What are the four means of transportation?

Ans. The four major means of transportation are roadways, railways, airways, and waterways. Roadways are the most common and provide door-to-door service, making them very convenient for short distances. Railways are suitable for transporting large numbers of people and heavy goods over long distances at a relatively low cost. Airways are the fastest mode of transport and are mainly used for long-distance travel and urgent deliveries, although they are expensive. Waterways, including rivers and seas, are the cheapest mode for transporting bulky goods but are slower compared to others. Each mode has its own advantages and is used based on need, distance, and cost.
