Communication is a very vital part of a research by a scientist like you. The typical methods of classroom scientific communication include lectures, lab reports, term papers and poster presentations. Writing papers can help you enhance your your science productivity and at the same time retaining some body of knowledge that would be of help to future researches. The presentations you make widens your connection and awareness to the community. Moreover, the discussions you make can facilitate learning and exchange of ideas.
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy. The remaining heat on the surface is sent out into space in the form of infrared radiation.
