Combining past and present tense

I get a bit confused when you can and can't combine the present and past tense. For example, look at the following sentence:

When the plane landed, I looked out the window because I wanted to see what Norway looks like.

Should it say, "Norway looks like" or "Norway looked like?" I ask because when I looked out the window, I didn't want to see what Norway looked like twenty years ago.

Any opinions?
