SHORT ANSWER TYPE QUESTIONS
1. Write a short note on the climate of the Amazon Basin.
Answer: The climate of the Amazon Basin is characterised by hot and wet climate throughout the year. Both day and night and almost equally hot and humid. It rains almost everyday. The day temperatures are high with very high humidity. At night the temperature goes down but the humidity remains high.
2. What do you know about the location of the Ganga-Brahmaputra Basin? Mention the climate of this Basin.
Answer: The Ganga-Brahmaputra Basin lies in the sub-tropical region that is situated between 10°N to 30°N latitudes. The tributaries of river Ganga such as the Ghaghra, the son, the Chambal, the Gandak, the Kosi and the tributaries of Brahmaputra drain it.
The area of the Ganga-Brahmaputra Basin is dominated by the monsoon climate. The monsoon brings rains from mid-June to mid-September. The summers are hot and the winters are cool.
3. The Ganga-Brahmaputra Basin has varied topography. How does it affect the distribution of population there? [V. Imp.]
Answer: The basin area has a varied topography. As a result, the distribution of the 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 the population of the plains is very high.
