vi. Similar to the steam boat, the steam train increased the ability of industrialized nations to transport people and goods long distances. This allowed industrialized nations, such as Britain, to move goods to market and to transport raw materials into factories.
The first mode of transportation was created in the effort to traverse water: boats. Those who colonized Australia roughly 60,000–40,000 years ago have been credited as the first people to cross the sea, though there is some evidence that seafaring trips were carried out as far back as 900,000 years ago.
