How the tides work

This week we've been learning about how the Sun/Moon/Earth (SME) Affect our tides

How the tides work



The water in the oceans can move more easily than the land.
The gravitational attraction of the Sun and the Moon pull it towards the sides of the
Earth where the Sun and Moon are, and this causes a high tide.


The spin of the Earth, and the Earth being pulled away from the oceans towards the side where the Sun
and Moon are, causes a second high tide on the opposite side to the Sun and the Moon.
Between the two low tides, so as the Earth turns you get two high tides and two low tides every day.
As the Moon moves around the Earth, tides times change.


  • When the Sun, Moon and Earth line up we get a spring tide with a big difference between high and low tide.
  • When the Sun and Moon form a triangle with the Earth, then there is not much difference between high and low tide. This called a neap tide.


2 Kinds of Eclipse

  • Solar eclipse - Daytime, When the moon casts a shadow on the Earth, causing the sun to go dark, SME/New moon
Lunar eclipse - Night time, When the Earth casts a shadow on the Moon, the Moon to go dark. SEM/Full Moon
