The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
The tropopause is defined as the lowest level at which the lapse rate decreases to 2°C/km or less, provided that the average lapse-rate, between that level and all other higher levels within 2.0 km does not exceed 2°C/km. [1] The tropopause is a first-order discontinuity surface, in which temperature as a function of height varies ...
Tennessee is in the Southeastern United States.Most of the state is considered part of the Upland South, and the eastern third is part of Appalachia. [1] Tennessee covers roughly 42,143 square miles (109,150 km 2), of which 926 square miles (2,400 km 2), or 2.2%, is water.
Map of the United States with Tennessee highlighted These directional signs in Crossville, photographed in 1937 by Ben Shahn as part of a New Deal program, helped travelers find their way to other Tennessee cities and towns. Tennessee is a state located in the Southern United States. There are 346 municipalities in the state of Tennessee.
The temperature of the thermopause could range from nearly absolute zero to 987.547 °C (1,810 °F). Below this, the atmosphere is defined to be active [ clarification needed ] on the insolation received, due to the increased presence of heavier gases such as monatomic oxygen.
The lower part of the thermosphere, from 80 to 550 kilometres (50 to 342 mi) above Earth's surface, contains the ionosphere. The temperature of the thermosphere gradually increases with height and can rise as high as 1500 °C (2700 °F), though the gas molecules are so far apart that its temperature in the usual sense is not
HGTV just released its list of the 50 best small towns to visit for Christmas, with one for each state. HGTV says they each deliver major holiday spirit, and the Smoky Mountains' Gatlinburg was ...
The figure on the left shows an example of monthly temperatures recorded in the city of Campinas, Brazil, which lies approximately 60 km north of the Tropic of Capricorn at 22 degrees latitude. Average yearly temperature is 22.4 °C, ranging from an average minimum of 12.2 °C to a maximum of 29.9 °C.
