Section E: Short Answer Questions 

23.

Three types of rocks:

Igneous (e.g., Granite)
Sedimentary (e.g., Sandstone)
Metamorphic (e.g., Marble)

24.

Metamorphic rocks are rocks formed from existing rocks due to high heat and pressure.
Examples: Marble, Slate, Quartzite, Gneiss

25.

Metallic minerals: Minerals that yield metals.
Examples: Bauxite (Aluminium), Malachite (Copper)
Non-metallic minerals: Minerals that do not yield metals.
Examples: Salt, Mica, Gypsum, Feldspar

26.

Natural magnets are found in nature (e.g., Magnetite).
Man-made magnets are created by humans using materials like iron, nickel, and cobalt.

Section F: Long Answer Questions (4 marks each × 4 = 16 marks)

27.

Sedimentary rocks are formed by the compression of layers of sediments. These sediments include sand, minerals, and dead plant/animal remains that settle over time.
Examples:

Sandstone: Formed from sand grains.
Shale: Formed from hardened clay.

28.

Uses of rocks and minerals:

Building materials (roads, schools, houses)
Jewellery and decoration (gold, silver, gemstones)
Machines and tools (computers, cars)
Making glass (feldspar, limestone)

29.

Igneous rocks are formed from the solidification of molten rock (lava).

Granite: Cooled slowly under the Earth, hard and used in buildings.
Obsidian: Cooled rapidly, smooth and glassy, used in jewellery.

30.

Metamorphic rocks form when existing rocks are changed by heat and pressure.

Marble: From limestone, used in statues and buildings.
Gneiss: From granite, used in road construction and landscaping.
