Answer 2

The answers that apply;

1. They cause oceanic winds to carry water vapor
2. They move warm air masses in certain directions.
3. They affect the movement of winds that come from oceans

Prevailing winds blow predominantly in one area of the earth and are mainly influenced by the sun and its position. The sun creates pressure systems. Cooler air masses in higher pressure systems blow towards the low-pressure systems with warm rising air. When the prevailing winds travel over oceans, they carry with them moisture and bring it inland causing precipitation.
