Final answer:
The dynamic equilibrium model of landforms refers to the concept that landforms are in a constant state of change and balance. It explains how external processes like weathering, erosion, and deposition shape the Earth's surface, while internal forces like tectonic activity and volcanic eruptions modify and reshape landforms.
Step-by-step explanation:
The dynamic equilibrium model of landforms refers to the concept that landforms are in a constant state of change and balance. It explains how external processes like weathering, erosion, and deposition shape the Earth's surface, while internal forces like tectonic activity and volcanic eruptions modify and reshape landforms. This model recognizes that landforms are not static but are dynamic features influenced by various forces.
