A flag mounted on a flag post near the sea coast flutters in the direction of sea. At what time of the day does this happen — at mid-night or in the afternoon? [NCERT Exemplar]
Answers
Answer:
At night, the water cools down more slowly than the land. So, at mid-night, cool wind from the land moves towards the sea. Therefore, at mid-night the flag mounted on a flag post near the sea' coast flutters in the direction of sea.
Answer:
at midnight
Explanation:
due to land breeze, cold air moves towards sea
so that way Flag will point towards sea.
This process takes place for the duration of the night and the above-mentioned process gets reversed. Both, the land as well as the sea starts cooling down when the sun sets. As the heat capacity of land is different than the sea it cools down quicker. 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 the land breeze
this is called land breeze
