Final answer:
Coastal accessibility and mountainous terrain dictate the pattern of settlement in Greenland.
Step-by-step explanation:
The pattern of settlement in Greenland is dictated by several factors, including coastal accessibility and mountainous terrain. Coastal areas provide access to transportation networks, fishing resources, and trading routes, making them preferable for settlement. Mountainous terrain, on the other hand, may limit the availability of arable land and make it more difficult to establish infrastructure.
While polar bear populations may impact settlement patterns to some extent, they are not the primary factor. Similarly, volcanic activity is not a significant influence on settlement patterns in Greenland.
