FAQs on Rocks and Minerals - 2 Class 2 Worksheet Science
| 1. What are the main types of rocks? |  |
Ans.The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma or lava, sedimentary rocks are made from particles and organic materials that have settled and compacted, and metamorphic rocks are formed when existing rocks are changed by heat and pressure.
| 2. How can you identify different minerals? | |
Ans.Different minerals can be identified by their physical properties such as color, hardness, luster, and streak. You can also use tests like the Mohs hardness scale to determine how hard a mineral is, and the streak test to see the color of the powder left behind when the mineral is scratched.
| 3. Why are rocks and minerals important to us? | |
Ans.Rocks and minerals are important because they are used in everyday products, including building materials, jewelry, and electronics. They also play a crucial role in our environment and natural processes, such as soil formation and water filtration.
| 4. What is the rock cycle? | |
Ans.The rock cycle is the continuous process through which rocks are formed, broken down, and transformed into other types of rocks. It includes processes like melting, cooling, eroding, and compacting, allowing rocks to change from one type to another over time.
| 5. How do fossils form in sedimentary rocks? | |
Ans.Fossils form in sedimentary rocks when plants or animals are buried by layers of sediment. Over time, the pressure from the layers compresses the organic material, and minerals can replace it, creating a fossilized record of the organism.
