Final answer:
The Hebgen Lake earthquake in 1959 greatly impacted Yellowstone National Park, causing significant landslides and ecological changes due to the region's geological activity.
Step-by-step explanation:
The earthquake larger than magnitude 7 that occurred near Hebgen Lake in 1959 greatly affected Yellowstone National Park. This earthquake resulted in significant landslides and altered the landscapes and ecosystems within its impact area.
Considering the seismic activity and the presence of the Yellowstone Hotspot, it's clear that Yellowstone is a geologically active region, characterized by earthquakes, geysers, and hot springs.
This is linked to the movement of the North American plate over the Yellowstone hotspot, contributing to the park's unique geological features.
