Most people know that sunset is the time when the sun goes down. But did you know that the sun doesn't actually set? Instead, Earth rotates into darkness, giving us the illusion that the sun is setting. So what causes sunset?
Well, it's a combination of things. The Earth's atmosphere scatters sunlight in every direction, but blue and violet light are scattered more than other colors. This is why the sky is usually blue during the daytime. As the sun gets lower in the sky, the atmosphere becomes thicker and more dense.
This scattering of sunlight happens to a greater extent, and we see red and orange light more than blue and violet light. That's why sunset is usually a beautiful red or orange color. So next time you see sunset, remember that you're actually seeing Earth rotate into darkness!
Ogden is a city in Weber County, Utah, situated at the western end of the Ogden Valley. The population was 147,224 at the 2010 census. Ogden is a major transportation hub for the Wasatch Front, and is noted for its scenery, which includes mountain and valley views. The city is the county seat of Weber County. The city was founded by the Weber County people in 1846, and was originally named Fort Weber. The city was named Ogden in 1851 in honor of General David O. Ogden, a veteran of the Mexican-American War and the Oregon Trail. Ogden was the first city in Weber County, and the first city west of the Rocky Mountains. The city's economy is based on services, with a major concentration of government and financial services employers. Recreation is also a major economic force, with Ogden hosting the Wasatch Front's largest concentration of ski resorts, amusement parks, and golf courses. The city is home to the University of Utah, which has an enrollment of over 35,000 students.
}As the sun sets, the sky slowly grows dark. For many people, this is a time to relax and wind down for the day. But have you ever wondered exactly when it gets dark? The answer may surprise you.
Did you know that darkness actually begins long before the sun sets? As the sun gets lower in the sky, its light has to travel through more atmosphere. This filters out some of the blue light, making the sun look redder. At the same time, shadows get longer and darker. So by the time the sun finally dips below the horizon, darkness has already begun to fall.
Of course, not all places on Earth experience darkness at the same time. Near the equator, the sun sets and rises almost directly overhead. This means that there is less of a difference between daytime and nighttime. Closer to the poles, however, the sun stays low in the sky for much of the year. This leads to longer periods of darkness during wintertime.
