Atmosphere
Gases form the layers surrounding the Earth, essential for supporting life and regulating climate. It consists of Nitrogen (78%), oxygen (21%), and trace gases like argon and carbon dioxide
Greenhouse gases
Are gases in the atmosphere, such as carbon dioxide and methane, that trap heat and contribute to the greenhouse effect, influencing global temperatures and climate.
Albedo
The reflectivity of a surface that reflects heat into the atmosphere and space
Differential Heating
Uneven heating of Earth's surface leads to atmospheric circulation.
Solar radiation is more intense at the equator and weaker at the poles.
This creates temperature gradients that drive atmospheric movement.
Clouds
Reflect(Albedo) Infrared Radiation from the sun, cooling earth, especially after temperature increases because more evaporation=more clouds
Absorbs Infrared Radiation from the Earth’s surface back into the Earth, increasing/trapping heat and increases temperature
Albedo
How reflective surfaces are to the sun’s heat; more=cooler temperature
Infrared Radiation/Solar Energy
Energy from sun. 30% of the energy is reflected back into space, and 70% is absorbed by Earth. Earth's surface emits infrared radiation, which is absorbed and re-emitted by greenhouse gases.
Electro magnetic radiation
Electromagnetic radiation is a form of energy that is propagated through space or matter in the form of waves at speed of light
UV radiation
Ultraviolet (UV) radiation is a form of electromagnetic radiation emitted by the sun that is harmful to plants and animals such as skin aging, wrinkling, skin cancer, worse plant growth, and DNA damage
It is categorized into three main types based on wavelength:UVA , UVB, UVC
Ozone layer
The ozone layer is a region in Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation, preventing a lot of it from reaching the Earth’s surface.
