Why do thermals rise from the town?

Thermals rise from towns primarily due to the uneven heating of surfaces. Urban areas, with their concrete and asphalt, absorb and retain heat more effectively than surrounding natural landscapes, leading to localized warming. As the air above these warmer surfaces heats up, it becomes lighter and rises, creating thermals. This process is further enhanced by factors like human activities and infrastructure that contribute to the overall heat in the area.
