Question

Few flags were unfurled on the ships in an ocean.It is observed that the flags were fluttering in the direction of the sea. This occurs at midnight or in the afternoon?

Answer 1

• This process takes place during the night.
• The land and the sea start cooling down when the sun sets.
• Land loses heat faster than water and thus, it cools down quicker. This leads to cooler air above the land and warmer air above the sea.
• Thus, a low-pressure situation develops over the sea as the temperature above it is higher when compared to the land.
• Due to this, the air flows from the land to the sea which is termed as the land breeze.
• In the question, flags were fluttering in the direction of the sea which means wind is blowing from the land towards sea.
• It is possible only in the case of land breeze which occours at night.
