Solar radiation refers to the energy emitted by the sun in the form of electromagnetic waves. This energy travels through space and reaches the Earth, where it plays a crucial role in various natural processes and phenomena.

Types of Solar Radiation

Ultraviolet (UV) radiation: This type of radiation has a shorter wavelength and can cause sunburn and skin damage.
Visible light: This is the portion of the solar radiation that is visible to the human eye and is essential for photosynthesis in plants.
Infrared (IR) radiation: This type of radiation has a longer wavelength and is felt as heat.

Effects of Solar Radiation

Solar radiation has several important effects on Earth:

Heating the Earth's surface: The sun's energy warms the Earth, creating temperature variations that drive weather patterns and ocean currents.
Driving the water cycle: Solar radiation evaporates water from the Earth's surface, leading to the formation of clouds and precipitation.
Supporting life: Solar radiation is essential for photosynthesis in plants, which forms the basis of the food chain.
Causing sunburn and skin damage: Overexposure to UV radiation can harm human skin and eyes.
