<span>When a cold front meets a warm front, the two cannot mix because of the difference in temperatures and densities. The result is that the warm air, being lighter, will usually be pushed atop the colder air. The air cools as it rises. As this happens, the water vapor in it condenses, forming clouds.</span>

Answer:
Desertification, nutrients in the soil, access to water, tools made for agriculture, location, climate, water pollution, the production of the food product, etc.
Explanation:
There are many factors that contribute in the decision making of food choices and the growth and production of food. In able to have a productive farm, some farmers choose to use many workers, some choose to use large tools, like tractors and irrigation systems. If there is not enough water getting to the farm, in some places like California, they will make a system or transport the water to the farm. Climate and weather also play a big role. If the climate does not supply the right resources to the plants, they will not be able to grow properly. Some climates are able to grow certain plants better than in other regions. The process of the food production affects how some make their food choices. For example, some people dislike how animals are treated and cared for before they are used for meat. Then, these people make the decision to not eat meat at all or from some companies that mistreat their animals. When their is water pollution near-by farms, farmers will struggle to grow their crops. When chemicals, from these polluted water sources, travel through the soil to the farms, the crops die or are harmed. In places like Africa, with dry climates, they use one plot of land for growing crops, then move to another plot the next year, because the nutrients from that plot were used all up for growing those plants. Sometimes, they even burn the weeds and shrubs after the harvest because it provides the soil with nutrients. This method is called slash and burn.
