Atmospheric temperature usually decreases with altitude, but sometimes this phenomenon gets reversed in the troposphere. This phenomenon is known as _________.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Temperature Inversion.
The phenomenon where atmospheric temperature increases with altitude instead of decreasing is known as temperature inversion. This reversal of the normal temperature gradient occurs mainly in the troposphere, the lowest layer of the atmosphere. During a temperature inversion, a layer of warm air sits above cooler air near the Earth's surface, trapping pollutants and restricting vertical air movement. It often happens during clear nights, especially in valleys or urban areas, when the ground loses heat rapidly. Temperature inversion can lead to smog formation and poor air quality, affecting health and weather patterns. It typically lasts until the sun rises and warms the surface.
