What causes land breeze and sea breeze?
A) The differential heating of land and sea by the Sun results in the movement of air.
B) Hot air from the sea blows over the land because there is a high pressure area over the sea.
C) Cold air blows from the land over the sea because there is a low pressure area over land.
D) Air blows from land over the sea because of the rotation of Earth on its axis.
I think the answer is A or B but I m leaning toward B.
The correct answer is A) The differential heating of land and sea by the Sun results in the movement of air.
During the day, the land heats up faster than the sea due to its lower specific heat capacity. This leads to the air above the land becoming warmer and less dense, causing it to rise. As a result, a low-pressure area forms over the land.
At night, the land cools more rapidly than the sea because it loses heat faster. This causes the air above the land to become cooler and denser, leading to a high-pressure area. The high-pressure air then moves from land to sea, resulting in a land breeze.
In contrast, during the day, the air above the sea remains cooler due to its higher heat capacity. This causes high pressure to form over the sea. The cool air then moves from the sea to the land, resulting in a sea breeze.
Therefore, it is the differential heating of land and sea by the Sun that causes the land breeze and sea breeze phenomenon.
The correct answer is A) The differential heating of land and sea by the Sun results in the movement of air.
To explain how this happens, during the day, land heats up faster than the sea because land has a lower heat capacity. This causes the air above the land to warm up and rise, creating a low-pressure area. At the same time, the sea remains relatively cooler, resulting in high pressure over the water.
Air moves from areas of high pressure to low pressure, so the air over the sea flows towards the land, creating a sea breeze. This breeze is typically cooler than the surrounding land due to the sea's lower temperatures.
At night, the situation reverses. The land cools down more rapidly than the sea, causing the air to cool and sink, creating high pressure. The sea, which retains heat for a longer period, remains warmer, resulting in low pressure over the water.
As a result, the air flows from the land towards the sea, creating a land breeze. Land breezes are typically cooler than sea breezes because the land loses heat quickly.
Therefore, the primary cause of both land and sea breezes is the differential heating of land and sea by the Sun.
It is B.
The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
