The lower boundary of the exosphere, where it interacts with the thermosphere is called the thermopause. The thermosphere contains an appreciable concentration of elemental sodiumlocated in a 10-kilometre (6.2 mi) thick band that occurs at the edge of the mesosphere, 80 to 100 kilometres (50 to 62 mi) above Earth's surface. The sodium has an average concentration of 400,000 atoms per cubic centimeter. Ver mais The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.
