A sunset occurs when the sun dips below the horizon, marking the end of the day. This natural phenomenon is caused by the rotation of the Earth, which causes the sun to appear to move across the sky. As the sun sets, its light passes through more of the Earth's atmosphere, scattering shorter wavelengths and creating vibrant colors like orange, pink, and purple. Sunsets can be observed from various locations, including beaches, mountains, and urban areas. Many people enjoy watching sunsets for their beauty and tranquility. The experience can be enhanced by factors such as weather conditions, landscape features, and the presence of bodies of water, which can reflect the colors of the sky.
