Q1. A stone sample weighs 2400 kg and occupies a volume of 1 cubic meter. Based on this density, classify the stone type most likely represented.

  1. Lightweight sedimentary stone
  2. Heavy igneous stone
  3. Light metamorphic stone
  4. Artificial stone

Q2. Compare the characteristics of sedimentary and igneous rocks and select the correct statement.

  1. Sedimentary rocks are formed by cooling of magma; igneous rocks by deposition of sediments.
  2. Igneous rocks often contain fossils; sedimentary rocks do not.
  3. Sedimentary rocks are typically layered; igneous rocks are usually crystalline and non-layered.
  4. Both sedimentary and igneous rocks form under high pressure and temperature conditions.

Q3. A sample of a metamorphic rock weighs 2500 kg and has a volume of 1.25 m³. Calculate its density and identify which common metamorphic rock it most likely represents, given typical densities: Slate (2700 kg/m³), Marble (2800 kg/m³), Quartzite (2650 kg/m³), Schist (2600 kg/m³).

  1. 2000 kg/m³, likely Schist
  2. 2500 kg/m³, likely Slate
  3. 2000 kg/m³, likely Marble
  4. 2000 kg/m³, likely none of the above

Q4. Compare the uses of marble and quartzite in civil engineering. Which statement correctly distinguishes their typical applications?

  1. Marble is preferred for structural foundations, quartzite for decorative flooring.
  2. Quartzite is used for heavy-duty paving, marble mainly for ornamental purposes.
  3. Both marble and quartzite are equally used for roofing tiles.
  4. Marble is more resistant to acids than quartzite, making it better for industrial floors.

Q5. Which of the following is the primary basis for the classification of rocks?

  1. Color of the rock
  2. Origin and formation process
  3. Size of the rock fragments
  4. Location where the rock is found

Q6. What is the primary process responsible for the formation of sedimentary rocks?

  1. Cooling and solidification of magma
  2. Deposition, compaction, and cementation of sediments
  3. Metamorphism due to heat and pressure
  4. Crystallization from evaporating solutions

Q7. A rock sample weighs 2500 grams and has a volume of 1000 cm³. If this rock is classified as igneous, what is its density in g/cm³?

  1. 0.4 g/cm³
  2. 2.5 g/cm³
  3. 25 g/cm³
  4. 250 g/cm³

Q8. What is the primary geological process responsible for the formation of metamorphic rocks?

  1. Cooling and solidification of magma
  2. Deposition of sediments
  3. Heat and pressure altering existing rocks
  4. Weathering and erosion

Q9. A construction engineer needs a stone that has undergone intense heat and pressure but was originally sedimentary. Which classification of stone should he select?

  1. Igneous stone
  2. Metamorphic stone
  3. Sedimentary stone
  4. Artificial stone

Q10. A construction project requires a sedimentary rock that is highly resistant to weathering and has a fine-grained texture. Which rock type should be recommended?

  1. Shale
  2. Limestone
  3. Conglomerate
  4. Sandstone

Q11. Which of the following is a common type of metamorphic rock used extensively in construction due to its durability and aesthetic appeal?

  1. Granite
  2. Marble
  3. Sandstone
  4. Limestone

Q12. Identify the type of stone formed by the cooling and solidification of molten magma.

  1. Sedimentary stone
  2. Metamorphic stone
  3. Igneous stone
  4. Limestone

Q13. Identify the type of rock formed by the cooling and solidification of magma or lava.

  1. Sedimentary rock
  2. Metamorphic rock
  3. Igneous rock
  4. Fossiliferous rock

Q14. Which of the following is a common intrusive igneous rock widely used as a building stone due to its durability and aesthetic appeal?

  1. Basalt
  2. Granite
  3. Pumice
  4. Obsidian

Q15. A construction project requires a stone that is resistant to weathering and has a fine-grained texture. Which metamorphic rock would be most suitable?
