In the United States, the Bureau of Labor Statistics computes the consumer price index which is used to find inflation rates.

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.
During the time when Earth was forming and was in a molten state, heavy materials like iron and nickel sank to the center of the Earth's mass and lighter materials floated to the surface of the mass. The very center of what we call the core, is solid in the middle because of the increased pressure in that region.utside the core, the largest mass of planet Earth is called the mantle and this is mostly solid rock. The very outermost layer of our planet is about 30 miles thick, is made of lighter rocks, and is called the crust.
