Daylight is the natural light that comes from the sun during the day. It occurs when the sun rises above the horizon, illuminating the Earth and providing visibility. Daylight varies in intensity and duration throughout the year due to the tilt of the Earth's axis and its orbit around the sun. This light is essential for many processes, including photosynthesis in plants, which helps produce oxygen and food. Daylight also influences human activities, as people often rely on it for work and recreation. The presence of daylight can affect mood and well-being, making it an important aspect of daily life.
