Answer:
Cold Front 3 // Stationary Front 1 // Warm Front 2 // Occluded Front 4
Step-by-step explanation:
It's simple. Warm front means the warm air is pressing forward, which is why it's a warm front. Stationary Front, meaning they're at a standstill, also makes sense because stationary means not moving. Then since your last option is Occluded Front, since the others already have an answer, you have no choice but to match 4 with it. I took the quiz and got the answer right. :D
