  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

None of the above


Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff.

Andesite is a fine-grained, extrusive igneous rock composed mainly of plagioclase with other minerals such as hornblende, pyroxene, and biotite.

Rocks like sandstone which allow water to seep through readily are called ______________.

  1. Permeable rocks

  2. Sedimentary rocks

  3. Metamorphic rocks

  4. Mushroom rocks
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Permeable rocks are the rocks having interconnected pores which allow the water to seep through them. Hence option A is correct.
  • Sedimentary rocks and metamorphic rocks are a  broad classification of rocks.
  • Mushroom rocks derive their name out of their shape.

When the lava inside the Earth solidifies, it results in the formation of _______________.

  1. sedimentary rocks

  2. plutonic rocks

  3. volcanic rocks

  4. metamorphic rocks
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • When the lava solidifies before reaching the surface, it gives rise to the rocks called plutonic rocks.
  • Volcanic rocks are formed when lava solidifies on the surface of the earth.
  • Sedimentary and metamorphic rocks are not directly related to lava.
  • Hence option B is the correct answer.

Stalactities and stalagmites are most common in ___________.

  1. limestone areas

  2. hard rock areas

  3. snow capped areas

  4. desert areas
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Stalactites and stalagmites are the depositional landforms of limestone areas. The calcareous deposits from dripping of water in dry caves are called dripstones. The columns of dripstones hanging from the cave ceiling are called stalactites while the calcareous columns of dripstones growing upward from the cave floor are known as stalagmites.

Which of the following is called 'Primary rocks'?

  1. Metamorphic rocks

  2. Sedimentary rocks

  3. Igneous rocks

  4. Stratified rocks
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Igneous rocks begin the rock cycle, and are therefore called primary rocks. Two major divisions include- volcanic or extrusive rocks that form when magma is ejected from the Earth's crust, and intrusive rocks, which are created below the surface.

The precious stones line sapphire, ruby, emerald and diamonds are found in ______________ rocks.

  1. chemical sedimentary rocks

  2. metamorphic rocks

  3. igneous rocks

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Precious stones like rubies, emeralds, and sapphires are typically found in metamorphic rocks, which form under high pressure and temperature conditions that allow for the growth of these crystals.
