Answer:
Step-by-step explanation:
- Solar radiation: The most significant source of radiation energy on Earth is the sun. The sun produces a wide range of electromagnetic radiation, including visible light, ultraviolet (UV) radiation, and infrared (IR) radiation. These different types of radiation travel through space and reach the Earth's atmosphere, where they provide the energy that drives weather and climate patterns, and sustain all life on earth.
- Cosmic radiation: Cosmic radiation is a term used to describe the high-energy particles and radiation that originate outside of the Earth's atmosphere. Cosmic radiation includes particles such as protons and alpha particles, as well as gamma rays and x-rays. Some of this radiation is blocked by the Earth's atmosphere, but some reaches the surface and can be harmful to living organisms. Cosmic radiation can also be used for scientific research and exploration, such as in the field of astrobiology.
It's worth noting that the Earth's atmosphere and magnetic field play a crucial role in absorbing and deflecting some of these radiations and protecting life on Earth from harmful radiations.
