The effects of the invention of the steamboat included:
- Increased travel westward - The steamboat made it easier and faster to travel along rivers, facilitating westward expansion.
- Allowed cheap movement of goods - Steamboats reduced the cost of transporting goods, making trade and commerce more efficient.
The other options, such as slowing the relocation of Native Americans and expanding rights for African Americans, are not directly associated with the invention of the steamboat.
