Web19 feb. 2024 · That heat transferred to the troposphere via convection and latent heat later gets transported elsewhere via convection (downdrafts), rain, and radiation. That elsewhere can be higher up into the atmosphere (and eventually into space) or back to the surface (which is important with regard to the workings of greenhouse gases). $\endgroup$ WebList and describe each process. *ANSWER----. Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. on the standby https://steveneufeld.com
