since we live at the surface of the earth, stratosphere would be the layer of the atmosphere.
since we live at the surface of the earth what layer of the atmosphere would this be?
stratosphere
earth's atmosphere consists of a number of layers that differ in properties such as composition, temperature and pressure. the lowest layer is the troposphere, which extends from the surface to the bottom of the stratosphere. three quarters of the atmosphere's mass resides within the troposphere, and is the layer within which the earth's terrestrial weather develops. the depth of this layer varies between 17 km at the equator to 7 km at the poles. the stratosphere, extending from the top of the troposphere to the bottom of the mesosphere, contains the ozone layer. the ozone layer ranges in altitude between 15 and 35 km, and is where most of the ultraviolet radiation from the sun is absorbed. the top of the mesosphere, ranges from 50 to 85 km, and is the layer wherein most meteors burn up. the thermosphere extends from 85 km to the base of the exosphere at 400 km and contains the ionosphere, a region where the atmosphere is ionised by incoming solar radiation. the ionosphere increases in thickness and moves closer to the earth during daylight and rises at night allowing certain frequencies of radio communication a greater range. the kármán line, located within the thermosphere at an altitude of 100 km, is commonly used to define the boundary between earth's atmosphere and outer space. the exosphere begins variously from about 690 to 1,000 km above the surface, where it interacts with the planet's magnetosphere. each of the layers has a different lapse rate, defining the rate of change in temperature with height.
atmosphere
using solar power on the martian surface is challenging because the martian atmosphere has a significant amount of dust suspended in it. in addition to blocking sunlight from reaching mars's surface, dust particles gradually settle out of the air and onto objects. as "pathfinder" was nasa's first mars surface mission to be solar-powered, the effect of martian dust settling on solar cells was not well understood before the mission. it was predicted at the time that dust particles in the martian atmosphere would settle on the solar cells powering "pathfinder", blocking sunlight from striking them and slowly causing "pathfinder" to lose power. since knowing how the settling of dust out of mars's atmosphere would affect solar cell performance would be critical to subsequent solar-powered missions on mars, the mae was included aboard the "sojourner" rover to measure the degradation in performance of a solar cell as dust settled.
