GEOLOGY

Detailed explanation-1: -[more on electromagnetic radiation] It is infrared radiation that produce the warm feeling on our bodies.

Detailed explanation-2: -When you first lie down on hot sand, then the energy flows from the hot sand to your cooler body by conduction. Free or natural convection is heat transfer carried by a rising current of fluid due to buoyancy effects created by the hotter fluid being less dense.

Detailed explanation-3: -Types of Heat Transfer: 1.) Radiation: The sun’s thermal energy is warming the beach, this is indicated by people wearing bathing suits and swimming in the water.

Detailed explanation-4: -Radiation heats a person directly, and indirectly both conduction and convection play a role in the heat felt by the person.

Detailed explanation-5: -Breeze. The formation of sea and land breeze form the classic examples of convection. Going by the definition of convection, the molecules at a higher temperature displace the ones at a lower temperature. Similarly, in the afternoon, the surface of the land near the sea is warmer as compared to in the evening.
