Question 55

Give reasons:

(a) Rituja frequently travels between Bengaluru and Chennai and notices that the number of wet days is higher in Chennai than in Bengaluru.

(b) The number of tropical cyclones experienced in the Bay of Bengal is more than in the Arabian Sea.

Answer

(a) Chennai is located on the Coromandel Coast (Tamil Nadu) and receives most rainfall from the Northeast Monsoon and the Retreating Monsoon. Bengaluru, located inland in Karnataka, primarily receives rainfall from the Southwest Monsoon. Hence, Chennai has more wet days than Bengaluru.

(b) Tropical cyclones are more common in the Bay of Bengal than in the Arabian Sea because the Bay of Bengal is surrounded by land that traps heat. Due to this, the Bay of Bengal has warmer sea surface temperatures, which provide more moisture and energy for cyclone formation.
