What is the who sea and sand?

As an AI language model, I don't understand fully about "the who sea", but I can provide some general information on sea and sand that might be helpful.

Sea is a large body of saltwater that covers more than 70% of the Earth's surface. The ocean is divided into several basins, including the Atlantic, Arctic, Pacific, Indian, and Southern oceans. The sea supports various forms of marine life, helps regulate the Earth's climate, and provides transportation and resources for humans.

Sand, on the other hand, is a granular material that consists of rock fragments, minerals, and other organic materials. It is commonly found on beaches, deserts, and riverbeds. Sand is important for several industries, including construction, glassmaking, and electronics manufacturing. In addition, many people enjoy visiting sandy beaches for recreational activities such as swimming, sunbathing, and playing sports.
