Question

Which of the following factors is the cause of sea breeze?

• A. Convection currents
• B. Rains
• C. Conduction
• D. Cyclones

Answer 1

The correct option is A Convection currents

Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. Sea breeze occurs during the day. The sun heats up both sea surface and land. As the sea has a greater heating capacity, it absorbs much of the sun’s energy but gets warmed up much slower than the land. As a result, the temperature above the land rises and heats the air in the atmosphere above it. Warm air is less dense and hence, it expands, creating a low-pressure area over the land near the coast. Meanwhile, there is a relatively high pressure over the sea. The difference in air pressure causes the air to flow from sea to land. The sudden gush of wind felt due to this is known as the sea breeze.
