it is debatable where the land borders between the continents are located
& even whether they exist at all
but most people might agree that the land border between Africa & Asia
& the one between north & south America
are shorter than the one between Europe & Asia
& indeed there would not appear to be any others in the world than those 3
by any definition or opinion
as for which is the shorter one of these shorter two & thus the shortest of all
which you didnt ask but may have meant
certainly the isthmus of Panama is much narrower than the isthmus of Suez
& its canal much shorter too
so there is reason to conjecture that the border between the Americas
if any & wherever it may actually lie
is the shortest intercontinental land border in the world
No continents. Two countries: Canada and Mexico
none! There is ocean between the 2 continents
The shortest land border between continents is the border between Africa and Asia, which is mainly marked by the Suez Canal in Egypt, with a length of around 120 meters (394 feet). Another short land border between continents is the border between Europe and Asia, which is defined by the Ural River and the Ural Mountains in Russia, with a length of about 300 kilometers (186 miles).
There is no country that borders three continents.
there is no continent that borders both, there are two continents between the two oceans
there is no specific sea that or ocean that borders all continents
The shortest land border between two continents is found at the Isthmus of Suez in Egypt, which connects Africa and Asia. This narrow land bridge spans approximately 120 miles (193 kilometers) at its widest point. The Suez Canal, which runs through this isthmus, serves as a significant maritime route, but the land border itself is quite limited in length.
The Aradian Sea borders the continents of Asia and Africa. It lies between the Arabian Peninsula and the Indian subcontinent.
Neither Antarctica nor Australia have land borders with other continents. North America is connected to South America (separated at the surface by the Panama Canal). Europe, Asia, and Africa have land borders (Eurasia is actually one land mass, and the Suez Canal is actually entirely within Africa).

The shallow underwater plain that borders continents is called a continental shelf. It is an underwater extension of a continent's land mass that gradually slopes into the ocean. The continental shelf is an important area for marine biodiversity and is often rich in marine resources.
