Question 1 - True or False - Chapter 4 Class 9 Geography - Climate - Geography

Which of the following statement is false?

A. Cyclonic disturbances from the west and northwest bring winter rains and snowfall over northern plains and are important for 'rabi' crop cultivation in North India.

B. Climate is described as the long-term pattern of weather. 

C. The Coriolis force deflects winds towards the right in the Eastern Hemisphere and towards the left in the Southern Hemisphere. 

D. Houses in Rajasthan have thick walls and flat roofs.

Answer:

So, the correct option is (C): The Coriolis force deflects winds towards the right in the Eastern Hemisphere and towards the left in the Southern Hemisphere. 

Explanation 

Let’s check all the options 

• (A) Cyclonic disturbances from the west and northwest bring winter rains and snowfall over northern plains and are important for 'rabi' crop cultivation in North India . This is true because these low-pressure systems form over the Mediterranean Sea and western Asia before moving into India with the westerly flow. They bring much-needed winter rains to the plains and snow to the mountains , known locally as'mahawat and is suitable for the cultivation of 'rabi' crops.
  
  
• (B)Climate is described as the long-term pattern of weather . This is true because Weather conditions and variations over a large area stay for a long period of time
  
• (C)The Coriolis force deflects winds towards the right in the Eastern Hemisphere and towards the left in the Southern Hemisphere . This is false.
  Correct Statement: The Coriolis force deflects winds toward the right in the northern hemisphere and toward the left in the southern hemisphere.
  
  
• (D) Houses in Rajasthan have thick walls and flat roofs. This is true because the climate of Rajasthan is extremely hot. So, these thick walls protect the heat from entering the house and keep the house cool.
