(iv) Give two examples of each of the following.
Ans:

  • Igneous rocks - Granite, Pumice
  • Metamorphic rocks - Marble, Slate
  • Sedimentary rocks - Shale, Sandstone

Q5: Long Answer Questions.

(i) How are igneous rocks formed?
Ans:
Igneous rocks are formed when magma cools down slowly and solidifies. Some igneous rocks are formed when the lava cools.

(ii) Briefly describe how sedimentary rocks are formed.
Ans: 
Sedimentary rocks are formed by the deposition of layers of rock particles one over the other. The little pieces of rocks are broken and worn away by wind and water.

(iii) Differentiate between shale and slate.
Ans: 

Shale

  • These rocks are sedimentary rocks made from the deposition of mud and clay.
  • It is used in making tiles and bricks.

Slate

  • These rocks are metamorphic rocks formed form the sedimentary rocks.
  • It is used to make blackboards and roof tiles.

(iv) How are metamorphic rocks formed?
Ans: 
Metamorphic rocks are formed from igneous and sedimentary rocks. When heat and pressure are applied to this rocks they change their form completely to form metamorphic rocks.

(v) Write one use each of any three minerals.
Ans: The various uses of minerals are -

  • Minerals such as potassium and nitrates make the soil fertile.
  • Minerals such as coal is used as fuel for cooking.
  • Gemstones are also minerals used to make jewellery.
    Example - Diamond and Ruby.

FAQs on Rocks And Minerals - 2 Class 2 Worksheet Science

1. What are the different types of rocks?
Ans. There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks are formed from solidified magma or lava, sedimentary rocks are formed from the accumulation of sediment, and metamorphic rocks are formed from the transformation of existing rocks under high heat and pressure.
2. How are rocks and minerals related?
Ans. Rocks are composed of minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. Rocks are made up of different combinations of minerals, and the type and arrangement of minerals within a rock determine its characteristics.
3. What is the rock cycle?
Ans. The rock cycle is a continuous process of formation, transformation, and erosion of rocks on Earth's surface. It involves the processes of weathering, erosion, deposition, compaction, and cementation. Rocks can be broken down into sediments, which can then be transported, deposited, and compacted to form sedimentary rocks. These rocks can then undergo metamorphism to become metamorphic rocks, and through melting and solidification, they can become igneous rocks again.
4. How can rocks be used as natural resources?
Ans. Rocks have various uses as natural resources. For example, igneous rocks like granite and basalt are commonly used as construction materials due to their strength and durability. Sedimentary rocks like limestone and sandstone are used in the construction industry and can also be sources of valuable minerals. Additionally, rocks such as coal and petroleum are important sources of energy.
5. How can we identify minerals and rocks?
Ans. Minerals can be identified based on their physical properties such as color, luster, hardness, cleavage, and specific gravity. Rocks, on the other hand, can be identified by their texture, mineral composition, and overall appearance. Geologists often use various tests and observations, including microscopic examination, chemical tests, and field observations, to identify minerals and rocks accurately.
