FAQs on Class 5 Science - Rocks And Minerals - CBSE Worksheets - 2

1. What are the main types of rocks?
Ans. The main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma or lava, sedimentary rocks are created from the accumulation of sediments, and metamorphic rocks are formed when existing rocks undergo changes due to heat and pressure.
2. How do minerals differ from rocks?
Ans. Minerals are naturally occurring inorganic substances with a definite chemical composition and crystal structure, while rocks are composed of one or more minerals. For example, granite is a rock made up of quartz, feldspar, and mica, which are all minerals.
3. What is the rock cycle?
Ans. The rock cycle is a continuous process that describes how rocks change from one type to another over time. It includes processes such as weathering, erosion, sedimentation, and metamorphism, showing how igneous, sedimentary, and metamorphic rocks are interconnected.
4. How can we identify different minerals?
Ans. We can identify different minerals by examining their physical properties such as color, hardness, luster, streak, and cleavage. Using tools like a hardness scale, streak plate, or magnifying glass can help in accurately identifying minerals.
5. Why are rocks and minerals important to our everyday life?
Ans. Rocks and minerals are essential for many reasons. They are used in construction (like granite for countertops), in manufacturing (like quartz in electronics), and provide resources for energy (like coal and oil). Additionally, they play a critical role in earth processes and ecosystems.
