The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains approximately 75% of the atmosphere's massand 99% of the total mass of water vapor and aerosols.[2] The average height of the troposphere are 18 km (11 mi; 59,000 ft) in the tropics, 17 km (11 mi; 56,000 ft) in the middle latitudes, and 6 km (3.7 mi; 20,000 ft) in the polar regions in winter.
The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer. This layer is typically a few hundred meters to 2 km (1.2 mi; 6,600 ft) deep depending on the landform and time of day. Atop the troposphere is the tropopause, which is the border between the troposphere and stratosphere. The tropopause is an inversion layer, where the air temperature ceases to decrease with height and remains constant through its thickness.[3]
The word troposphere is derived from the Greek tropos (meaning "turn, turn toward, change") and sphere (as in the Earth), reflecting the fact that rotational turbulentmixing plays an important role in the troposphere's structure and behaviour. Most of the phenomena associated with day-to-day weather occur in the troposphere.
A common requirement of a PhD across different schools and countries is: D. a dissertation.
<h3>What is PhD?</h3>
PhD is an acronym for Doctor of Philosophy and it can be defined as the highest level of degree that is awarded to a graduate, especially after the completion of a masters degree (MSc.) in a particular course of study.
As a general rule, a dissertation is a common requirement from all students of a Doctor of Philosophy (PhD) across different schools and countries.
