1. which kind of front is best for farmers? why?

Explanation:

1. A warm - front occurs when a warm air mass slides over a cold air mass, producing gentle rain showers.
2. An occluded front forms when a cold front catches up with a warm front, involving three air masses (the cold air mass of the cold - front, the warm air mass, and the cold air mass ahead of the warm - front).
3. A cold front is most likely to produce violent thunderstorms as cold, dense air rapidly pushes under warm, moist air, causing rapid uplift and instability.
4. A stationary front occurs when two air masses are relatively immobile, and it can last for days.
5. A warm front is likely to be followed by warm temperatures and higher humidity as the warm air mass replaces the cold air mass.
6. Density differences between air masses cause them to stay separated as denser air will not easily mix with less - dense air.
7. Along a front, warmer, less dense air is forced upwards as it is lighter than the colder, denser air.
8. A warm front is often best for farmers as it provides gentle, soaking rain which is beneficial for plant growth without causing the damage that can be associated with the heavy, intense rainfall of a cold front.

Answer:

1. Warm front
2. Occluded front
3. Cold front
4. Stationary front
5. Warm front
6. C. density differences
7. B. warmer, less dense air
8. Warm front; it provides gentle, soaking rain beneficial for plant growth.
