Question

which evidence best supports the answer to part a?
warm currents add moisture to the atmosphere, creating low - pressure areas that lead to cloud formation and rainfall.
warm and cold currents heat the land evenly, preventing pressure differences.
ocean currents do not influence air pressure or weather systems.
cold currents add moisture to the atmosphere, creating high - pressure areas that cause frequent storms.

Explanation:

Warm ocean currents add moisture to the atmosphere, leading to low - pressure areas which cause cloud formation and rainfall. This is a well - known meteorological concept related to the influence of ocean currents on weather. The other options are incorrect as warm and cold currents do not heat land evenly (they have differential heating effects), ocean currents do influence air pressure and weather systems, and cold currents do not create high - pressure areas that cause frequent storms in the described way.

Answer:

Warm currents add moisture to the atmosphere, creating low - pressure areas that lead to cloud formation and rainfall.
