What objects will have a gravitational attraction to the Earth?

Which one has a greater gravitational pull on the Earth’s tides?

Why does the moon have a greater gravitational pull on the Earth’s tides?
Because it is closer to the Earth!

The moon exerts a gravitational pull on the Earth that causes the oceans to rise and fall.

The rise and fall of the oceans are called

The moon’s gravitational pull causes the oceans to bulge.
The moon’s gravitational pull causes the oceans to bulge.

Bulging of the oceans

The oceans bulge in two places:

Each of these bulges causes a high tide.Each of these bulges causes a high tide.

At the same time, low tides occur between the two bulges.
At the same time, low tides occur between the two bulges.

The high tides ALWAYS follow the moon.

How many high tides and low tides occur each day?
How many high tides and low tides occur each day?

How long does it take for the Earth to rotate once on its axis?

How many hours are there between a high tide and a low tide?
![Page 22: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/22.jpg)
How many hours are there between two high tides?
![Page 23: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/23.jpg)
At any given time of the day, how many high tides are there?
![Page 24: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/24.jpg)

High tides that are higher than normal are called
![Page 26: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/26.jpg)
This also means that the low tide is lower than normal during a spring tide.
![Page 27: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/27.jpg)
Spring Tides occur during the Full Moon and New Moon phases.
![Page 28: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/28.jpg)
The gravitational pull of the sun and moon are combined together since the sun, Earth and moon are in a straight line.
![Page 29: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/29.jpg)
High tides that are lower than usual are called
![Page 30: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/30.jpg)
This means that the high tides are not very high and the low tides are not very low.
![Page 31: Tides notes ppt](https://reader033.vdocuments.site/reader033/viewer/2022061205/548132c4b4af9fa1348b4786/html5/thumbnails/31.jpg)
Neap Tides occur during the First and Last Quarter Moon phases.

This means that the moon’s gravitational pull is partially cancelled out by the sun’s gravitational pull.
