Statement 1 is correct:

Pedologists define soil as the surface material which has distinctive layers or horizons. Soil comprises minerals and organic particles, while subsoil or bedrock is composed wholly of minerals.

Statement 2 is correct:

Geomorphic factors such as relief, slope influence the formation of soils. On steeper slopes, the soil is thinner. On flat uplands areas, thick soil is formed.
