Northern Europe has a colder climate than the rest of Europe due to being farther north from the equator and closer to the poles than any other subregions. Most of the countries in Northern Europe are Marine West Coast or Humid Continental. The countries all border bodies of water, which causes all the places near the coast to have warmer winters and cooler summers. Norway has a lot of tall mountains which causes it have a colder climate. The Gulf Stream, an ocean current originating from the Gulf of Mexico, is the main thing that keeps Northern Europe warm in the winter. Northern Europe is also affected by other warm-water currents, Norwegian and North Atlantic currents, which transports warm water towards Europe. This causes Northern Europe to have less of a temperature variance than other places along the same line of latitude.
Most people in Northern Europe live near the coast as seen on the population density map. Most people also live in dense cities in apartments and highrises, like England. People live away from mountains and high altitudes due to it being cold and hard to settle on. Iceland is sparsely settled compared to the other countries in Northern Europe due to it having a Tundra climate. There is a variety of travel in Northern Europe due to the varying landscape. Countries have easy immigration between them due to how connected they are.
Most people live near cities near the coast.
