CBSE Class 5 EVS Worksheet Rocks and Minerals Answers 1. Option D 2. Type of sedimentary rocks are 1. Shale: It is made up of solidified clay apart in thin layers. It is used in making bricks and cement. 2. Limestone: It is usually an organic sedimentary rock that is formed from the accumulation of shell, coral, algal, and faecal debris. It is used as a building material. 3. Option A 4. Option A Solution: Yes, volcanic rocks are more durable because they have a more resistant property coming from magma or lava.

5. Option B 6. Option D 7. Option C 8. Option B 9. Option A 10. The three main types of rock are sedimentary, metamorphic, and igneous. 1. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. So they are formed due to the accumulation of sediments and compression of lower layers over long periods of time. eg. shale 2. Igneous rocks are formed from melted rock that has cooled and solidified. eg. basalt. 3. Metamorphic rock- When sedimentary and igneous rocks are subjected to pressures so intense or heat so high that they are completely changed and Metamorphic rock is formed. Hence metamorphism does not melt the rocks but instead transforms them into denser, more compact rocks. eg. -marble 11. Option C 12. Option A 13. Option A 14. Option C 15. Option B 16. Option B 17. Option A 18. Types of metamorphic rocks are 1. Slate: It is formed from shale a sedimentary rock. It splits into flat layers. It is used in making brick and cement. 2. Gneiss: It is formed from granite. It has different kinds of minerals in it, giving it a striped or streaked look. It is used as building stone. 19. 1. The energy in coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests. 2. When these giant plants died, they formed layers at the bottom of the swamps. 3. Water and dirt began to pile up on top of the dead plant remains. 4. Over thousands of years pressure and heat would build up on top of the plant remains, undergoing chemical and physical changes and pushing out the oxygen, turning these into coal. 20. Option A
