Question

the differences between these two maps resulted from the —
a missouri compromise
b treaty of ghent
c louisiana purchase
d adams-onís treaty
u.s. territory, 1800
u.s. territory, 1803

Explanation:

The maps show U.S. territory in 1800 and 1803. The Louisiana Purchase (1803) doubled the U.S. territory by acquiring land from France, which matches the territorial expansion seen. The Missouri Compromise (A) dealt with slavery in new states, the Treaty of Ghent (B) ended the War of 1812, and the Adams - Onís Treaty (D) involved Florida. So the Louisiana Purchase explains the territorial change.

Answer:

C. Louisiana Purchase
