2. Which map shows the two correctly labeled air masses that frequently converge in the central plains to cause tornadoes?

3. Which type of frontal boundary is represented here?
Why does the mT air rise at this frontal boundary?
Less Dense

4. Which diagram below best represents the frontal boundary (fb) between point C and D as shown in the map?

5. Because it is less dense
Base your answers to questions 57 through 59 on the cross section below, which shows 2 weather fronts moving across N Y State. Lines X and Y represent frontal boundaries. The large arrows show the general direction the air masses are moving. The smaller arrows show the general direction warm, moist air is moving over the frontal boundaries.
57 Which type of front is represented by letter X? [1]
58 Explain why the warm, moist air rises over the frontal boundaries. [1]
59 Which type of front forms when front X catches and overtakes front Y? [1]
COLD
Because it is less dense
OCCLUDED
