Solar Radiation

Solar radiation refers to the energy emitted by the sun in the form of electromagnetic waves. This radiation is essential for sustaining life on Earth and drives various natural processes such as the water cycle, photosynthesis, and climate patterns.

Types of Solar Radiation

There are three primary types of solar radiation:

1. Ultraviolet (UV) radiation: This is the highest energy solar radiation and is responsible for causing sunburn and other skin damage.
2. Visible light: This is the portion of solar radiation that is visible to the human eye and is essential for photosynthesis in plants.
3. Infrared (IR) radiation: This is the lowest energy solar radiation and is responsible for heating the Earth's surface.

Effects of Solar Radiation

Solar radiation has several effects on the Earth and its atmosphere:

• Heating of the Earth: Solar radiation warms the Earth's surface, leading to temperature variations across the planet.
• Photosynthesis: Plants use solar radiation to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.
• Weather patterns: Solar radiation drives the Earth's weather systems, influencing winds, ocean currents, and atmospheric circulation.
