The Rocky Mountains formed 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began sliding underneath the North American plate. ... Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks and valleys.
Most of the present physiographic regions of the Great Plains are a result of erosion in the last five million years. Widespread uplift to the west and in the Black Hills caused rivers draining these highlands to erode the landscape once again and the Great Plains were carved up.

Animals with chitinous exoskeletons and jointed appendages are classified as Arthropods.
<span>
Arthropods are invertebrates which have an exoskeleton (external skeleton) enveloped with cuticle of chitin, a segmented body, and paired jointed appendages (each segment contains a pair of appendages). The cuticle is a rigid structure (usually mineralised with calcium carbonate), so those animals must replace it periodically by moulting. Arthropods include insects, arachnids, myriapods, and crustaceans.</span>
Answer:
