You would probably expect a place that is farther north to be colder, but take a look at both teams' stadiums in the winter.
|The US National Team playing in Denver in winter.|
|Southampton playing in England on January 1, in the middle of winter.|
Why the difference? Why is it so much warmer in England where it's so much farther north? The grass is green! Shouldn't it be freezing there too?
Take a look at these two maps. What do you notice about where these two stadiums are compared to oceans? How do oceans affect the weather?
