Single correct option
A sea breeze blows from the sea towards the land during the day because
- A. water heats up faster than land, so air above the sea rises
- B. land has a higher specific heat capacity than water
- C. land heats up faster than water, so air above it rises and cooler air from the sea moves in
- D. the air over the sea is denser due to salt in water
Show answer and solution
Answer: (C) land heats up faster than water, so air above it rises and cooler air from the sea moves in
Water has a high specific heat capacity, so it warms slowly, whereas land warms rapidly. The warm air over land rises, creating a low-pressure area, and cooler air from the sea flows in to replace it. At night the situation reverses and a land breeze blows. Land has the lower, not the higher, specific heat.
