The density of the Earth's atmosphere decreases nearly exponentially with altitude. The total mass of the atmosphere is M = ρ A H ≃ 1 kg/cm 2 within a column of one square centimeter above the ground (with ρ A = 1.29 kg/m 3 the atmospheric density on the ground at z = 0 m altitude, and H ≃ 8 km the average atmospheric scale height).
The thermosphere is the second-highest layer of Earth's atmosphere. It extends from the mesopause (which separates it from the mesosphere) at an altitude of about 80 km (50 mi; 260,000 ft) up to the thermopause at an altitude range of 500–1000 km (310–620 mi
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.
Earth's turbopause lies near the mesopause, at the intersection of the mesosphere and the thermosphere, at an altitude of roughly 90 km (56 mi). [2] Some other turbopauses in the Solar System that are known include Venus' turbopause at about 130–135 km (81–84 mi), Mars' at about 130 km (81 mi), Jupiter's at roughly 385 km (239 mi), and ...
"1, 2 Step" is a song by American singer Ciara featuring American rapper Missy Elliott. Written alongside producer Jazze Pha , it was released on November 1, 2004, as the second single of the former's debut studio album, Goodies .
The troposphere contains the boundary layer, and ranges in height from an average of 9 km (5.6 mi; 30,000 ft) at the poles, to 17 km (11 mi; 56,000 ft) at the Equator. [ 3 ] [ 4 ] In the absence of inversions and not considering moisture , the temperature lapse rate for this layer is 6.5 °C per kilometer, on average, according to the U.S ...
Claire Richards (born 17 August 1977) is an English singer and member of the pop group Steps.As a solo artist, Richards has released two studio albums: her debut, My Wildest Dreams, was released in 2019 and Euphoria, a covers album, was released in 2023.
The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
