Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Granite is a light-colored igneous rock. It is composed mainly of quartz and feldspar with a little amount of mica, amphiboles and other minerals. Granite is the world's toughest substance and is used in jewelry making. As few granites are rare and extremely beautiful. They are used as gemstones. Example of granite- blue tint found in the Himalayas etc.

Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  2. cold

  3. magma

  4. fire
Reveal answer Fill a bubble to check yourself
D Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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

Indian plateaus are made up of _______.

  1. igneous rocks

  2. metamorphic rocks

  3. shale

  4. sedimentary rocks
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Indian plateaus are made up of igneous rocks. Igneous rocks formed by the cooling and solidifying of molten materials . It can form beneath the Earth's surface , or at its surface, as lava. Deccan trap form the centre of igneous rocks in india.They cover almost all part of Maharashtra, a part of Gujrat, Madhya Pradesh , Andra Pradesh marginally. They are formed by sub - aerial volcanic activity associated with continental deviation in this part of earth in mesozoic era.
