Q1. A sedimentary rock sample weighs 2500 kg and has a volume of 1.5 cubic meters. Calculate its density and identify which common sedimentary rock it most likely represents, given typical densities: Sandstone (2200-2600 kg/m³), Limestone (2300-2700 kg/m³), Shale (2400-2700 kg/m³).

  1. Density = 1666.7 kg/m³; likely Sandstone
  2. Density = 3750 kg/m³; likely Limestone
  3. Density = 1666.7 kg/m³; likely Shale
  4. Density = 1666.7 kg/m³; none of the above

Q2. Compare the durability of igneous stones with sedimentary stones for use in heavy construction projects.

  1. Igneous stones are generally less durable than sedimentary stones.
  2. Sedimentary stones have higher durability than igneous stones.
  3. Igneous stones are generally more durable and stronger than sedimentary stones.
  4. Both have equal durability regardless of type.

Q3. Which of the following is the primary basis for the classification of stones in civil engineering?

  1. Color and texture
  2. Origin and formation process
  3. Size and shape
  4. Weight and density

Q4. 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

Q5. 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

Q6. 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.

Q7. Which of the following is a common type of sedimentary rock used extensively in construction due to its durability and ease of shaping?

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

Q8. 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

Q9. 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

Q10. Compare the density of basalt and granite and identify which rock would generally be heavier for the same volume.

  1. Basalt is denser and heavier than granite.
  2. Granite is denser and heavier than basalt.
  3. Both have the same density and weight.
  4. Density varies too much to generalize between basalt and granite.

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. 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

Q13. What is the primary difference between intrusive and extrusive igneous rocks in terms of their formation?

  1. Intrusive rocks cool quickly on the Earth's surface, extrusive rocks cool slowly underground.
  2. Intrusive rocks cool slowly underground, extrusive rocks cool quickly on the Earth's surface.
  3. Both intrusive and extrusive rocks cool at the same rate but differ in mineral composition.
  4. Intrusive rocks are formed from sedimentation, extrusive rocks from lava flow.

Q14. 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.

Q15. Compare the porosity of sandstone and shale and explain how this difference affects their use in construction and water filtration.

  1. Sandstone has higher porosity than shale, making it better for water filtration but less stable for construction.
  2. Shale has higher porosity than sandstone, making it better for construction and water filtration.
  3. Both have similar porosity, so their uses in construction and filtration are identical.
  4. Sandstone has lower porosity than shale, making it less suitable for water filtration.
