The term 'monsoon' denotes the seasonal change in wind direction that occurs during which specific time period?

Correct option is D

The term monsoon refers to a seasonal change in wind direction that typically occurs on an annual basis. Monsoons bring about significant changes in climate, characterized by wet and dry seasons, and are driven by the shifting of wind patterns over large geographic regions. These wind changes generally occur at the beginning of the summer and winter seasons, marking distinct rainy and dry periods.

Key points:

• The monsoon occurs annually, with specific wind patterns shifting from one direction to another based on the Earth's tilt and seasonal temperatures.
• The Indian subcontinent, for example, experiences the southwest monsoon during the summer months (June to September) and the northeast monsoon during the winter months (October to December).

Additional Information:

• The Southwest Monsoon is a prominent feature of the Indian subcontinent and is vital for the agriculture-dependent regions. It begins around June and lasts until September.
• The Northeast Monsoon brings rain to southeastern regions like Tamil Nadu and Andhra Pradesh during the winter months.

Other Options:

• Two decades: This period is far too long for monsoon changes, as monsoons occur seasonally, not over decades.
• Two months: Although the onset and retreat of the monsoon can be observed over a few months, the monsoon itself refers to an annual cycle, not just a two-month period.
• One day: Monsoon changes are not confined to a single day; they unfold over a seasonal cycle, usually across a few months each year.
