What will most likely happen when a warmer air mass exists above a polar ice sheet? the temperature of the ice sheet will be lowered. heat will be transferred from the air mass to the ice. the air mass will exert high pressure and rise upwards. air higher up in the mass will become cooler than air lower down.

Option (b) is the correct answer.

Explanation:

When warm air will rise above a polar ice sheet then it means due to high kinetic energy between the warm air molecules they will collide rapidly and frequently from one place to another.

As a result, warm air molecules will expand at a faster rate. As polar ice sheet is colder in nature therefore, it will absorb the heat from warm air.

Hence, the polar ice sheet will start to melt as absorption of heat will generate kinetic energy between the molecules of polar ice sheet.

Thus, we can conclude that heat will be transferred from the air mass to the ice.
