Final answer:
Latitude influences temperature directly, which can in turn affect humidity levels, as well as vegetation distribution due to the different climates along various latitudes. Therefore, the correct answers are Humidity and Temperature.
Step-by-step explanation:
Latitude significantly influences both temperature and vegetation patterns globally. As one moves from the equator towards the poles, there is a noticeable change in biomes, which include tropical, subtropical, temperate, boreal, and Arctic regions. The reason for this is that the angle at which the sun's rays strike Earth changes with latitude, affecting both temperature and the types of plants that can grow. Likewise, humidity levels can also be affected since warmer temperatures near the equator can result in higher evaporation rates, contributing to more significant humidity.
Given the choice of options provided to the student question, the correct answers in terms of what latitude influences would be temperature and to some extent humidity as well, because it impacts temperature which in turn can affect moisture levels. Therefore, the most accurate answer from the options given would be E. A & D - Humidity and Temperature.
