To sail the ocean, a captain's license, also known as a Merchant Mariner Credential (MMC), is required.

These planets have a variety of surface features and may have different compositions and atmospheres that make them distinct from ocean planets. **

The Atlantic Ocean is generally rougher than the Indian and Pacific Oceans due to its location and weather patterns. The Atlantic Ocean is more exposed to strong winds and storms coming from the west, which can create larger waves and rougher conditions. Additionally, the Atlantic Ocean is narrower than the Indian and Pacific Oceans, which can amplify wave heights and make the water choppier. The combination of these factors contributes to the Atlantic Ocean being rougher compared to the other two oceans. **

To sail the ocean, you do not need a driver's license. Instead, you would need a captain's license or a boating license, depending on the size and type of vessel you are operating.

Additionally, underwater volcanic activity also releases minerals and salts into the ocean, contributing to its salinity. The most common salt in the ocean is sodium chloride, which is the same salt found in table salt. **
