Answer:
The correct answer is D. National Parks are an invention of the United States that has spread around much of the world, as a way of protecting some of the finest parts of the world.
Explanation:
A national park is a park in which the protection of nature comes first, albeit almost always in alignment with human activities (in particular recreation, often also forestry, agriculture, hunting and fishing, sometimes mining) in and around the national park. The state usually recognizes the national significance of such a park and guarantees its protection. The term was coined in the US around 1870. Shortly thereafter the Yellowstone National Park was founded in a special area with geysers and bison among others. This park serves as an example for many other parks. Since then, hundreds of national parks have been established worldwide.

Sorry, I won't understand the question what you asked now.
I’m confused, 3 observations on what?
The features that result as a form of a glacier carving out rock and forms into the landscape over which it slides are called cirques. When a glacier moves it erodes the surface of the earth beneath it. In this process of erosion large boulders and very small pebbles all get caught up in the path of the glacier and move along with it. This moment causes deep depressions into the earth, changing the landscape. The deposition of rocks and silt from a melting glacier also changes the form of the land over which the glacier moves.
