Electromagnetic radiation (EMR) refers to the energy that is transmitted in the form of electromagnetic waves through space or a medium. These waves consist of oscillating electric and magnetic fields that are perpendicular to each other and travel at the speed of light. EMR interacts with the Earth and its atmosphere in various ways, including absorption, reflection, and transmission.

Absorption occurs when EMR is absorbed by molecules and particles in the atmosphere. This absorption can occur at specific wavelengths, known as absorption bands, where certain molecules and particles are particularly effective at absorbing EMR. The absorbed EMR can be converted into other forms of energy, such as heat, which can affect the temperature and composition of the atmosphere.

Reflection occurs when EMR is reflected off the surface of the Earth or off ______ _______ _________ _________ _________ ___ ______ ___.
