The tide in Lake Michigan is described as 1.3 to 3.8 cm (0.5 to 1.5 in) [79] or 4.4 cm (1 + 3 ⁄ 4 in). [80] This is so small that other larger effects completely mask any tide, and as such these lakes are considered non-tidal.
However the effect is still enough to partly explain why tides along a coast lying behind a continental shelf are often higher than at offshore islands in the deep ocean (one of the additional partial explanations being Green's law). Resonances also generate strong tidal currents and it is the turbulence caused by the currents which is ...
This means that most atmospheric tides have periods of oscillation related to the 24-hour length of the solar day whereas ocean tides have periods of oscillation related both to the solar day as well as to the longer tidal lunar day (time between successive lunar transits) of about 24 hours 51 minutes.

Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
The tides received relatively little attention in the civilizations around the Mediterranean Sea, as the tides there are relatively small, and the areas that experience tides do so unreliably. [3] [4] [5] A number of theories were advanced, however, from comparing the movements to breathing or blood flow to theories involving whirlpools or ...
Body tides also exist in other astronomical objects, such as planets and moons. In Earth's moon, body tides "vary by about ±0.1 m each month." [11] It plays a key role in long-term dynamics of planetary systems. For example, it is due to body tides in the Moon that it is captured into the 1:1 spin-orbit resonance and is always showing us one side.
How time changes can affect your body: Can time change trigger depression? The return to standard time means we see less sunshine during our day. The loss of natural light can cause a decline in ...
