Explanation:

Statement 1: This refers to the mineral material, or organic material from which the soil is formed. Soils will carry the characteristics of its parent material such as color, texture, structure, mineral composition and so on.
Statement 2: Temperature and precipitation influence the speed of weathering of parent materials and thus soil properties such as mineral composition and organic matter content. Temperature directly influences the speed of chemical reactions. The warmer the temperature, the faster reactions occur.
Statement 3: The steepness of the slope affects the amount of deposition or erosion of soil material. A soil that is level is the most developed as there is no loss or gain of material to slow the soil forming process. The aspect of the slope affects the amount of water that moves through the soil.
