Sea or sea ice is the icy water of the sea. Because ice is less dense than water, it floats on the surface of the ocean (just as freshly frozen water, which has an even lower density, floats). The sea covers about 7% of the earth's surface and about 12% of the world's oceans. It is found in the north, in the Arctic Ocean, and the areas just below it, and other cold oceans, seas, and bays. In the South, ice forms in different areas around the South (continent). Most lakes are located in polar ice caps in the Earth's polar regions: the Arctic Ocean's ice mass and the Antarctic ice mass in the South Ocean. Arctic icebergs undergo a significant amount of displacement at sea level each year. This is a natural phase that depends on the ecology of the Arctic, which includes the ocean ecosystem. Due to winds, currents and temperature fluctuations, the sea is very active, transforming into different types of ice in different forms. The sea may be mountain ice, which is a mass of ice that separates from the bottom of a glacier or the edge of an ice sheet and floats on seawater. Depending on the location, the sea may expand and join.

Different shapes and dynamics

The sea does not form easily and does not melt easily. It is very dynamic during its duration. Due to the different actions of wind, sea currents and temperature fluctuations, the sea changes a lot. The sea is classified based on the speed of movement and the time it takes to form.
