Answer:
Wind
Step-by-step explanation:
The surface of the earth is heated in unequal proportions at different places. In addition to this, the atmosphere also is heated unequally. Due to this, there occurs wind, which is mainly caused due to pressure differences from one location to another. This wind blows from a region of higher pressure to a region of low pressure in a horizontal manner and replaces the warm air by cold air.
Wind plays a significant role in maintaining the weather and the climate pattern of an area. This wind blows both over the surface of the land as well as oceans or seas.
