TS 6th Class Science Important Questions 3rd Lesson Rain: Where Does it Come From?

I. Conceptual Understanding :

Question 1.
What are the three forms of the water ?
Answer:
Water on the earth can exist in 3 forms :
Ice (solid form), water (liquid form) and water vapour (gaseous form).

Question 2.
Define the following. Give suitable examples.
1) Evaporation
2) Condensation
(Or)
What is the process in which water changes to water vapour ?
Answer:
1) Evaporation: The process of changing of water into water vapour is called evaporation.
Eg : Cloud formation.

2) Condensation : The process of conversion of water vapour into water is called condensation.
Eg : Formation of rain.

Question 3.
What causes rain on the earth ?
Answer:
The cycle of evaporation and condensation of water, present on the earth’s surface, causes rain.

Question 4.
What is water cycle ?
Answer:
The conversion of water into water vapour, water vapour to clouds, clouds to rain is known as water cycle.

Question 5.
Write a few lines about the cause of floods or droughts.
Answer:

1. Deforestation and pollution from factories are now causing global warming.
2. So, the atmospheric conditions are not favourable for clouds to get cooled.
3. Consequently, there is a decrease in the rainfall. This leads to disturbance of water cycle and causes either floods or droughts.

Question 6.
Write the changes that take place in the following blank. Ice water ?
Answer:
Ice \(\rightleftharpoons\) water \(\rightleftharpoons\) ………………?
Ice \(\rightleftharpoons\) water \(\rightleftharpoons\) water vapour.

Question 7.
In our state rains occur normally from June to September. What is the name of this monsoon ?
Answer:

1. In our state rains occur normally from June to September.
2. During that season we observe in the sky that clouds move along with the winds blowing from western directions.
3. These winds are called “south – west monsoon”.

Question 8.
Explain north east monsoon and south east monsoon.
(Or)
What is meant by north – east monsoon ? In which season the rain occurs due to north east monsoon ?

1. Generally, we get rains in some particular months during the year.
2. In our state, rains occur normally from June to September .
3. During that season you might have observed in the sky that clouds are moving along with the winds blowing from western direction (south west side).
4. These winds are called “south west monsoon”.
5. Similarly, we observe in the months of November and December rains occur due to movements of clouds in the direction of winds blowing from eastern side (north – east side).
6. These winds are called “north – east monsoon”.

Question 9.
Explain various forms of water with suitable examples.
(Or)
In how many forms water exists on the earth ? How does water convert from one form to another ?
Answer:
Water is available in 3 forms

1. Solid
2. Liquid
3. Gaseous

1. Solid form of water:
Solid form of water is ice. The lowest temperature below 0°C converts water into ice.
Eg : Ice cubes in fridge

2. Liquid form of water:
When ice melts it will change into water, normal temperature converts the ice into liquid. :
Eg : Water in rivers, lakes, oceans

3. Gaseous form of water:
The gaseous form of water is water vapour which is present in the air around us.
Eg: Water vapour releasing from boiling vessel.

Question 10.
Describe the various stages of water cycle ? Explain what changes will occur in water cycle due to deforestation.
Answer:
Definition: The circulation of water into water vapour by evaporation, water vapour to clouds and clouds to rain by condensation is known as water cycle.

When it rains water bodies are filled with water. Some of this rain water seeps into the ground and becomes ground water. As it is very hot during summer, large quantity of water evaporates from water bodies and converts into water vapour.

This goes up into the air to form clouds. These clouds again cool and produce rain. Deforestation and pollution from factories cause global warming. Therefore atmospheric conditions become unfavourable for cooling of clouds. Consequently there will be decrease in rainfall. This disturbs the water cycle and causes either floods or droughts

Question 11.
Suppose you heard that there is raining in some area, but at the same time there may not be raining in other area. Why is it so ? (Conceptual Understanding)
Answer:

1. Often we see that there may be rain in some area, where it may not be in its adjacent areas.
2. This is because of condensation of clouds due to cool air which affects them in the specific area.
3. Occurrence of winds won’t be same in all the areas. Pressure influences the presence of air.
4. Clouds along with winds move from high pressure area to low pressure area at which cool air occurs.
5. That’s why rain is seen only in some areas, where we can’t see it in its adjacent areas.

Question 12.
If there is no evaporation and condensation (or) in the nature what would happen. What are the consequences of decrease in rainfall ?
Answer:
Absence of evaporation and condensation in the nature causes lack of rainfall. Consequences that occur due to lack of rains or less rain fall.

1. Fertile lands become unfit for harvestation.
2. Water scarcity occurs.
3. Rain based agriculture will face many problems. As a result, crops and plants will not grow.
4. Global warming will affect the earth.
5. Plants will die in every region.

Question 13.
What questions do you ask a meteorologist to know about clouds ?
Answer:

1. Why are clouds formed only in the sky ?
2. How are clouds formed ?
3. Why do we have rains only in some seasons ?
4. Why don’t we have rains in summer ?

Question 14.
In winter mornings we observe small dew drops on grass leaves. What is this process ?
Answer:
Especially during winter water vapour present in the air cools down due to cold weather. Therefore condensation occurs and as a result water vapour appears in the form of dew on the leaves.

Question 15.
Though it is rainy season, we are not getting enough rains. To find out the reason, what questions do you ask your teacher ?
Answer:

1. Why do not we have sufficient rains ?
2. What are the reasons for less rains ?
3. Who are responsible for having less rains ?
4. What should we do to have good rains ?

Question 16.
What changes are seen if there is no occurrence of condensation in the water cycle ?
(Or)
What happens if evaporated water does not condense ?
Answer:
If there is no occurrence of condensation in the water, water cycle stops due to lack of rains. If there are no rains water sources will not be filled with water. Even ground water level decreases. Low percentage of water levels in the natural water bodies cause damage to the living kingdom, thus it finally leads to destruction of nature. Hence condensation process is very essential in the water cycle.

Question 17.
“Clouds lead to falling of rains.” There are some other concepts like above in the lesson. Find out and write them.
Answer:
Some important concepts :

1. Three forms of water are interchangeable.
2. Evaporation is the process of water into water vapour.
3. Condensation is the process of water vapour into water.
4. The circulation of water in three forms in the nature is called water cycle.

Question 18.

(1) Evaporation
(2) Condensation
Answer:

1. Evaporation:
   • What is the importance of evaporation ?
   • How do we get clouds due to evaporation ?
   • Where do you find evaporation ?
2. Condensation :
   • Where do we see condensation ?
   • Define condensation.
   • What are the uses of condensation ?
   • What is the relation between rains and condensation ?

Question 19.
What happens if size of the evaporated water molecules increases in the cloud ?
Answer:
If size of the water molecules in the cloud increases, they convert into water droplets and condense to form rains.

III. Experimentation and field Investigation :

Question 20.
Explain the procedure to prove the conversion of water vapour into water.
(OR)
What is condensation ? How do you prove the process by condensation ?
Answer:
Definition : The process of conversion of water vapour into water is called condensation.

Procedure:

1. A vessel is taken and filled with water.
2. It is kept on a stove and heated slowly.
3. It is observed for sometime. Now the vessel is covered with a plate.
4. The plate is removed after a couple of minutes.

Question 21.
Explain the procedure to be followed in the experiment condensation.
(OR)
When we poured cool (water) drink in a glass, we observed water droplets on the outer surface of the glass. Why ?
Answer:

1. Ice cold water in the glass cools its surface.
2. Air around the glass contains water vapour which is warmer than the surface of the glass.
3. Due to the cold glass, air close to its surface will also become cooler.
4. This changes the water vapour in the air around the surface of the glass into water and forms small drops on the outer surface of glass. It occurs if there is only either ice or cold water.

Question 22.

3. Rain falling in one place is not seen in other place. Why ?
4. How does rain start in the sky ?

IV. Information Skills and Projects :

Question 23.
Read the information given below and answer the questions.
We call solid form of water ice. Snow occurs naturally. If we heat ice, it will change into water. Water in liquid form is present in oceans, seas, lakes, rivers and even underground. The gaseous form of water is water vapour which is present in the air around us. We know that when ice is heated, it converts into water and if water is heated it turns into water vapour. Similarly when water vapour is cooled we can get back water. If water is cooled further we get ice.

1. Name few sources of water in liquid form.
Answer:
Oceans, seas, rivers etc.

2. How do you interchange the three states of water ?
Answer:
Solid form of water (ice) is heated to convert into liquid state. Liquid form of water is further heated to convert into water vapour. Ice <— Water <— Water vapour

V. Communication through Drawing and Model Making :

Question 25.
In the given diagram you can observe droplets of water on the surface of ice containing glass.

1) Why are those drops formed ?
2) Do they form if there is no ice in the glass ?
Answer:

1. Ice cold water in the glass cools its surface.
2. Air around the glass contains water vapour which is warmer than the surface of the glass.
3. Due to the cold glass, air close to its surface will also become cooler.
4. This changes the water vapour in the air around the surface of the glass into water and forms small drops on the outer surface of glass. It will occur if there is only either ice or cold water. Draw the diagram of showing water cycle on the earth and label it.

Question 26.
Draw the diagram of showing water cycle on the earth and label it.
Answer:

Question 27.
Draw the diagram of water cycle and write a note on it.

Answer:
Definition : The circulation of water into water vapour by evaporation, water vapour to clouds and clouds to rain by condensation is known as water cycle.

When it rains water bodies are filled with water. Some of this rain water seeps into the ground and becomes ground water. As it is very hot during summer, large quantity of water evaporates from water bodies and converts into water vapour. This goes up into the air to form clouds. These clouds again cool and produce rain.

Question 11.
What will happen if there is no stomata in leaves? Write your predictions. (Asking questions and making hypothesis) 4 M
Answer:
If there is no stomata in leaves, the following things would happen.

1. Lack of stomata stops consumption of carbondioxide by leaves. As a result, photosynthesis stops.
2. Food stocks decrease in the plant. Finally the plant dies.
3. Absence of stomata in the leaves affects decrease in percentage of oxygen in the atmosphere, which is to be released by plants.
4. As a result, all the animals suffer a lot due to lack of oxygen. Finally, the animals die.
5. So, to regulate carbondioxide and oxygen, stomata are essential in the leaves.
6. Transpiration is another important property that is done through stomata to eliminate excess of water from plants.

TS 6th Class Science 16th Lesson Notes – Living and Non Living

• There are some movements in plants for example, closing and opening of flowers.
• By using carbon dioxide green colour substance in the leaves and sunlight, plants prepare their own food. This is called “photosynthesis”.
• When living things lose their life they become dead.
• Dead material decomposes to form non living things.
• Living things possess characteristics like growth, breathing air, excretion, movement, response to stimulate and giving birth to young ones.
• Among living things, plants and trees can’t move like animals.
• Seed is also a living thing but it doesn‘t have all characteristics of the living world.
• Living things : The things that possess the characteristics like growth, breathing, excretion, movement etc are called living things. Eg: Animals, birds, plants etc.
• Non – living things : The things that do not possess the characteristics like growth, breathing, excretion, movement etc are called non-living things. Eg: Rock, chair, table etc.
• Growth : The process of increasing physical size or development in a person, animal or plant is called growth.
• Breathing : The process of taking of air into the lungs and letting it out is called breathing. This is also a characteristic of living beings.
• Excretion : The process of getting rid of wastes is called excretion.
• Stimulus : Action that influences in or on the organisms.
• Movement : Living beings going from one place to another is called movement.
• Micro – organisms : A micro – organism is a very small living thing which we can only see through microscope.
  Eg: Bacteria, virus etc.
• Microscope : It is an instrument with the help of which we are able to see minute things that we can not see with our naked eyes. It works like mangifying lens but it is much more powerful.
