Question

3.what movement chased the land that is now the Baja peninsula to separate from Mexico?

Answer 1

Answer: The Baja California Peninsula was once a part of the North American Plate, the tectonic plate of which mainland Mexico remains a part. About 12 to 15 million years ago the East Pacific Rise began cutting into the margin of the North American Plate, initiating the separation of the peninsula from it. It ranges from 40 km (25 miles) at its narrowest to 320 km (199 miles) at its widest point and has approximately 3,000 km (1,864 miles) of coastline and approximately 65 islands. The total area of the Baja California Peninsula is 143,390 km2 (55,360 sq mi), roughly the same area as the country of Nepal.
