    The exosphere, which does not have a definite boundary. The lower boundary of the?exosphere can vary in altitude from 500 to 1000 kilometers depending on how active the Sun is.

    I would call it the atmosphere, myself, but it depends on how you are defining the term "earth".  The uppermost (outermost) layer of the solid earth is called the crust.
