1. How is heat transferred by convection? Explain whiith the help of a diagram.
2. How are sea and land breezes formed?​

Answer 1

Answer:

1)Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid

2)The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

Answer 2

Answer:

Land and Sea breezes are basically caused by differential heating between land and sea.

During the day, 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. So the pressure over water is low and high on land. So we have a land breeze blowing from land to sea.
