which image represents the air mass movement associated with a stationary front?
Answer
Brief Explanations:
A stationary front occurs when a warm - air mass and a cold - air mass meet and neither is strong enough to displace the other. The air masses remain in place relative to each other. In the correct image, the cold air and warm air are in contact with little to no horizontal movement of one over the other. The third image shows cold air and warm air meeting with arrows indicating they are not moving past each other horizontally, which is characteristic of a stationary front.
Answer:
The third image (where Cold air and Warm air are facing each other with arrows indicating no horizontal displacement of one over the other)
