Answer:
B
Step-by-step explanation:
Wind is known as the movement of air molecules from one place to another, and this can also be used as a definition for a convection current.
Convection is the scientific phenomenon where by air molecules become less dense as they get hotter, and as they become less dense, they rise higher into the air. While this happens, colder molecules move into the space where the previous molecule was, and as that one rises, another takes its place. So we are stuck with a continuous loop of moving air molecules. If enough air molecules experience this, such as heating over a large area, affecting a lot of molecules, then wind patterns are created.
