Final answer:
The point is to understand more about local relief and the landscape.
Step-by-step explanation:
The point of describing Horseshoe Park in the Colorado Rockies and looking back at North America from a spacecraft in the context of the chapter 'Introduction to Landform Study' is to understand more about local relief and the landscape. Local relief refers to the difference in elevation between the highest and lowest points in a specific area. By examining specific examples like Horseshoe Park and viewing the continent from a spacecraft, students can gain a deeper understanding of how the landforms and topography vary across different regions of North America.
