The steam rising from the sea in Dalian is like a fairyland. What is the reason for the fog on the island?

This "boiling" phenomenon of the sea surface and the fog on the island are both caused by the change of water state.

When the sea surface "boils", the water in the sea water is heated and turned into steam, forming a large number of bubbles and steam, rising from the sea surface. In the process of rising, with the decrease of steam density, liquid water will be transformed into gaseous water again, making the whole sea surface look like "boiling", and the steam will rise and be spectacular.

Fog appears on the island because the temperature of seawater decreases at night, and the water vapor in the air will condense into water droplets or ice crystals to form fog. These fogs are the thickest in the morning, because the temperature is the lowest and the water vapor in the air is the easiest to condense. If there are natural barriers such as mountains around the island, it will form more obvious fog, making the island look like it is suspended in clouds.

In a word, these phenomena are all formed due to the change of the physical state of water, and they are beautiful wonders in nature.
