At many coasts here, it means that there is a convergence of different elements such as land, water, and air. This convergence creates a unique and dynamic environment that is constantly changing due to natural forces like tides, waves, and weather patterns. Coasts are also important habitats for a diverse range of plant and animal species, making them ecologically significant areas. Additionally, coasts often have cultural and economic importance, serving as locations for recreation, tourism, and economic activities such as fishing and shipping. **

Seawater can be warm at coasts in winter due to several factors. One reason is the presence of warm ocean currents that flow near the coast, bringing warmer water from tropical regions. Additionally, shallow coastal waters can heat up more quickly than deeper offshore waters, especially when exposed to sunlight. Lastly, urban areas near the coast can contribute to warmer seawater temperatures through the release of heated water from industrial processes or urban runoff. **

The Baltic Sea is surrounded by several fjord coasts, including the Oslofjord in Norway, the Gdańsk Bay in Poland, and the Kiel Fjord in Germany.

Yes, national borders do extend into the seas along the coasts. Each country has a territorial sea that extends 12 nautical miles from its coastline, over which it has full sovereignty. Additionally, countries can also claim an exclusive economic zone (EEZ) that extends 200 nautical miles from their coastline, within which they have exclusive rights to explore and exploit natural resources. Therefore, national borders do extend into the seas along the coasts, and countries have jurisdiction over these maritime areas. **
