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!
When one thinks of North Carolina’s Roanoke City, the first thing that probably comes to mind is the impressive valley that looms in front of the city. But there is so much more to Roanoke than just the valley – from the charming downtown to the rolling farmland that surrounds it, the city has something for everyone.
Roanoke is located in the southwestern corner of the state, bordered by the Blue Ridge Mountains to the north and the Roanoke River to the south. The city is about suburb southeast of the state capital of Raleigh and about 80 miles south of the eastern border of Virginia.
The city’s weather is mostly mild, with average highs in the upper 30s and lows in the upper 20s. The city’s weather can change quickly, so be sure to bring something warm to wear no matter the season.
Roanoke is a popular tourist destination due to its history, architecture, and natural beauty. The city’s most popular attractions include the valley, the Roanoke College campus, and the Roanoke Memorial Museum.
}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.
