Final answer:
Convection is the movement of mass caused by the tendency of hotter, less dense material to rise and colder, denser material to sink under the influence of gravity. In weather systems, convection drives the formation of clouds, thunderstorms, and hurricanes. A real-world example of convection can be seen in the movement of air masses associated with weather fronts.
Step-by-step explanation:
The event described in the question is known as convection. Convection is the movement of mass caused by the tendency of hotter, less dense material to rise and colder, denser material to sink under the influence of gravity. In this case, as a cold air mass moves underneath a warm air mass, the warmer air rises, creating convection currents.
Convection is an important process in weather systems. It plays a role in the formation of clouds, as the rising warm air causes moisture to condense and form clouds. Convection also drives thunderstorms and hurricanes as warm, moist air rises and releases energy in the form of precipitation and strong winds.
A real-world example of convection can be seen in the movement of air masses associated with weather fronts. When a cold front pushes underneath a warm front, the warm air is lifted, creating unstable conditions and the potential for thunderstorms.
