Concept:Different means of transport have been used by humans throughout ages.Using these reduces the travel time considerably compared to walking.Tongas, chariots, boats etc are traditional means of transport.Cars, ships, and aeroplanes are all modern means of transport.Roadways are the most commonly used means of transport, especially for short-distance travel.Roads may be metalled or unmetalled.There is a dense network of roads in the plains.Roads can be built in deserts, high mountains, and forests too.Roads built underground are called subways or under paths.Railways are economical and faster.Steam engines have been replaced by diesel and electrical engines. The Railway network is well developed in plain areas.It is present in hilly terrain too, but not as much as in the plain areas.Airways ?It is the most expensive mode due to the high cost of fuel.It is vulnerable to bad weather like fog and storms.It is the only mode to reach even the most distant and remote locations which do not have a road/rail network.Explanation:Boat transport is a type of water transportation.It is used at places where people have to cross a river or lake.It also helps to transport goods from one place to another.States like Kashmir have a lot of lakes.Kerala is situated near the river.So, people use boats as a means of transport.Thus, in Kashmir and Kerala, we can see boar being used as a mode of transport.Additional InformationWaterwaysInland waterways?Navigable rivers and lakes are used as inland waterways.The Great Lakes in North America, the Ganga €œ Brahmaputra river system and the river Nile in Africa are some of the important inland waterways.Seaways?These are the oceanic routes and used for transporting goods from one country to another.These routes are connected with the ports.Some of the important ports in Asia are Mumbai and Singapore, New York, Los Angeles in North America, Rio de Jenario in South America, and Sydney in Australia.
