Explanations:
Kolkata, the capital city of West Bengal, is classified as an inland riverine port. This classification is based on its geographical location and the nature of its port facilities. To understand why Kolkata is an inland riverine port, it is essential to first define the different types of ports and their characteristics.
A tidal port is one that is directly connected to the sea and is influenced by the tides. Examples of tidal ports include Mumbai and Chennai. These ports experience regular tidal changes that affect the water level and the navigation of ships. However, Kolkata is not directly connected to the sea; it is located on the Hooghly River, which is a distributary of the Ganges. The Hooghly River is not influenced by the tides in the same way as the sea, which is why Kolkata is not a tidal port.
A natural port is one that is formed naturally by the sea, often with a natural harbor or bay. Examples of natural ports include Sydney and Rio de Janeiro. These ports are typically formed by the natural topography of the coastline and are not constructed by humans. Kolkata, however, is not a natural port because it is not formed by the sea. It is located inland and is primarily a riverine port.
An artificial port is one that is constructed by humans, often with significant infrastructure such as breakwaters, jetties, and docks. Examples of artificial ports include Rotterdam and Singapore. While Kolkata has significant infrastructure, it is not classified as an artificial port because it is primarily a riverine port. The term "artificial" implies that the port is entirely constructed by humans, which is not the case for Kolkata.
An inland riverine port is one that is located on a river and is not directly connected to the sea. Examples of inland riverine ports include Pittsburgh and St. Louis. These ports are typically located on major rivers and are used for the transportation of goods and people. Kolkata is an inland riverine port because it is located on the Hooghly River, which is a distributary of the Ganges. The Hooghly River is navigable and allows for the transportation of goods to and from Kolkata.
In conclusion, Kolkata is classified as an inland riverine port because it is located on the Hooghly River and is not directly connected to the sea. This classification is based on its geographical location and the nature of its port facilities. Understanding the different types of ports and their characteristics is essential for correctly classifying ports like Kolkata.
