Explain the importance of convection currents in blowing coastel breeze and bird's gliding in the air.
Answers
Answer:Convection currents also take place in the atmosphere. The heat from the Sun warms the air near the ground. The warm air expands and becomes lighter in weight. During gliding flight, a bird does not move its wings but glides on air currents
Answer:
Sea breeze
Sea breezeOn a sunny day the land heats up more quickly than the sea because land absorbs heat faster than water. Hence, air over the land surface becomes more heated than air above the sea. So the hot air over the land being lighter moves up and the cooler air from the sea takes its place. Thus a cool and comforting breeze blows from the sea to the land. Therefore, it is called sea breeze.

Therefore, it is called sea breeze.Land breezeThe situation during the night is opposite. The sun is not there to heat and the cooling process has started. The land gives up heat more quickly than water. Thus, the air above the sea remains warmer and moves up while its place is filled up by the cool breeze blowing from the land. Therefore, this breeze from land to sea is called the land breeze.
