Explanation:

The means of transportation have always been crucial for the shipping of goods, at how big of a distance can they be shipped, how quick, how much, at what cost, and what profit it will bring. There has always been efforts for the transportation to be improved and it constantly did. The industrial revolution made a big boom in it, as with it, the railroads and the steamboats were put in action. They made the transportation of goods much quicker, cheaper, and easier, plus on much bigger distance, which brought in a great economic development and the people were able to receive a variety of goods. As time was going, the trains were becoming much longer, more powerful and much faster, the planes were invented, as well as the big trucks, and the tankers, all being able to move goods around the globe or between regions very quickly and cheaply.
