Which statement describes the general pattern of winds near the equater?

• Winds are generally weak because the equator is a region of mostly low air pressure.

• Winds are generally weak because the equator is a region where low and high air pressure atmospheric bands come together.

• Winds are generally strong because the equator is a region where low and high air pressure atmospheric bands come together.

• Winds are generally strong because the equator is a region of mostly high air pressure
