> Over two thirds of the Earth is covered in sea water!
> The oceans contain 97% of all water on Earth.
> There is enough salt in the sea to cover the land with a layer 153 metres thick.
> Tides make the sea level rise and fall, they are caused by the moon and the sun pulling the water. When the moon and the sun are in line they cause very high tides and very low tides. These are called Spring Tides. When they pull at right angles they cause lower high tides and higher low tides. These are called neap tides.
> There are five oceans: Pacific, Atlantic, Indian, Southern and Arctic.
