cont. Applications of convection in real life

Sea and Land Breeze

Another example of the works of convection in real life will be the forming of land and sea breeze.

1. Sea Breeze
-In the morning where the sun is up high and scorching hot, the land will heat up faster than the sea(water)
-The air above the hot/heated land will be heated and hot air rises.
-As a result, the hot air from the land rises while the cool air above the sea rushes towards the land, forming the sea breeze in the day.
-Sea breeze blows from the sea to the land.

2. Land Breeze
-As for the land breeze, it only forms during the night where the land is cooler than the sea.
-The land cools faster than the sea and thus the cool air above the land moves towards the sea.
-While the warm air above the sea rises.
-Land breeze is form and the breeze blows from the land to the sea.

As seen in the picture below, the formation of sea and land breeze is by convection.
Hot air rises and cold air sinks.
