Tide FAQs:


Q: Are tides the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth?

A: Yes.

Q: Are tides both gravitational and thermal in origin and are the dominant dynamics from about 80 to 120 kilometres?

A: Yes, and above which the molecular density becomes too low to support fluid behavior.

Q: Are tides known as tidal streams?

A: Yes.

Q: Is tide confirmed by measurement in 1840 by Captain Hewett?

A: Yes, and RN, from careful soundings in the North Sea.

Q: Are tides close to their narrow connections with the Atlantic Ocean?

A: Yes.

Q: Are tides primarily based on works of Muslim astronomers?

A: Yes, and which became available through Latin translation starting from the 12th century.

Q: Are tides commonly semi-diurnal , or diurnal?

A: Yes, The two high waters on a given day are typically not the same height; these are the higher high water and the lower high water in tide tables.

Q: Is tide found all along the south coast of the United Kingdom?

A: Yes, but its effect is most noticeable between the Isle of Wight and Portland because the M2 tide is lowest in this region.

Q: Is tide the perigean spring tide when both the sun and moon are closest to the Earth?

A: Yes.

Q: Is tide not necessarily when the Moon is nearest to zenith or nadir?

A: Yes, but the period of the forcing still determines the time between high tides.

Q: Were tides caused by the moon also reckoned that the moon is involved))?

A: Yes, Abu Ma'shar discussed the effects of wind and moon's phases relative to the sun on the tides.

Q: Are tides not twelve but 12?

A: Yes.

Q: Were tides caused by the general circulation of the heavens?

A: Yes.

Q: Are tides negligible at ground level and aviation altitudes?

A: Yes, and masked by weather's much more important effects.

Q: Are tides nearly in phase with the moon with a lag of about two hours?

A: Yes.

Q: Are tides a few days after new and full moon and are highest around the equinoxes?

A: Yes, though Pliny noted many relationships now regarded as fanciful.

Q: Were tides explained more precisely by the interaction of the Moon's and the sun's gravity?

A: Yes.

Q: Is tide the epoch?

A: Yes.

Q: Were tides caused by the Moon?

A: Yes.

Q: Is tide the hypothetical constituent "equilibrium tide" on a landless Earth measured at 0° longitude?

A: Yes, and the Greenwich meridian.

Q: Were tides caused by the moon?

A: Yes, although he believed that the interaction was mediated by the pneuma.

Q: Are tides the tidal forces exerted by galaxies on stars within them and satellite galaxies orbiting them?

A: Yes.

Q: Is tide rip tide?

A: Yes, and storm tide, hurricane tide, and black or red tides.

Q: Are tides usually the largest source of short-term sea-level fluctuations?

A: Yes, and sea levels are also subject to forces such as wind and barometric pressure changes, resulting in storm surges, especially in shallow seas and near coasts.
