How do the tides work?

How do the tides work?

This term for our inquiry we are learning about space.  We have recently been focusing on the moon, Night and day and Tides. This is  a task that we did this week.  So as you can see this explanation is mostly talking about the tides.  Before we did this activity we watched a video and had to fill in the gaps from the video so it was like a memorization game.  It was really difficult to understand because it wasn't really loud and there was a lot of scientific words which made it more confusing to understand.

Here are some keywords from this writing: 

Centrifugal Force
Gravitational
The surface of the earth
Tides
Rotation
Buldge

I hope you enjoy my blog and I dare you to comment what you think I can improve.

Question of the Blog - What are you learning about?

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.
