What is the name of the phenomenon of wearing down of relief variations of the surface of the earth erosion?

Correct option is A

· Gradation refers to the process of leveling or wearing down relief variations on the Earth's surface. It is primarily driven by natural agents such as wind, water, glaciers, and waves through processes like erosion, transportation, and deposition.
· Gradation works toward achieving a balanced topography by removing material from elevated areas (degradation) and depositing it in lower regions (aggradation).
Key Points:
· Gradation Types: Includes degradation (erosion and removal of materials) and aggradation (deposition of materials).
· Role of Agents: Rivers, glaciers, wind, and waves actively contribute to this process.
· End Result: A smoother and more leveled landscape.
Additional Information:
· Eruptions: Refers to volcanic activities where molten rock or gases are expelled.
· Germinations: Describes the process of seed growth into a plant, unrelated to Earth's surface processes.
· Solidifications: Refers to the hardening of molten materials, such as magma cooling into rock.
