Question

Study the image, which shows warm and cold air fronts.

Warm and cold air fronts with points labeled 1 through 4. 1: cold air entering from the left and moving down. 2: clouds with rain. 3: warm air entering from the right and moving up. 4: warm air entering from the top left and moving down toward the clouds.

At which point does warm air begin to rise before colliding with cold air?

1
2
3
4

Answer 1

3

Point 3 shows the warm air rising (moving upward) as it rides up over the colder air ahead of the front, which leads to the clouds/precipitation at point 2.
