Answer 1

1. Rocks, Water, Weathering, Soil, Soil profile: Weathering is the odd one because it has to do with climate changes. The Rocks, Water, Soil, Soil profile is to do with land constituents

2. A-horizon, B-horizon, Bedrock, C-horizon : Bedrock is the out one odd. They are just bed pebbles. They are not the location.

3. Overgrazing, Deforestation, Grass cover, Forest fires, Soil erosion: Grass cover is the odd one, it is man made substance for ideal usage
