In the United States, the Bureau of Labor Statistics computes the consumer price index which is used to find inflation rates. The bureau states that the consumer price index âis a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.â.
The earth ulis called a blue planet because of the presence of abundance of water in it. About 70 percent of the earth's crust is covered with water. And this imparts it with a blue colour as seen from the space.
Another reason why Earth is unique is that it is the only place in the solar system to our knowledge that has liquid water. Water is one of the key ingredients of life as we know it. The water on Earth's surface covers about 70 percent of our planet and its atmosphere, and it is what makes Earth appear blue from outer space. If you could cut Earth open, you would find that it has a very hot but solid core made up mostly of iron.
