Part A : changing climate in western nebraska stabilized ancient dunes such as, sand hills by -

Grass now grows on Sand hills, stabilizing them.

A significant number of the plants of the Sandhills are sand-tolerant species from short-grass, blended grass, and tallgrass prairies; plants from every one of the three of these can be found inside the biological system.

Better land the executives and touching practices by the farmers of the district have prompted less disintegration after some time, which has kept the characteristic scene of the region for the most part unblemished.

Part C : The forces that affected the crust -

Tensional forces are acting on the crust.

Extensional forces in the crust results normal fault or gravity fault where hanging wall moves downward with respect to the footwall. One of the most widely recognized structures brought about by normal faults are grabens and horsts. The structures are the result of a several normal faults framing in nearness and dunking in inverse ways. This prompts the subsidence of a hanging wall (graben) between two foot walls (horst).
