Question

which two oceans serve as political and geographic borders for the mainland united state (select all that apply.) great lakes atlantic ocean pacific ocean gulf of mexico

Explanation:

To determine the oceans that border the mainland United States, we analyze each option:

• Great Lakes: These are freshwater lakes, not an ocean, so they don't qualify.
• Atlantic Ocean: The mainland U.S. is bordered by the Atlantic Ocean on the east coast.
• Pacific Ocean: The mainland U.S. is bordered by the Pacific Ocean on the west coast.
• Gulf of Mexico: This is a gulf (a part of the ocean, but the question asks for oceans; also, while it borders the U.S., the two main oceanic borders for the mainland are Atlantic and Pacific).

So the correct options are the Atlantic Ocean and Pacific Ocean.

Answer:

B. Atlantic Ocean, C. Pacific Ocean
