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!
Unalaska city is located on the small island of Unalaska in the Aleutian Islands region of Alaska. The city's total area is just over 5 square miles, and the population was just over 7,000 as of the 2010 census. The city is bordered on the east by the Pribilof Islands National Historical Park, and on the south and west by the Bering Sea. Unalaska is the most eastern city in the United States.
Unalaska has a continental climate, which is typified by very cold winters and warm summers. Precipitation is frequent and high, but is most noticeable during nor'easters. As a result, the city frequently experiences heavy flooding, which can be disastrous.
Unalaska is the capital of the Bristol Bay region, which is one of the most remote and economically important parts of Alaska. The city is also the southernmost major city in the United States. The nearest states are Oregon to the west, and Russian America to the east. The nearest major capital is Anchorage, which is approximately 270 miles to the east.
}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.
