It been said by my lecturer a few times.She said and always reminds us that solid is not soil but in soil there is solid.I didn't knew anything about soil until I learnt about this subject.She is a fun and dedicated lecturer that willing to teach all her students about soil,about Earth and about environment.
The basic of building structures that constructed by engineer need a fine base.To find the most suitable and fine, we need to understand the soil. In this course I've learnt that not all soil is suitable for building bases. If they did build on the wrong base, the building may collapsed in few moths after build and could cause a lot of fatalities.
Soil is made out of 3 component which is air,water and solid. There are also grade for each type of soil. Certain calculation and laboratory test need to be made for grading the soil sample given.
