  1. Sand stone

  2. Lime stone

  3. Metamorphic rocks

  4. Igneous rocks

Show answer
Correct Option: D
Explanation:

Pumice is a light volcanic rock. It has a lot of pores in it. It is an igneous rock. The rock is light enough to float on water until it becomes waterlogged. Pumice is a very light rock which is used as body scrubber and to polish floor.

  1. soil

  2. cold

  3. magma

  4. fire

Show answer
Correct Option: D
Explanation:

The word 'igneous' is derived from a Latin word 'ignis' meaning fire. Igneous rocks are known as primary rocks as they are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

Primary rocks are the result of the following process ______________.

  1. Compression

  2. Metamorphism

  3. Solidification

  4. Sedimentation

Show answer
Correct Option: C
Explanation:

  • Generally, rocks can be divided into three major types based on the process of their formation
  • Igneous rocks are formed by the solidification and cooling of magma in volcanic areas, 
  • While sedimentary rocks are formed by a low-temperature accumulation of sediments in tectonic basins and topographical sinks. 
  • Metamorphic rocks on the other hand are formed by application of temperature and pressure on pre-existing rocks

  2. rocks

  3. forest

  4. none of these

Show answer
Correct Option: B
Explanation:

Weathering is the name given to the process by which rocks are broken down to form soils. Rocks and geological sediments are the main parent materials of soils (the materials from which soils have formed).
