How did the scandinavians use technology to adapt to their environment?

Scandinavians used technology to clear areas to make it more livable, and to help them build up areas. For example:
Steel Axe: Was used for war, cutting down trees, etc.
As Scandinavians used to be "viking lands", they had boats purposely built to make it faster, allowing for faster raids and quick escapes. (i guess it can be used for fishing too lol)

With these, and others, including use of tactics, helped make Scandinavians adapt to their environment, (& strike terror in Europeans as they raid for things that they could not find or produce by themselves)

hope this helps
