Weather, Climate and Adaptations of Animals to Climate (Part - 1)

 Weather, Climate and Adaptations of Animals to Climate

Q.1. Which department of the Government prepares the weather reports.

Ans. The weather reports are prepared by the Meteorological Department of the Government. This department collects data on temperature, wind, etc., and makes the weather prediction.

Q.2. Differentiate between weather and climate.

Ans. 

Weather

Climate

It is the day to day condition of the atmosphere at a place at a particular time.

It is the average weather pattern taken over a long period of time.

It can vary over very short periods of time.

It does not vary in short periods.

 

It cannot force adaptations in the organisms.

It forces adaptations in the organisms.

 


Q.3. Define:

a) Weather

b)Humidity

Ans. a) It is the day to day condition of the atmosphere at a place at a particular time.

        b) Humidity is the concentration of water vapor present in the air.

Q.4. a) Name the instrument which measures rainfall.

        b) What causes all changes in the weather?

Ans. a) The instrument which measures rainfall is rain gauge. It is basically a measuring cylinder with a funnel on top to collect rainwater.

    b) All changes in the weather are caused by the heat energy of the sun absorbed and reflected by the earth’s surface, oceans and the atmosphere.

Q.5. At what time of the day/night the temperature at any place is :

A) Maximum?

B) Minimum?

Name the instrument used for recording maximum & minimum temperature of the day.

Ans. The maximum temperature of the day occurs generally in the afternoon while the minimum temperature occurs generally in the early morning.

There are special thermometers for this purpose, called maximum and minimum thermometers.

Q.6. Mention the various factors that affect the weather at a particular region? On the  other hand, what are the factors that affect the climate of a region?

Ans. The day- to-day condition of the atmosphere at a place with respect to the temperature, humidity, rainfall, wind- speed, etc affect the weather at a particular region.

There are six major controls of the climate of any place. They are: latitude, altitude, pressure and wind system, distance from the sea (continentality), ocean currents and relief features.

Q.7.Differentiate between the climate of Kerala and Rajasthan.

Ans. The climate of Kerala is very hot and wet as Kerala have coastal regions while the climate of  Rajasthan is hot and dry as Rajasthan is a desert area and do not get much rainfall.

Q.8. The climate of the north-east is:

a) Wet

b) Hot and dry

c) Hot and humid

d) Cold

Ans. a) Wet

Q.9. The maximum and minimum temperatures are recorded:

a) Every month

b) Every year

c) Every day

d) Every week

Ans. c) Every day

Friction (part-1)

FRICTION Q.1. What is force? Write few of its characteristics. Ans.1.  A push or a pull on an object is called a force.                      Force is a vector quantity (having magnitude  as well as direction).           S.I. unit of Force is N (Newton).           Force can Change the State of Motion.                   Force can Change the Shape of an Object. s          Q.2. What is friction ?      Ans.2.  The force which opposes the motion of an object on the surface of another object is called force of friction. Force of friction is a contact force. The force of friction always opposes the applied force (direction of motion).

Sound (part -1) class 8

SOUND Q.1. What is sound? Ans. Sound is a form of energy, a sensation felt by our ears and makes us able to hear something. We hear many sounds around us like: sounds of talking, chirping of birds, ringing of bell, fluttering of clothes, machines etc. Q.2. What is the cause of sound? Ans. Vibration in an object produces sound. To and fro or back and forth motion of an object is called vibration. The energy required to make an object vibrate and produce sound is provided by some outside sources (like our hands, wind etc.). For example: We can feel vibrations by keeping our hand on our throat while speaking where vocal cords vibrate to produce sound. The sound of a ‘Dholak or tabla’ is produced by the vibrations of its stretched membrane on strucking. Q.3. Tabulate the Musical Instruments and their Vibrating Parts which vibrate to produce sound. Ans. S.No. Vibrating Part of Instrument Producing Sound Examples 1. Stretc...

Friction (part-2)

FRICTION Q.3.  Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it. Ans.3.                                 Q.4. What is the cause of friction? Ans.4.  Friction occurs due to the interlocking of irregularities between two surfaces in motion to each other. Every object has some sort of irregularities in its surface, so when two surfaces come in contact with each other and one object moves over the another, so their irregularities get interlocked and moving object starts losing its energy in breaking the interlocking and finally it comes to rest.                                             Q.5. What are the factors on which friction depends? Ans.5.  There are two factors affecti...
