Which factor does not contribute to the formation of condensation?

The formation of condensation primarily hinges on the presence of moisture in the air, temperature variations, and atmospheric conditions. High humidity, cold temperatures, and temperature drops all play significant roles in the condensation process. When the air holds a lot of moisture (high humidity) and then experiences a drop in temperature, the air can no longer hold as much moisture, leading to condensation.

Cold temperatures are crucial because they can lower the capacity of air to retain moisture. As the temperature drops, water vapor turns back into liquid water, which is the essence of condensation.

High pressure systems typically lead to stable and dry atmospheric conditions, which do not promote the accumulation of water vapor necessary for condensation. In fact, these systems are often associated with clear skies and lower humidity levels, making them less conducive to condensation compared to scenarios influenced by high humidity and temperature drops. Thus, high pressure systems do not contribute to the formation of condensation, making this the correct response.
