A Correct answer
Explanation

Thermals are columns of rising warm air created by uneven solar heating of the Earth's surface. Different surfaces (asphalt, grass, water, plowed fields) absorb heat at different rates, creating warm air pockets that become buoyant and rise. Jet streams (B) are high-altitude winds, counterclockwise circulation (C) relates to pressure systems, and temperature inversions (D) actually suppress vertical air movement.
