The thermosphere is that region of neutral atmosphere in which atmospheric constituents are gravitationally bound to the Earth but are barometrically distributed according to their molecular or atomic weights. Unlike the lower atmosphere, mixing processes a reweak, which allows each constituent gas to behave independently. The thermosphere begins at about 100‐km‐altitude and extends up to 500 km or beyond. The temperature increases with height throughout the layer, which is a stabilizing influence.
