Gully – Landform created by running water and/or mass movement eroding sharply into soil; Guyot – Isolated, flat-topped underwater volcano mountain; Hanging valley – A tributary valley that meets the main valley above the valley floor; Headland – Landform extending into a body of water, often with significant height and drop
Llano Uplift - geologic map. The Llano Uplift can be considered an uplift by either its pattern on a geological or structural map of the top of the Precambrian rocks. It qualifies as an uplift because it consists of an extensive Precambrian basement high that is exposed by virtue of its surface lying significantly above in elevation the surface of surrounding Precambrian basement.

[2] It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to the west. [3]
A landform is a natural or anthropogenic [1] [2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain , and their arrangement in the landscape is known as topography .
