The Baja California peninsula lies across a narrow gulf from mainland Mexico. Much of the mainland has high interior terrain between mountain belts, while Yucatán forms a broad low peninsula in the southeast. Northern dry landscapes differ from the wetter tropical south.
Baja California, the plateau, and Yucatán
Compare Baja California with Yucatán. Both are peninsulas, but their shapes, relief, and positions within the surrounding seas differ.

The Sonoran Desert extends across the US border. Tropical lowlands continue into Belize and Guatemala. Match a coast or regional mountain pattern before treating either desert or forest as evidence for a country.
