Answer:
Volcanic gases. (Ans A)
Explanation:
Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.
In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then <span>strengthen and organize to form hurricanes. Hope this helps:)
