V. Answer the following in detail :
Question 1.
What are the different stages of water cycle?
Answer:
Stage I : Evaporation – The heat of the sun falls on the water bodies like Ocean, Sea, Lakes, Rivers, etc. The water slowly evaporates as vapours into the air.

Stage II: Condensation – As the vapours rise high, the cooler temperatures make them cool down and turn back into liquid. This is called condensation. Wind and air move the liquid around, leading to the formation of clouds.

Stage III: Precipitation – Wind movements cause the clouds particles to collide. They become rain-bearing clouds and fall back on to the earth’s surface by the process known as precipitation. This may occur in the form of rain, hail, snow, or sleet depending upon the temperature conditions.

Stage IV: Runoff and Infiltration – The water either runs off into oceans, rivers and ground surface or is absorbed into the soil (infiltration). This cycle continues.

Question 2.
Give few steps to save water.
Answer:

• Check your toilet for leaks.

Question 1.
உமது நண்பரிடம் உமக்குப் பிடித்த, பிடிக்காத பண்புகளைப் பற்றி வகுப்பறையில் கலந்துரையாடுக.
Answer:
மாணவன் 1 – : எனது நண்பன் கிருஷ்ணன். அவனிடம் எனக்குப் பிடித்தவை நிறைய குணங்கள் உள்ளன.
மாணவன் 2 : பிடிக்காதவையென்று ஏதேனும் உள்ளதா?
மாணவன் 1 : ஏன் இல்லை? பிடிக்காத அக்குணத்தை மாற்றிக் கொள்ளும்படி நான் கூறுகிறேன். அவன் சரி என்று கூறுவான். ஆனாலும் சில நேரங்களில் அவனைக் கட்டுப்படுத்த முடியவில்லை .

மாணவன் 2 : பிடிக்காத குணம் என்ன? பிடித்த குணங்கள் எவை?
மாணவன் 1 : பிடித்த குணங்கள் என்று ஒரு பெரிய பட்டியலே உள்ளது. அவை பிறர் மனம் புண்படாதபடிப் பேசுவான். யாரிடமும் சண்டை போட மாட்டான். தன்னைவிடச் சிறியவருக்கும் மரியாதை கொடுப்பான். பெற்றோர், ஆசிரியர் கூறும் வார்த்தைகளை மீறமாட்டான்.

மாணவன் 2 : இவ்வாறு இருந்தால் யாருக்குத்தான் பிடிக்காது?
மாணவன் 1 : சரியாகச் சொன்னாய்! அவனைப் பிடிக்காதவர் எவருமில்லை. ஆனால் தன்னை யாராவது ஏமாற்றுகிறார்கள் என்று தெரிந்தால் அவர்களிடம் பேசவே மாட்டான். கோபம் வந்தால் உச்சக்கட்டத்திற்குச் சென்றுவிடுவான். அவனை அடக்குவது எல்லோருக்கும் மிகவும் கடினமாக இருக்கும். அவன் அப்படி கோபம் கொள்வது எனக்கு பிடிக்காத ஒன்று.

மாணவன் 2 : பரவாயில்லையே, உன் நண்பனைப் பற்றி நன்றாகப் புரிந்து கொண்டுள்ளாயே?
மாணவன் 1 : குணம்நாடி குற்றமும் நாடி அவற்றுள் மிகைநாடி மிக்கக் கொளல் என்று வள்ளுவர் கூறியுள்ளார். அதன்படி என் நண்பனிடம் ஒரு சில பிடிக்காத குணங்கள் இருந்தாலும் பல நல்ல குணங்கள் அதாவது எனக்குப் பிடித்த குணங்கள் இருக்கின்றன.

பக்கத்து ஊருக்குச் செல்ல படகிலும் செல்லலாம், பேருந்திலும் செல்லலாம்… எதில் பயணம் செய்ய நீ விரும்புவாய், காரணம் என்ன?
Answer:
நான் படகில் பயணம் செய்ய விரும்புவேன்.
காரணம் :
சாலை வழிப் பயணம் என்பது எப்போதும் எளிதானது. வழக்கமாக நிகழும் ஒன்று. ஆனால் படகில் பயணம் செய்வது அரிதானது.
சாலையில் போக்குவரத்து நெரிசல் அதிகம். மேலும், மாசடைந்த காற்றைச் சுவாசித்துக் கொண்டே செல்ல வேண்டியுள்ளது.

படகில் பயணம் செய்யும்போது மிகவும் குளிர்ச்சியான சூழல் நிலவும். பயணம் செய்வதற்கான சோர்வு இல்லாமல் இருக்கும். இவையே நான் படகில் பயணம் செய்வதற்கான காரணங்கள் ஆகும்.
