Question

explain land and see breezes and show how they are examples of convection currents in nature. support your answer with diagram​

Answer 1

Answer:

There are 3 ways that heat travels: conduction, convection, and radiation. Convection happens in fluids. What happens is that as a fluid heats up, it expands. Since it has expanded, it is less dense than the fluid next to it, so it rises above it. In the atmosphere, with sea and land breezes, as either the ground or sea is warmer than the other, it heats the air above it. This air rises above the cooler air next to it. The cooler air then moves in to take the place of the warmer air that just rose up. This air then is warmed by the ground or water beneath it, so it then rises, and so on.The warmer air that has risen moves up where the air pressure is lower, so it expands. As this happens it cools down. Now it’s cooler than the other air up high, so it sinks down. This warming -> rising -> cooling -> sinking sets up the convection current.

Hope this helps you

In the atmosphere, with sea and land breezes, as either the ground or sea is warmer than the other, it heats the air above it. ... Now it's cooler than the other air up high, so it sinks down. This warming -> rising -> cooling -> sinking sets up the convection current.
