The thermosphere is an upper atmospheric layer that includes the ionosphere (a layer within it defined by ionized particles) and the exosphere, which forms its outermost region. The mesosphere, stratosphere, and troposphere are distinct lower/separate atmospheric layers, not part of the thermosphere.

exosphere and ionosphere
