CHAPTER 2A-RAIN AND RIVERS (PART 1) 1.3 Improve Your Learning Conceptual Understanding Q1. Where does evaporation and cloud formation take place on a large scale? [Refer to TB page 21 Q1] A. Maximum evaporation and cloud formation takes place on the surface of the oceans i. Clouds are tiny droplets of water hanging in the air above. ii. Clouds are generally formed in the sky. iii. Clouds are being formed all over. Q2. Explain how water changes into water vapour and also how clouds are formed from water vapour? [Refer to TB page 21 Q1] A. i. Water vapour in the air comes mainly through evaporation from lakes, ponds, seas and other water bodies. ii. When water changes into gaseous state the process is known as evaporation. iii. Evaporation occurs at all times and in all places. iv. Water vapour present in the air varies from place to place. v. When water vapour rises with hot air and reaches high up in the sky, it gets cooled. vi. With the cooling, water vapour is transformed into tiny water droplets. vii. These droplets gather around minute dust or smoke particles in the air and gradually increase in size. viii. These small drops of water gather to form clouds. ix. If they get heavier it gets more difﬁcult to remain in the air and fall down as rain drops . 1.4 Key Concepts i. Over 70% of the earth’s surface is covered with water. ii. After the hot summer of April, May and June comes the rainy season. iii. Water which evaporates becomes vapour and later it condenses into water after being cooled. iv. When water is not boiling there is still evaporation. v. Change of water into vapour is known as evaporation. vi. The process in which water vapour changes into water is called condensation. vii. The amount of invisible water vapour present in the atmosphere is known as humidity. viii. Oceans are the vast water bodies extending up to thousands of kilometers. ix. There are various water bodies like ponds, rivers, lakes, seas and oceans on the surface of the earth. SESSION 1. HOW DOES RAIN OCCUR 12

[Refer to TB page 21 Q4] a) Sea coasts that are in the direction of the winds b) Mountains that are in the direction of the winds c) Lands far away from the seas. A. (b) mountains that are in the direction of winds. Q3. Describe the main stages of the water cycle. [Refer to TB page 21 Q7] A. The main stages of water cycle are: i. Evaporation: Due to the heat of the sun water evaporates from the water bodies like oceans, seas, rivers etc. ii. Formation of clouds: When this water goes up it forms clouds. iii. Raining: As the clouds condense the water drops formed fall to the earth as rain. iv. Reaching the water sources: Through streams and rivers the rain water again reaches the water sources. Again the evaporation takes places. Q4. Fill in the blanks choosing the correct options (bank, tributaries, ﬂood–plain, river valley): [ Refer to TB Page 21 Q.5] i. A river ﬂows through the . ii. Streams or rivers joining a larger river are called the of the main river. iii. The entire valley, of a river which is ﬁlled with water during the ﬂoods is called the of the river. A. i. A river ﬂows through the River valley. ii. Streams or rivers joining a larger river are called the tributaries of the main river . iii.

CHAPTER 2B-RAIN AND RIVERS (PART 2) Q5. The Godavari ﬂows from the west to the east. Why? [ Refer to TB Page 21 Q.6] A. Because the slope of Andhra Pradesh is from west to east. We know that the river ﬂows in the same direction as that of the slope, so Godavari ﬂows from west to east. 1.4 Key Concepts i. Rain causes small streams along the mountains, over their slopes. ii. The rivers are the cause for formation of plains. iii. Towards the end of its journey to the sea, a river forms a delta. iv. If the surface of the land is covered with vegetation then soil erosion is greatly reduced. v. Rivers or streams which join a larger river are called tributaries. vi. The south–west monsoon sets around June and it brings most of the rainfall to Telangana, Rayalaseema and coastal areas. vii. The retreating or North–East Monsoon sets after october and brings a little rain to Rayalaseema and Telangana districts and more to Coastal Andhra. SESSION 1. RIVERS 17
