Innovations I’m not 100% sure but I do think that’s is right
The frequency and speed of the wind
The energy of the waves hitting the shore
The hardness of the rock that makes up the shoreline
All of these will determine the shape and how fast a cliff is formed, such as the speed of the wind and water, as well as how hard a rock is, will shape how the rock looks like.
For example, if the wind and waves are traveling extremely quickly, and the rock is made of sand, the rock will break much quickly.
Hope this helps
The difference between a hypothesis and theory is that the hypothesis is based on observations, but doesn't have a solid proof, while the theory is based on solid proof.
So in order for the scientist to make his hypothesis into theory about the connection of all the Earth's oceans, will need to provide a proof. This proof can be obtained by a sea traveling that will be well documented, and during the travel the scientist to manage to sail through all of the Earth's oceans without having any physical obstacle between any of them.
