The correct answer is B) fertile river valleys.
Glacial movement in Nordic nations did not cause fertile river valleys.
What Glacial movement caused in Nordic nations are jagged coastline, removed soil, leaving rocks behind, and thousands of lakes.
The coastline in the Nordic countries has been formed by the movement of the glaciers and the tremendous pressure that is exerted on the land. This pressure moves the land, move rocks, break the rocks and dragged into some parts of the land. The many minerals it shattered are dispersed in the water and get into the land. And of course, the formation of thousands of beautiful lakes that tons and tons of glaciers provided when they melt. That is why countries such as Norway have beautiful natural places and fjords that are protected by environmental agencies.
