The Titanic sank because the watertight bulkheads were not tall enough to prevent water from spilling over the top. When the ship hit the iceberg, the force of the impact caused the iceberg to tear a series of holes along the side of the ship, allowing water to flood multiple compartments. As the water filled these compartments, it spilled over the top of the bulkheads, causing the ship to eventually sink. Additionally, the bulkheads were not sealed at the top, allowing water to flow from one compartment to another. **
