From which layer of the atmosphere do particles of air escape into space? a.. troposphere b.. mesosphere c.. exosphere d.. stratosphere.

"Exosphere" is the layer of the atmosphere among the choices given in the question that particles of air escape into space. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has come to your great help.

Airplanes usually fly in the lower part of the stratosphere - there is nearly no water vapor and it's very dry, so it to avoid big turbulences. it's about 8-10 kilometers above ground (depending on weather conditions, region etc.)
