Test: Building Material & Construction - 1 - Question 15

Gneiss is obtained from

Detailed Solution for Test: Building Material & Construction - 1 - Question 15

Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.

Gneiss usually forms by regional metamorphism at convergent plate boundaries. It is a high-grade metamorphic rock in which mineral grains recrystallized under intense heat and pressure. This alteration increased the size of the mineral grains and segregated them into bands, a transformation which made the rock and its minerals more stable in their metamorphic environment.

Test: Building Material & Construction - 1 - Question 20

Which of the following is a sedimentary rock?

Detailed Solution for Test: Building Material & Construction - 1 - Question 20

The earth's crust is made up of various types of rocks, differing from one another in texture, structure, colour, permeability, mode of occurrence, and degree of resistance to denudation.

Generally speaking, all rocks may be classified into three major groups:

  • Igneous Rocks,
  • Sedimentary Rocks,
  • Metamorphic Rocks.

1. Igneous Rocks:

  • Igneous rocks are formed by the cooling and solidification of molten rock (magma) from beneath the earth's crust.
  • Example: Granite, Gabbro, Basalt, etc.

2. Sedimentary Rocks:

  • Sedimentary rocks are formed by the process of weathering and cementation or precipitation on the Earth's surface. 
  • Example: Sandstones, Kankar, shales, limestones, Mudstones, laterite, etc

3. Metamorphic Rocks:

  • Formed when rocks are subjected to high heat, high-pressure changes inside the Earth.
  • Example: Gneissoid, slate, schist, marble, quartzite, etc.
