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!
Given the global population growth rate of 2.4% and projected to rise to 3.2% by 2050, there is an increasing awareness of the need for cities to be more sustainable and efficient. Thankfully, over the past several years, many cities — both idealistic and pragmatic — have begun to emerge that align with these needs. This article discusses five of the most ideal cities to live in and work in, based on measures of sustainability, efficiency, and livability.
How to pick the ideal city
There's no definitive answer to this question, as different people have different priorities, needs, and wants. However, some of the important criteria that should be considered when choosing an ideal city include:
The ideal city should be located in a desirable geography, with good infrastructure and a stable population. It should be close to major cities, but also have a stable population, which lowers the need for expensive infrastructure.
The ideal city should be compact and walkable, with a rich diversity of cultures and natural features.
The ideal city should have a temperate climate with good weather year-round.
The ideal city should have a stable and growing economy, with opportunities for both employment and entrepreneurship.
The ideal city should have a comfortable and sustainable lifestyle, with a high quality of life.
}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.
