Final answer:
Aeolian processes are external geomorphic processes driven by wind, not internal. They shape landforms by eroding and depositing sediments, while internal processes, like tectonic forces, form mountains and valleys.
Step-by-step explanation:
Aeolian processes, which involve the wind's ability to shape the Earth's surface through erosion and deposition, are not a subdivision of internal geomorphic processes. Instead, they are categorized as external geomorphic processes, as they depend on atmospheric movements that exist outside of the Earth’s interior. Aeolian processes play a crucial role in shaping various landforms, such as sand dunes, and are also responsible for the transporting of fragments and sediments across different environments.
Internal geomorphic processes, on the other hand, include tectonic forces, which create mountains and valleys through the movement of the Earth's crust, and volcanic activities that can erupt and build new landforms. Erosion and soil-building processes are influenced by a combination of internal and external forces, shaping the earth's surface and affecting the lithosphere, atmosphere, hydrosphere, and biosphere.
The geo-mechanic phenomena associated with aeolian activities illustrate the dynamic interaction between the Earth’s surface and the atmosphere, which is pivotal for understanding how various physical processes influence different regions and the development of various landforms. Additionally, human activities may modify these processes through the influences of culture and technology.
