Single correct option
A sea breeze blows from the sea towards the land during the day mainly because
- A. water has lower specific heat capacity than land
- B. land has lower specific heat capacity and heats up faster than water
- C. the sea is hotter than the land in the day
- D. air above the sea is lighter than air above the land
Show answer and solution
Answer: (B) land has lower specific heat capacity and heats up faster than water
Land has a smaller specific heat capacity, so it warms faster in sunshine. Air above it becomes hot and rises, and cooler air from the sea moves in to take its place. At night the land cools faster and the direction reverses, giving a land breeze.
