The Moon's gravity is the primary driver of tides.

ACTION 25 POINTS! Make the noise of a wave coming in onto the beach!

Tides are essentially the rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun, along with the Earth's rotation.

The Sun also exerts gravitational influence, although to a lesser extent than the Moon.

As the Earth rotates, different locations pass through these bulges, experiencing high tides.

As the tide rushes in from the Humber, it funnels through the narrowing channel, creating a wave or bore that can surge upstream.

The tidal Trent area, from Gainsborough to the Humber (Near Hull), is a flood alert area, meaning flooding to low-lying land is possible.

25 POINT QUESTION! Gainsborough is known for a tidal bore called the "Trent Aegir" or "Trent Bore" that can surge upstream.

The tidal part of the Trent continues up to Cromwell Lock, which is about 3 miles (5km) below Newark.

RIDDLE 25 POINTS! Can run but never walks, Has a mouth and never talks, Has a head but never weeps, Has a bed but never sleeps. What am I?

The Moon's gravity pulls on the Earth's water, causing it to bulge out on the side closest to the Moon.

The areas between the bulges experience low tides.

The planet Saturn's gravity is the primary driver of tides.
