Question

After a cold front passes, the temperature ________ and the pressure ________ (relative to the conditions that existed prior to the passage of the front).
a. decreases; increases
b. decreases; decreases
c. increases; decreases
d. increases; increases

Answer 1

Answer:

a. decreases; increases

Explanation:

When a mass of cold air is moving in its advance to another mass of warmer air, it is said that we are in the presence of a COLD FRONT. Associated with the passage of the cold front, there is an increase in pressure (a decrease in pressure is previously recorded), wind rotation, decrease in temperature and humidity, improved visibility and elevation of cloud tops.

The passage of a cold front is not always associated with the occurrence of precipitation. Sometimes a mere increase in cloudiness can be evidenced, and in other cases heavy rains or storms.
