kolbaska11 [484]

Answer:

it is well i think it is The Market Revolution was characterized by a shift away from local or regional markets to national markets.

The agricultural explosion in the South and West and the textile boom in the North strengthened the economy in complementary ways.

Eli Whitney ‘s cotton gin and pioneering work with metal mechanical parts contributed greatly to industrialization.

Large-scale domestic manufacturing, concentrated in the North, decreased dependence on foreign imports and resulted in an increase in wage labor.

The power of the federal government grew under Henry Clay ‘s American System, which led to many improvements in the form of expanded roadways and canal systems.

The rapid development and westward expansion during the Market Revolution resulted in land speculation which caused economic boom and bust.
