1-d, 2-a, 3-f, 4-c, 5-e, 6-b, 7-g, 8-h, 9-i, 10-j
Section C:
- Rocks are made up of minerals.
- Granite, Pumice.
- Shale
- Calcite
- Igneous rocks.
- Skin scrubber, dental abrasive.
- Remains of dead plants or animals in rocks.
- Sandstone
- Limestone
- Used for making surgical blades.
Section D:
- Igneous rocks are formed by cooling and hardening of magma. Example: Granite.
- Sandstone is formed by cementing sand particles; used in building monuments like Red Fort.
- Magma is molten rock inside Earth; lava is molten rock on the surface.
- They contain fossils and are sources of fuels like coal and petroleum.
- Granite is coarse-grained, hard, light-coloured; used for buildings and flooring.
Section E:
- Sedimentary rocks are formed when wind, water, or glaciers carry sediments that settle in layers. Over time, pressure hardens them into rocks. They often contain fossils.
- Pumice is a volcanic rock with holes, making it very light. It floats on water and is used in scrubbing, polishing, and construction.
