Answer:
Cold Fronts
Explanation:
Fronts are geograpghical terms that describes various boundaries between air masses of different temperatures.
There are frour different type of fronts, they includes:
1. Cold fronts
2. Warm fronts
3. Stationary fronts
4. Occluded fronts
However, from the question, the answer is Cold Front due to the following characteristics associated with cold front.
Cold front is term that describes the movement of front in which cold air is replacing warm air at the surface.
Some of the characteristics of cold fronts include the following
i. Cold fronts always move faster than all other types of fronts.
ii. Cold fronts is characterized by most violent weather among all types of
fronts.
iii. Cold fronts normally move the farthest while maintaining their intensity, while also associating with thunderstorms.
iv. Cold fronts usually bring cooler weather, clearing skies, and a sharp change in wind direction.
All the above characteristics are presented in the question. Hence, the answer is COLD FRONT.
