Answer 1

The correct answer is Erosion.

Key Points

Geologic Erosion or "natural" erosion, is the action of the wind, water, ice and gravity in wearing away rock to form soil and shape the ground surface. Except for some stream and shore erosion, it is a relatively slow, continuous process that often goes unnoticed.

Additional Information

Accelerated Erosion is the speeding up of erosion due to human activity. Whenever we destroy the natural vegetation or alter the contour of the ground without providing some sort of surface protection, we greatly increase the rate of erosion.
Soil erosion is the process of detachment transportation and deposition of soil particles by wind, water or other phenomenon.
Water erosion is the process of detachment transportation and deposition of soil particles by water.

Weathering

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the earth.
Weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain, and waves.
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Thus, this weathering which leads to both the mechanical breakup of rocks and the chemical weathering of minerals contributes to soil formation.
Therefore, weathering leads to soil formation.

Metamorphosis

Metamorphosis is the process by which animals undergo rapid physical changes sometime after birth. Examples of metamorphosis include the process undergone by most insects and the transformation of tadpoles into frogs.

Sedimentation

Sedimentation is the process of allowing solid particles in suspension in water to settle out of the suspension under the effect of gravity.
The particles which settle down during sedimentation are called sediments.
This method is used for the separation of insoluble substances which are heavier than liquid or water.
In this process, heavier components of the mixture settle on the bottom on their own due to gravity.
