Question 750Navigation General
70% to passYou can expect frontal activity when two air masses collide and _______________.
A
there are no significant differences between their temperatures and moisture content
B
there are significant differences between the temperature of each air mass
C
their barometric pressures and temperatures are the same
D
there are differences in how they track along the jet stream
AI Explanation
The correct answer is B) there are significant differences between the temperature of each air mass. When two air masses with significantly different temperatures collide, it creates a frontal system. The temperature difference between the air masses causes pressure differences, which leads to the formation of a front. This frontal activity can result in weather changes, such as precipitation, wind shifts, and temperature changes. The other options are incorrect because they do not accurately describe the conditions necessary for frontal activity to occur.
