Canal

A canal is a waterway made by humans. For many centuries, canals have been built as a way of transporting heavy goods in barges or boats. Canals often connect lakes, rivers, or oceans. The Panama Canal is a famous canal that connects the Atlantic Ocean with the Pacific Ocean. Many canals are reinforced with clay or concrete on the sides and have locks.
