Question

What is the geographical name given to the narrow strip of land connecting two large land masses?
A) Island
B) Tombolo
C) Isthmus
D) Landbridge

Answer 1

Hint: A landmass, also known as a land mass, is a large area of land. The term is frequently used to describe lands surrounded by water, such as a continent or a large island. A landmass is a defined section of continental crust that extends above sea level in geology.

Complete answer:
Let us analyze the given options:
Option A) Island:Any piece of subcontinental land surrounded by water is referred to as an island or isle. Islets, skerries, cays, and keys are all names for very small islands, such as emergent land features on atolls. A river or lake island is known as an eyot or ait, and a small island off the coast is known as a holm. Chars are sedimentary islands in the Ganges delta.

Option B) Tombolo: A sandy isthmus is referred to as a tombolo. A tombolo, derived from the Italian tombolo, which means "pillow" or "cushion," and sometimes translated as "ayre," is a deposition landform in which an island is joined to the mainland by a narrow piece of land such as a spit or bar. Once connected, the island is referred to as a tied island.

Option C) Isthmus: The earth's surface is divided into two sections. The large landmasses are referred to as continents, and the vast bodies of water are referred to as ocean basins. An isthmus (plural: isthmuses or isthmi) is a narrow stretch of land that connects two larger areas separated by a body of water. A tombolo is an isthmus formed by a spit or bar, and a strait is the sea equivalent of an isthmus.

Canals are frequently constructed across isthmuses, where they may provide a particularly advantageous shortcut for marine transport. The Panama Canal, for example, connects the North Atlantic and Pacific Oceans by crossing the Isthmus of Panama; the Suez Canal connects the Mediterranean Sea and the Red Sea by cutting across the western side of the Sinai Peninsula and the Crinan Canal crosses the isthmus between Loch Crinan and Loch Gilp, which connects the Kintyre peninsula with the rest of Scotland.

Option D) Landbridge: Land bridge, any of several isthmuses that have connected the Earth's major land masses at various times, resulting in the spread of many plant and animal species to new areas.

Thus, the answer is option ‘C’ i.e, Isthmus.



Note: An isthmus connects two larger landmasses, whereas a peninsula is a land protrusion connected to a larger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g., the Panama Canal), resembling two peninsulas; however, canals are artificial features distinct from straits.
