Question

1. which factor causes atmospheric pressure? (1 point)

sizes and shapes of clouds
air currents in the atmosphere over the ocean
weight of the atmosphere above a surface
altitude above sea level

Explanation:

Atmospheric pressure is defined as the force exerted per unit area by the weight of the air above a surface. Cloud sizes/shapes relate to weather but not pressure cause. Air currents are effects of pressure differences, not the cause. Altitude affects pressure magnitude (lower as altitude increases) but it's the weight of the air column (atmosphere above) that fundamentally causes atmospheric pressure.

Answer:

weight of the atmosphere above a surface
