So, the United States wanted to find more opportunity in different places than where they were currently at. Of course they would go and expand their territory. United States pretty much bought out their way across the continent, with New Orleans and West Florida for $10 million as an example. They possibly fought for a bit of it, but most of it was bought out. :)
Why are areas along the west coast of California cooler than you would expect for their latitude? These areas are far from a large body of water. ... A cold ocean current travels along the coast.
