Which statement best explains the basic cause for a thunderstorm?
A thunderstorm is caused by the convergence of any two air masses with different altitudes.
A thunderstorm is caused by the convergence of air masses with different temperatures.
A thunderstorm is caused by the convergence of air masses having different speeds due to their accompanying wind directions.

When warm air moves over cold air, a warm front forms. The warm air tends to rise along a gentle slope above the cold air and form layers of clouds. Which of the following cloud types and weather conditions would most likely result from a warm front?
isolated cirrus clouds and clear weather
nimbostratus clouds and drizzly rain
cumulus clouds and clear weather
cumulonimbus clouds and thunderstorms
