Final answer:
When traveling south, the temperature and precipitation increase and the temperature is warmer and plant growth is possible
Step-by-step explanation:
When traveling south, the temperature and precipitation increase and the temperature is warmer and plant growth is possible when temperatures are warm enough to sustain plant growth, which occurs in the spring, summer, and fall. During much of the winter, temperatures are low, and water, which is stored in the form of ice, is not available for plant growth. When traveling south, the temperature and precipitation increase, resulting in warmer temperatures. This warmer temperature allows for plant growth and occurs in the spring, summer, and fall. However, during the winter months, temperatures are low and water is not available for plant growth.
