Atmosphere of Earth (see the temperature section, below). Because the general pattern of the temperature/altitude profile is constant and measurable by means of instrumented balloon soundings, the temperature behavior provides a useful metric to distinguish atmospheric layers. In this way, Earth's atmosphere can be divided (called atmospheric stratification) into five main layers. Excluding the exosphere, the atmosphere has four primary layers, which are the troposphere, stratosphere, mesosphere, and thermosphere. From highest to lowest, the five main layers are: The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at
What Where are represented by the patterns of dots on the television screen. What characters, what bodies, finally exist in "What Where" are created by voice, less absent presences than present absences." Beckett referred to the lit playing area in this production as the "field of memory". "The clear indication is that what we are seeing is both a memory and a scenario: instructions come from the megaphone, the Voice of Bam controls what we see, puts the characters through their movements rapidly without words like a film running over its spools at rewind speed, and then starts again, occasionally stopping when
