Trade route

Trade route is like a travelling road. People use it to travel between different parts of the world to buy and sell things. People carry things in big ships or over land in caravans. They sail or travel along these routes to get to places where they can buy and sell things. These items could be rare and valuable, like spices or jewelry, or everyday things like food. People have been using trade routes since ancient times to get what they needed!
