Answer:
The cultivation of crops alongside the rearing of animals for meat or eggs or milk defines mixed farming. For example, a mixed farm may grow cereal crops such as wheat or rye and also keep cattle, sheep, pigs or poultry. Often the dung from the cattle serves to fertilize the cereal crops.
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
