tideillä

Tideillä is a Finnish word that translates to "tides" in English. It refers to the periodic rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun. These celestial bodies create bulges in the Earth's oceans, and as the Earth rotates, different locations experience these bulges as high tide and the areas between them as low tide.

The timing and height of tides vary depending on geographic location, the phase of the Moon, and the alignment of the Sun and Moon. In most coastal areas, there are two high tides and two low tides approximately every 24 hours and 50 minutes. This extra 50 minutes is due to the Moon's orbit around the Earth.

Tides are a significant factor in coastal ecosystems, influencing the distribution of marine life and the formation of intertidal zones. They also have practical implications for navigation, fishing, and coastal engineering. The study of tides is known as tidalography or tidal science. In Finnish culture, discussions about weather and the sea often include references to the state of the tides, especially in coastal communities.
