The wheel was an important invention for transportation

Before the wheel, people had to carry everything by hand or use animals to pull heavy loads. The wheel changed this by allowing people to build carts and chariots that could carry more weight with less effort. This was a game-changer for transportation. It meant that people could travel longer distances and move more goods. Over time, the wheel was used for all sorts of vehicles, from simple carts to complex machines. The impact of the wheel on transportation can be seen in how it spread across the world. As people traveled and traded, they shared the idea of the wheel with others, who then used it in their own ways.
