Answer: Rock are of three types– 1.Metamorphic rock 2. Igneous Rock 3.Sedimentary Rocks
Q-2: Define Soil.
Answer: Soil is a natural mixture of different constituents like organic matter,gases, liquids and minerals.
Q-3: What are the constituents of soil?
Answer: Organic mater,gases,liquids, minerals like quartz, silica and rock weathered compounds.
Q-4: Define Specific Gravity.
Answer: Specific gravity of soil is defined as the ratio of the unit weight of soil to the ratio of the unit weight of water at the same temperature.
Q-5: What is the dividing sieve between Coarse aggregate and Fine Aggregate?
Answer: 4.75 mm Sieve
Q-6: What is the Effective Size of soil?
Answer: The soil grain diameter that is 10% finer in particle size distribution curve is termed as effective size of the soil.
Q-7: Define Uniformity Co-efficient(Cu).
Answer: Uniformity Coefficient is defined as the ration of the particle diameter of 60% finer and 10% finer in the particle size distribution curve.
Q-8: Define Co-efficient of Gradation(Cc)
Q-9: What is Void Ratio?
Answer- Void Ratio is defined as the ration of volume of voids to the volume of soil mass in a soil sample.
Answer: Porosity (n) is defined as the ratio of volume of voids to the volume of soil mass in a soil sample.
Q-11: What is Degree of Saturation (S)?
Answer: Degree of saturation(S) is the ration of volume of water to the volume of voids.
Q-12: What is the relationship between void ratio and porosity?
Q-13: How would you calculate the moisture content of a soil mass?
Answer: Moisture content is defined as the ratio of weight of water to the weight of soil solids.
Q-14: What is unit weight of soil?
Answer: Unit weight is defined as the weight per unit Volume.
Q-16: What is Density?
Answer: Mass per unit volume is defined as density of soil mass.

Answer: Solid,semi-solid,plastic and liquid.
Q-19: What is Shrinkage Limit?
Answer: Shrinkage limit is the minimum water content at which the soil mass transfers its state from solid to semi-solid state.
Q-20: What is Plastic Limit?
Answer: Plastic limit is the minimum water content at which the soil mass changes its state from semi-solid to plastic state.
Q-21: What is Liquid Limit?
Answer: Liquid limit is the minimum water content at which the soil mass change its states from plastic limit to liquid limit.
