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
By rename do you mean turn into an improper fraction?
if so, it is because without turning it into an improper fraction, you cannot subtract 3/4 from 1/4 because you would get a negative answer and that would be incorrect
