I think It is because of the Earth's Lithossphere and the Earth's Asthosphere

The ocean floor is the thinnest part.
They are actually part of the "same" theory. Seafloor spreading and subduction are the driving forces of continental drift. Pangaea was the Earth's only continent 4 billion years ago. Tectonic plates are small plates, while continent drift is several tectonic plates moving as a mass (continent). There are 21 large plates and dozens of smaller ones.
A tectonic plate would fit the above description.A tectonic (lithospheric) plate.A lithospheric (tectonic) plate.
The Caribbean tectonic plate is the plate upon which Aruba is located.Specifically, Aruba is an arid, sunny island in the southernmost Caribbean Sea. It is only 17 miles (27 kilometers) off the coast of the northern South American country of Venezuela. But the island is not part of that continent or of that continent's tectonic plate.
No, plate boundaries is part of the explanation of the Plate Tectonic theory:)
Sicily is part of Italy which is part of Europe, therefore it would be logical to say Sicily is on the European Continent. The island however sits on the African tectonic plate so geographically it is part of Africa.

The Canary Islands are on the African tectonic plate, and given their proximity to Africa they are most definitely in Africa.
continents are tectonic plates! so.... yes!
All tectonic plates are part of the Earth crust.
