when energy from the sun hits the air above land the air warms and rises land, the air warms up and rises. Along a coastline, cooler air above the ocean flows toward the land and replaces this rising air. Which best describes these processes.
Answers are in the between A1: conduction and convection , A2: conduction convection and radiation , A3: radiation and conduction , A4: radiation and convection
The processes described can be explained by a combination of conduction, convection, and radiation.
Conduction refers to the transfer of heat energy through direct contact between objects or substances. In this context, when the energy from the sun hits the air above the land, it warms up the air molecules through conduction.
Convection, on the other hand, involves the movement of heat energy within a fluid (such as air or water). As the air near the land's surface is warmed up by the sun's energy, it becomes less dense and starts to rise. This upward movement of warm air is known as convection.
Finally, radiation plays a role as well. Radiation is the transfer of energy through electromagnetic waves. When the sun's rays reach the Earth's surface, they provide radiant energy that heats up the air and land. The warming of the air and land is a result of the radiation absorbed by these objects.
Therefore, the best answer that encompasses all three processes is A2: conduction, convection, and radiation.
