The Greenhouse Effect By Tala Barcena What is
The Greenhouse Effect By: Tala Barcena
What is the greenhouse effect? Has it always been present in our atmosphere? § Radiation (electromagnetic radiation) § Visible light, Infrared radiation, Ultraviolet rays § Short -wave solar radiation § Long wave radiation (terrestrial radiation) § Absorption and Reradiation What are the greenhouse gasses? How do they help regulate global temperatures? What are the sources for these gasses? What happens when matter absorbs light? § Reflection § Absorption § From incident light to kinetic energy to thermal energy Is it good or bad? barreirofisica. wordpress. com
