When two air masses with different temperatures or humidity levels meet, they do not immediately mix or blend. Instead a line or boundary forms between them. This boundary is called a......<u>front</u>
Explanation:
Due to the different properties, especially temperatures. The less-dense air mass tends to rise while the denser tends to dive at the front causing turbulence. There are four main types of fronts;
- Cold front – bring rainfall and thunderstorms
- warm front – associated with less intense weather
- Occluded front – when a warm air mass is in between two cool air masses
- Stationary front - can be warm or cold but barely moves
