Which soil has the highest susceptibility to frosy heaving?Hide answer choices SiltCorrect answerIncorrect: ClaySandAll soils are the same

The soil that has the highest susceptibility to frost heaving is Silt.

Here's why:

1. Frost heaving is a natural process that occurs when the moisture in the soil freezes and expands, pushing the soil upwards.

2. The susceptibility of soil to frost heaving depends on its texture and the amount of moisture it can retain.

3. Silt has a fine texture and high moisture retention capacity, which makes it highly susceptible to frost heaving.

4. On the other hand, sand has a coarse texture and low moisture retention capacity, which makes it less susceptible to frost heaving.

5. Clay also has a fine texture, but its compact nature makes it less susceptible to frost heaving than silt.

6. Therefore, not all soils are the same when it comes to susceptibility to frost heaving.

So, the correct answer is Silt.
