Solution

  1. (c) Basin Explanation: Tributaries are small rivers that join the main river. The main river along with all its tributaries that drain an area form a river basin or the catchment area. The Amazon Basin is the largest river basin in the world.The place where a river flows into another body of water is called the river’s mouth.
  2. (d) Spanish Explanation: Spanish
  3. (c) Silk Explanation: In the Ganga-Brahmaputra basin. The soil is fertile. Agriculture is the main occupation of the people where flat land is available to grow crops. The density of population of the plains is very high. The main crop is paddy. Wheat, maize, sorghum, gram and millets are the other crops that are grown. Cash crops like sugarcane and jute are also grown. Banana plantations are seen in some areas of the plain. Silk is produced through the cultivation of silk worms in parts of Bihar and Assam.
  4. (a) People plant more and more tree Explanation: Planting trees is one of the remedy 
  5. (d) Rice and fish Explanation: Rice and fish

  6. (a) - (iii), (b) - (i), (c) - (iv), (d) - (ii)

  7. Slash and burn agriculture

  8. False

  9. The Amazon Basin stretches directly on the equator and is characterized by a hot and wet climate throughout the year.

  10. Amazon forest is shade tolerant. Hence, it is called evergreen.

  11. The basin area has varied topography. As a result, the distribution of population is not even everywhere in the area. The mountain areas with steep slopes have inhospitable terrain. Therefore less number of people live in the mountain area of the Ganga Brahmaputra basin. The plain area provides the most suitable land for human habitation. Therefore, the density of population of the plains is very high.

    1. People grow food after clearing some trees in the forest. Men hunt and fish along the river, while women take care of the crops.
    2. The main crops are tapioca, pineapple, and sweet potato. Slash and burn cultivation is practiced and the staple food is manioc.
    3. They eat queen ants and egg sacs. Cash crops like coffee, maize, and cocoa are also grown.

  13. The people of the Amazon basin practise slash and bum agriculture. They grow most of their food in small areas after clearing some trees in the forest. Men hunt and fish along the rivers and women take care of the crops. They mainly grow tapioca, pineapple and sweet potato. As hunting and fishing are uncertain it is the women who support the family. They feed them the vegetables that they grow. Their staple food is manioc, also known as cassava that grows under the ground like potato. They also eat queen ants and egg sacs. Cash crops like coffee, maize and cocoa are also grown. People get wood for their houses from the rainforests. They build thatched houses shaped like beehives. There are also malocas which are large apartment-like houses with a steeply slanting roof. The Amazon basin is developing day by day. In 1970 the trans-Amazon Highway made all parts of the rainforest accessible. With the change of time, the people's lifestyle is also changing gradually.
