Question

which fronts are shown?
○ item a shows a cold front, and item b shows a warm front.
○ item a shows an occluded front, and item b shows a cold front.
○ item a shows a warm front, and item b shows a stationary front.
☑ item a shows a stationary front, and item b shows an occluded front.

Explanation:

• Item A: A stationary front forms when cold and warm air masses meet but neither can push the other, creating a stalled boundary with widespread cloud cover, matching the diagram.
• Item B: An occluded front occurs when a fast-moving cold front overtakes a warm front, lifting the warm air mass completely off the ground, with layered air masses and intense precipitation as shown.

Answer:

Item A shows a stationary front, and item B shows an occluded front.
