The term near space is sometimes used, This term does not have a technical definition, but typically refers the region of the atmosphere up to 100 km, roughly between the Armstrong limit … At the top of the mesosphere is another transition zone known as the mesopause. The mesosphere lies between the thermosphere and the stratosphere. Poverty contributes greatly to many environmental problems. As you get higher up in the mesosphere, the temperature gets colder. The mesosphere, stratosphere and the lowest part of the thermosphere are collectively referred to as the middle atmosphere, which spans heights from approximately 10 kilometres to 100 kilometres. 5. The base of the mesosphere is defined as the temperature maximum existing at the top of the stratosphere, with the boundary between the two regions usually called the stratopause. Atmosphere layers University of Calgary climate scientist and geoengineering expert David Keith has suggested that we might ultimately find a particle that can be placed still higher up in the atmosphere, in the region called the mesosphere , above the ozone layer, where it would cause fewer problems. Meaning of mesosphere. The winds at these high levels are assumed to be geostrophic. Definition stratospheric ozone is good for humans but tropospheric is not, it is produced by smog and lies in the tropospheric zone. Troposphere definition, the lowest layer of the atmosphere, 6 miles (10 km) high in some areas and as much as 12 miles (20 km) high in others, within which there is a steady drop in temperature with increasing altitude and within which nearly all cloud formations occur and weather conditions manifest themselves. It extends to a depth of about 60 miles (100 km). Mesosphere: ADVERTISEMENTS: This layer has been so named because of its situation in the middle of the five layers that is divided according to the thermal conditions of the atmosphere.
