Which ocean borders Mexico to the west?

The Pacific Ocean borders Mexico to the west, making it the correct answer. This ocean is the largest and deepest in the world, stretching from the Arctic region in the north to the Antarctic region in the south, and it plays a significant role in the climate and ecosystems of Mexico's western coastline. The Pacific is known for its diverse marine life and is an important area for trade and shipping for countries along its coasts, including Mexico.

The other options do not correctly represent the ocean that borders Mexico's western shore. The Indian Ocean is located to the southeast of Africa and did not affect Mexico, while the Arctic Ocean is situated north of Canada and Russia, far removed from Mexico. The Atlantic Ocean, which lies to the east of Mexico, does not border its western coastline at all. Thus, the identification of the Pacific Ocean as the body of water to the west is accurate and essential for understanding Mexico's geography.
