space came near the sun? 3.What happened when the wandering star came nearer and nearer? 4.What are planets and how did they come into existence?
(of Q.2.3.4) A wandering star came near the sun. It raised a big wave on the surface of the sun. The nearer the star came the higher the wave rose. Then the wave broke into pieces. These pieces fell off the sun. They began to move round the sun. They came to be known as planets. Our earth is one of them.
5.Why is there no life on the stars?
The stars are the big burning balls of fire. Life would melt away there. Therefore there is no life on the stars.
6.Write a note on the beginning of life on earth?
Sir James jeans says that life began in the form of a living organism. Then it changed into a human being. In this way life began on earth.
7.Why is the universe of which our earth is a part so frightening? Give as many reasons as you can?
The universe is full of burning stars. The space is very cold. Life cannot exist anywhere except on earth. All these things make the universe frightening.
8.What in your opinion should be the conditions necessary for the kind of life we know to exist on other heavenly bodies? Do such conditions generally exist?
Air water and moderate temperature are necessary for life. These things do not exist anywhere in the universe except on earth.
9.How big are the stars? OR Can a star contain millions and millions of earths in it?
A few stars are hardly bigger than the earth. But most of the stars are so large that hundreds of thousands of earths could be packed inside each. Some stars can contain millions and millions of earths in them.
10.How much chance is there for a star to come near the other? OR What would be the rare event according to Sir James jeans? OR Can a star come close to the other? OR Why can teo stars not come close to each other?
According to Sir James jeans it would be a very rare event indeed if a star comes anywhere near the other. It is so because the empty space between them is unimaginably vast.
11.What rare event took place some two thousand million years ago? OR When did a star happen to come near our sun?
Some toe thousand million years ago a star happened to come near our sun.
12.What happened to the sun when a star came near it? OR Why/How were the tides raised on the surface of the sun?
When a star came near our sun it raised huge tides on the surface of the sun. It happened so because of the gravitational pull of the new star.
13.What was the result when the new star came nearer to the sun? OR What happened when to new star came nearer to the sun?
The nearer the star came the higher the mountain of tides rose on the surface of sun. It happened so because of the increasing pull of the new star.
14.Whar are the planets and what are they doing? OR Since how much time have the planets been revolving/moving round the sun? OR What is revolving round the sun?
The small pieces of matter that fell off from the surface of sun are known as planets and they have been moving round the sun since then. Our earth is also one of them.
15.How much hot are the stars?
The sun and other stars that we see in the sky are extremely hot. They are the big blazing balls of fire. Life cannot exist there. IT would be burnt to death.
16.How when and why did life come into existence?
Sir James jeans admits that no body knows hoe when and why life came into existence. It just came into being somehow or the other.
17.How did life develop/grow with the passage of time? OR What happened to life with the passage of time?
With the passage of time it grew form mono-celled to multi-celled organism. It became more and more complex.

19.What is the fear of humans when they try to probe into the universe? OR why is the universe frightening to us? OR Why do humans feel frightened of the universe? OR Do we find life elsewhere in the universe?
The universe is frightening to us because of its wide distances and long stretches of time. We feel lonely on our little earth because there are no signs of life elsewhere in the universe.
20.Does life seem to be a part of the plan which produced our planetary system?
No, According to Sir James jeans life does not seem to have any part in the plan which produced our planetary system.
21.What conditions are necessary for life to exist? OR Where/When is life possible to exist?
Life can exist on a planet like earth. It needs certain suitable conditions for its existence. The most important condition for life is moderate temperature at which substance can exist in a liquid state.
22.Define the life zone or life belt in the universe?
Life can exist in a narrow belt at a certain distance from the stares where temperature is neither too hot nor too cold.
23.What are temperature belts?
These are the temperature zones at certain distances from a star. The space near the stars is comparatively hotter than the belts away from them.
24.What is a planetary system?
When a star throws off its pieces they begin to move round it. These pieces are called its planets. Their relative arrangement and distances from each other and from the star is called a planetary system.
25.What is the difference between stars and planets?
The stars are the big burning balls of fire. They never lose their heat. They wander alone in space. When a star throws off its pieces they begin to move round it. There pieces are called its planets. With the passage of time they lose their heat and cool down.
