How Do The Tides Work?

How Do The Tides Work?

IALT: talk about what we learnt in Inquiry!

This term for inquiry our topic is based on Beyond Earth and space! In these past few weeks the Kia Manawanui syndicate have been having inquiry with Mrs Fepuleai! We have already learnt about the phases of the moon and we have recently been focusing on Tides and How they work! 

In a recent lesson Mrs Fepuleai gave us a video to watch and it was how the Moon, Earth and Sun control the tides! We also had to fill out blanks on a worksheet that was also given to us by Mrs Fepuleai!

Here are some key words:

Centrifugal Force

Gravitational

Bulge

Surface

Moon, Sun and Earth

Tides

Rotation

That is all for this blog! Below this is the Tidal Phenomenon worksheet that we had to fill out! I hope you guys enjoyed reading! Bye :)

Question of the blog: What is your inquiry topic for this term?

=================================

TIDAL PHENOMENON

What is a Tide?

A tide is not just the RISE and FALL of ocean water.  Tide is the movement of water caused by complex interactions between the GRAVITATIONAL and ROTATIONAL forces of the Earth, Moon and Sun.

The combined FORCES cause the oceans to BULGE out in the direction of the Moon.  As the Earth rotates around its AXIS, the bulge is directly in line with the MOON.  The Earth rotates a few times FASTER than the bulge, therefore the solid Earth moves TOWARDS the water bulge.  

Observing the tide from Earth, you might think that the water goes to the Earth’s SURFACE.  When in fact it’s the Earth’s SURFACE that meets the water bulge.

Now you know what tides are and how they occur.
