___________________________________________________________________________________________________Construct an engaging 2-paragraph initial post focused on one of the main processes important atmospheric energy transfer – conduction, convection, radiation, or latent heat of water. The paragraphs should address the following points:
- Paragraph 1:Explain conceptually how this process works to transfer energy from one object to another, or from one place to another (graphics will add greatly to the discussion here).
- Paragraph 2:Provide specific examples of where and how this process takes place in Earth’s atmosphere.
