6. Land and sea breezes are also the examples of convection. conduction . It is called sea breeze. Convection: Transfer of heat by actual movement of molecules from hot place to a cold place is known as convection. At night, breeze blows from the land towards the sea. Sea breeze - daytime. Figure A. B. are caused by currents set up in air due to convection. Once again, the bigger the difference in temperature between the two, the stronger the wind. all of these . Click hereto get an answer to your question ️ Sea breeze and land breeze. Sea breeze - nighttime. a) Fourier’s law Air currents help them to … convection . ... Land breeze - daytime. Tags: ... Conduction Convection Radiation . 4.6k plays . Convective heat transfer is caused by molecular motion in fluids. (Adapted from graphic by NOAA). Question 8: Heat is a form of . Only this time it is known as the land breeze. energy. When the molecules are heated, their temperature increases and they tend to move away from each other. Heat and Changes of Matter . Which of these does not require a medium–conduction, convection or radiation? What conditions would no sea breezes occur? convection. Land breeze - nighttime. The Coriolis Effect causes the wind to move in a clockwise motion. Sea breeze is caused due to . For transmission of heat through convection, actual movement of particles of that medium is essential. This process also works in reverse at night. The flow of breeze from the sea to the land or from the land to the see occurs due to the process of convection. Sea Breeze (Left) and Land Breeze (Right). Solution : Because land absorbs solar radiation far more quickly than water, a sea breeze is a common occurrence along coasts after sunrise. At certain locations, converging sea breezes can cause thunderstorms during the afternoon. Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock (rheid). Correct Option is : 2. Q.19. Ans: Radiation does not require any medium. 2.4k plays . Convection is one of the three modes of heat transfer; radiation and conduction being the other two. radiation . 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. Other . Through the process of radiation, the heat can be transferred even in the vacuum. Early sailors used the winds to navigate the oceans. ... physics. Correct Option is : 2. Q.18. A. are caused by currents set up in air due to conduction. wave. The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. radiation. 5. Radiation in this context is referring to IR (infrared radiation) which is emitted from hot objects and travels out in all directions at the speed of light and can travel through a vacuum. It causes land and sea breeze in coastal areas. Solution : d) The formation of sea and land breeze Answer: d Clarification: The formation of sea and land breeze is an example of convection. C. are caused by currents set up in air due to radiation. The other examples are due to conduction where transfer of heat in internal energy by minute collision of particles and electron movement within a body. Which law governs the thermal conductivity? Conduction is caused by vibrations of particles largely in solids, especially metals which conduct heat well. Applications of Convection. Gliders use upward movement of hot air currents due to convection of heat. 18 Qs . Sea breeze and land breeze. In coastal areas, breeze blows from the sea towards the land during the day. This is why you feel heat from the sun on earth. A hurricane is an independent, self-sustaining storm system not related to the regional convection that causes land and sea breezes. Sea and land breezes: a) are caused by currents set up in air due to conduction b) are caused by currents set up in air due to convection c) are caused by currents set up in air due to radiation d) have no relation to conduction, convection, or radiation 6. Convection is the movement of molecules within fluids (liquids or gases). Convection causes land and sea breezes to occur.
