- The stratification of parent material (heterogeneous parent material) has a more complex influence on the material migration and soil fertility, compared with homogeneous parent material. The stratification of parent material will be inherited to soil.
- Which of the following statements are correct? A: The greater the modulus, the stiffer the material. B: The stiffer the material, the higher the resistance of the material to deformation.
