Sunlight

Sunlight is a form of electromagnetic radiation given off by the Sun. It is the primary source of energy for life on Earth and plays a crucial role in various natural processes, including photosynthesis, the water cycle, and the Earth's climate.

Key Facts about Sunlight:

• Sunlight is a combination of different wavelengths of light, including visible light, ultraviolet (UV) light, and infrared (IR) light.
• The Earth receives sunlight in the form of solar radiation, which provides the energy necessary for sustaining life and driving weather patterns.
• Plants use sunlight to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.
• Sunlight also plays a role in regulating the Earth's temperature and climate through the absorption and reflection of solar energy by the Earth's surface and atmosphere.
