We are quite familiar with the first layer, the crust, since we walk on it every day, dig holes in it, and so on. It is the outer layer of the Earth and is actually between 5 and 25 miles thick depending on location. founder of bain and company

This is the outermost layer of the atmosphere. It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is a transition layer called the thermopause. disadvantages of the gibbs reflective cycle
