Which condition traps cooler air near the earth's surface and can lead to major drift?

  1. Temperature Inversion

  2. Runoff

  3. Vapor Drift

  4. Leaching

The correct answer is: Temperature Inversion

A temperature inversion is a condition where the normal decrease in temperature with height in the atmosphere is reversed, trapping cooler air near the surface. This can lead to major drift due to the difference in air densities and moisture levels between the trapped air and surrounding air. The other options, runoff, vapor drift, and leaching, are all processes that involve the movement of water or substances on the earth's surface and do not directly relate to the trapping of cooler air.
