What are the various mobile and mighty exogenic geomorphic agents and what is the prime job they perform?
The various mobile and mighty exogenic geomorphic agents include running water, groundwater, glaciers, wind, and waves and currents. These are mobile mediums capable of acquiring and transporting earth materials.
The prime job performed by these geomorphic agents is to remove earth materials, transport them over slopes, and deposit them at lower levels. When these elements of nature become mobile due to gradients, they carry materials from higher levels to lower levels.
Gravity plays a crucial role as it activates all downslope movements and provides the directional force. Without gravity and gradients, there would be no mobility, and hence no erosion, transportation, and deposition would be possible.
Explanation
The answer identifies the exogenic geomorphic agents (running water, groundwater, glaciers, wind, waves and currents) as mentioned in the textbook context. The prime job of these agents—removal, transportation, and deposition of earth materials—is clearly stated. The role of gravity in enabling mobility through gradients is also highlighted from the context.
