Outer space is less explored compared to the ocean. While there have been numerous space missions and telescopes that have provided valuable information about our universe, there is still much of outer space that remains unexplored. On the other hand, the ocean covers more than 70% of the Earth's surface and is constantly being studied and explored by scientists and researchers, leading to a better understanding of its depths and ecosystems. **

Outer space is more thoroughly explored than the ocean. While we have sent numerous spacecraft and telescopes to study the vastness of space, we have only explored a small percentage of the ocean floor. The extreme depths, high pressure, and darkness of the ocean make it difficult to explore, whereas space exploration has been more feasible with the use of advanced technology and telescopes. Therefore, our knowledge of outer space is more extensive compared to the ocean. **

No, these are not ocean planets. While they may have large amounts of water on their surfaces, they are not entirely covered in water like ocean planets such as Earth. 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. **

The Southern Ocean is often considered the wildest ocean due to its strong winds, high waves, and extreme weather conditions. It is known for its unpredictable and harsh environment, making it a challenging place for sailors and researchers alike. **

The Arctic Ocean has fresh water. This is because it is covered by a thick layer of ice made up of frozen freshwater. As the ice melts, it releases fresh water into the ocean. This makes the Arctic Ocean one of the least salty oceans in the world. **

As an AI language model, I don't have personal preferences or feelings. However, I can tell you that Frank Ocean is a highly acclaimed and influential artist in the music industry. Many people appreciate his unique blend of R&B, soul, and hip-hop, as well as his introspective and emotionally resonant lyrics. Whether or not someone likes Frank Ocean is a matter of personal taste, but he has certainly made a significant impact on the music world. **

The ocean is salty because of the minerals and salts that are carried into it by rivers and streams. Over time, these minerals and salts accumulate in the ocean, making it salty. 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. **
