The property of clayey soil that prevents it from supporting thick vegetation is its?
- composition of chemically weathered granite rocks
- inability to retain much water
-
tendency of becoming waterlogged
- porosity and low water retention ability
The correct answer is: C
Explanation
Clayey soil is a type of soil that is characterized by small particle size and high capacity for holding water. This property makes it prone to becoming waterlogged, especially during heavy rains. When soil is waterlogged, the water fills up all the air spaces between the soil particles, leaving no room for air. This lack of air can suffocate the roots of plants and can cause them to rot, making it difficult for thick vegetation to grow. Therefore, the property of clayey soil that prevents it from supporting thick vegetation is its tendency to become waterlogged.
