  1. I guess because of a ridge caused by melting ice in ice age

  2. Southern limit of the Fennoscandian ice sheet about 11,500 years ago.

  3. You got your answer from others already, but check the shapes of lakes in finland, you can even see which direction the ice has moved. And the ring is the edge or melting point.

  4. Hi Sweden.

    Answer: Big ice. Give bump. Many lakes.
