Canals: Human made channels constructed to allow passages of boats or ships to travel through water. They were invented between 1750 and 1900. Canals work by having different types of locks. When the boat is ready to leave, the boat is placed inside a gate lock and then water begins to pour into the gate and when the water level is the same as the water level ahead in the canal, the top gate opens, releasing the boat.
Positive effects: Canals made moving heavy objects a large distance easier and faster. Canals could move up to forty tons of weight.
Negative effects: Canals could freeze up during the winter, and the canal could dry up in the summer so the workers would have to fill the canal with water regularly, so this made transporting items difficult.
Today's version of a Canal: Today, many canals are being used to connect water ways together and for transporting. The Erie Canal serves as a boating service to connect the Hudson River to Lake Erie. Also, the Panama Canal has improved the amount of cargo shipped worldwide.
Essential Question: The impact that Canals had on the Northern states were that canals improved roads and railways to expand domestic trade, which resulted in greater wealth and larger population in the North. Also, manufacturing and machinery increased.
The impact that canals had on the Southern states were that transporting cash crops and items was much easier and faster and could be sold cheaper. Since the boats on the canal could carry more cargo, more items could be transported to the North to become manufactured.
