Question

An air mass whose temperature is colder than the underlying surface is called a:

1) Warm air mass
2) Cold air mass
3) Stable air mass
4) Unstable air mass

Answer 1

A cold air mass has a temperature colder than the underlying surface and leads to stable atmospheric conditions. The correct answer is 2) Cold air mass.

Step-by-step explanation:

An air mass whose temperature is colder than the underlying surface is called a cold air mass.

Cold air masses typically form over polar regions and move towards lower latitudes. They have lower temperatures and higher densities compared to the underlying surface, leading to stable atmospheric conditions.

For example, in winter, cold air masses from the Arctic can move southward, bringing cold temperatures and potentially causing snowfall in areas that normally have milder climates.

An air mass whose temperature is colder than the underlying surface is called a cold air mass. When the air temperature is cooler than the surface, it means that the air mass is likely to remain close to the ground and not rise significantly, leading to increased stability in atmospheric conditions.

This is due to the fact that hot air is less dense and tends to rise, creating instability, while cold air is denser and tends to sink, promoting stability.
