Question

A dryline causes uplift to occur because?

1) the intruding air mass has the same low humidity as the lifted air mass.
2) the intruding air mass is colder and more humid than the lifted air mass.
3) the lifted air mass is moister than the intruding air mass.
4) the lifted air mass is dryer than the intruding air mass.

Answer 1

A dryline causes uplift to occur because the lifted air mass is moister than the intruding air mass.

Step-by-step explanation:

A dryline causes uplift to occur because the lifted air mass is moister than the intruding air mass. A dryline is a boundary separating dry air from moist air. When the moist air mass encounters the dry air mass, the moisture in the lifted air mass condenses, leading to the formation of clouds and precipitation. This uplift is caused by the difference in humidity between the two air masses.
