1. When the water vapour present in the condenses and falls on the ground it is called rain. 

     When the temperature falls down below freezing point water turns into snow.

2. Wind is air that moves quickly.

   Pressure is force per unit area.

3. Whether-the condition of the atmosphere at a particular place and time.

   Climate-weather condition of a particular place.

4. Torrid zone refers to the area near the equator.

      Frigid zone refers to the area near the poles.

5. Permanent adaptation causes permanent changes in the living beings.

     Temporary adaptation is a short time adaptation.

C. Give one word answer for each of the following:-

1. Climate 2.anemometer 3. altitude 4. North pole.

D. Match column A with column B:-

1. Wind direction 2. imaginary lines 3. polar bear 4. long beak.

E. Give two examples for each of the following:-

1.Humidity, temperature 2. temperate zone, tropical zone 3. industry,fall of tree 4. the cow, the deer.

F. Give reason for each of the following:-

1. During summer air gates warm, it gives higher up causes vacuum. This cause loo blow in summer.

2. Climate become colder in higher altitudes because with altitudes temperature decreases.

3. Deforestation and industrialization cause lesser rainfall.

4. High long legs of camel help them back in hi sand. Food remain store in the humps of camel.

5. Trunks of elephant help to eat. To carry  log. To take bath.

G. Write true or false:-

1. False 2. false 3. false 4. true 5. false

I. Fill in the blanks:-

1. Hygrometer 2. raingauge 3. temperate 4. elements 5. heat.

J. Short answer question:-

1. Weather-condition of the atmosphere at a particular place and time.

2. Factors are-

(a). Altitude

(b). Distance from sea.

3. Using maximum and minimum temperature.

4. The average weather of a place over a long time is called the climate of that place.

5. Because they have thick layer of fat below their skin.

6. Giraffe, elephant and horse.

K. Long answer question:-

1. Humidity is the amount of water present in the atmosphere. Humidity is the measure of dampness in the air. A dryer place will have lower humidity whereas places near the sea coast will have higher humidity. The humidity is measured using a hygrometer. When air contains 100% of most the air is said to be saturated. In India during the time of monsoon the humidity is higher. Humidity where is with the change in temperature.

2. The factors that determine the climate of a place are as follows-

(a). Distance from equator-the place the equator are hot while those away from equator are cold.

(b). Altitude is height above sea level- the places at higher altitudes have cold climates.

(c). High mountains-high mountain block moisture-laden air causes rain.

(d). Distance from sea.

(e). Winds.

3. Elements of weather are- 

1. Temperature 2. Humidity 3. Rainfall or snowfall 4. Wind speed 5. Pressure.

Factor affect climate are-

1. Distance from equator 2. Altitude is height above sea level 3. High mountains 4. Distance from sea 5. Winds.

4. Adaptations in Elephants- 

1. It has a big trunk used as a nose and picking up food.

2. Its trunk can tear the bark of trees.

3. It has large ears to audio small sound.

5. Camouflage is the way in which an animals colour or safe matches its surroundings and makes it difficult to see. e.g. Adaptation in camels-

1. It has a brown colour body which matches well  with the surroundings.

2. It has long eyelashes which protect the eyes during high speed of wind.

3. It can close its nostril to prevent send from entering the nasal cavity.

4. The animal can drink over 40 lts of water at a time and this water is store for later use.
