mining impact on environment
Where the pre-mining overburden contains sulfidic material that may produce acid drainage, the surface weathered (oxidised) zone is a valuable resource and care needs to be taken to ensure that this material does not end up being buried by sulfidic rock at the end of the mining operation.

soil zone subjected to climatic conditions
That is, the layer of the soil that can be affected by weather factors such as rain, snow, humidity, exposure to solar rays, etc. This layer can be as thick as 70 m in some cases.

weathered zone: near surface zone in which the exposed rock has been chemically or physically changed due to the action of rain, water, etc.

: Overburden is both rock or soil, and climatic conditions create the "weathered zone" .

zone of erosion caused by weather (by oxidation)
as the entire globe is exposed to climatic conditions, I suggest to use the term erosion

depth/area of rock affected by external forces
My understanding of this is that is is an area of rock that as been subjected to external forces that affect and weaken the structure of the rock e.g. frost, rain, wind, chemical processes. This takes place "in situ".
Soil is a product of such weathering - though soil can be affected by erosion, which is the removal of particles by external forces (water wind etc). Erosion is what happens when weathered particles are moved.
Weathered rock may have soil above it.
These are two separate processes - see the links below.
