Blue Planet

The surface of the Earth is composed of land and oceans, with the ocean covering the vast majority, hence the Earth is also known as the 'Blue Planet'. The total area of the ocean is about 360 million square kilometers, accounting for approximately 71% of the Earth's surface area; The average depth is about 3795 meters, and the total water volume is about 1.35 billion cubic kilometers, accounting for about 97% of the total water volume on Earth. The central body of the ocean is called the "ocean", and the part connected to the land at the edge is called the "sea". The two are interconnected, forming a unified and continuous body of water. Different sea areas have unique climate characteristics and rich biodiversity. This vast ocean not only shapes the natural appearance of the earth, but also provides a home for countless marine creatures to survive.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Most of the Earth's surface is covered by blue oceans, hence it is also known as the 'blue planet'. Currently, 71% of the Earth's surface is occupied by oceans, while the remaining 29% is land. The vast bodies of water on the Earth's surface that are separated by continents and interconnected are collectively referred to as oceans, with the central part of the ocean called the ocean and the peripheral part called the sea. All oceans in the world are interconnected, forming a unified body of water that is also a major driving force for global weather and climate. Minor fluctuations in ocean temperature can trigger drastic changes in weather and climate around the world. The movement of seawater is mainly divided into three types: wave motion, tides, and ocean currents. The water in the sea always flows and circulates continuously according to certain rules, and this regular flow of seawater is called ocean currents. The formation of ocean currents is the result of a combination of multiple factors and follows certain laws. Ocean currents affect various physical, chemical, biological, and geological processes in the ocean.
