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!
Newdale is a city in Iowa, United States. Located in Pottawattamie County, it is part of the Des Moines–West Des Moines Metropolitan Statistical Area. As of the 2010 census, the city population was 8,482.
Newdale was established in 1858. It was named for H.W. Newdale, an early settler. The city served as the main railroad hub between the Missouri River and Des Moines. It was also connected to the Chicago, Rock Island and Pacific Railroad, and the Western Union Telegraph Company.
Newdale grew rapidly in the early days of railroading and became one of the most important cities between Council Bluffs and Kansas City. By 1909, it had a population of 8,244 people and boasted 6 newspapers, 3 banks, two churches, and two public schools.
Today, Newdale retains much of its early Railroad and Manufacturing past. The city is home to Overland Park Technology Center, the first purpose-built major technology park in the United States. The technology park is home to several startups and established companies, including Garmin, IO
}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.
