Answer 1

The heavily eroded area south of the Columbia Plateau is called the Basin and Range Province. It is characterized by abundant horsts and grabens formed by extensional deformation and normal faults.

Step-by-step explanation:

The heavily eroded area south of the Columbia Plateau is called the Basin and Range Province. The Basin and Range Province is characterized by abundant horsts and grabens, which are a series of elevated plateaus and low basins formed by extensional deformation and normal faults.

This area extends from portions of Nevada, Oregon, and Idaho in the west to Utah and Colorado in the east. It was created as a result of erosion and plate tectonics, which over millions of years severely damaged the landforms. Thus, these features are a result of the movement along the San Andreas Fault and hypotheses ranging from mantle heating to movement on the fault.
