Ship locks are special ways to help boats travel across different water levels. They can be found in many places around the world, like the Panama Canal and the Suez Canal. When a ship reaches a lock, it fills with water or empties to lift or lower the boat. This process is important for shipping goods and traveling. Watching a ship go through a lock is fascinating. It shows how people have built smart ways to connect rivers and lakes, making travel easier for everyone.
