Identify rock types from descriptions and images in this educational worksheet.

Let’s go step by step to solve each part of the worksheet.

Part 1: Identify the type of rock from the description

We have three choices:
- A. Igneous rock
- B. Sedimentary rock
- C. Metamorphic rock

Now, let’s match each description:

1) “This type of rocks is formed from sedimentary rocks that undergo pressure and heat.”
→ That’s metamorphic rock. When existing rocks (like sedimentary ones) get squeezed and heated deep underground, they change into metamorphic rocks.
✔ Answer: C

2) “This type of rocks is also called a fire rock.”
→ “Fire rock” means it comes from fire or heat — that’s igneous rock, which forms from cooled magma or lava.
✔ Answer: A

3) “This type of rocks is formed from the sediments.”
→ Sediments are tiny pieces of rock or sand that settle and harden over time → that makes sedimentary rock.
✔ Answer: B

4) “This type of rocks is mostly found on the surface of the Earth.”
→ Most rocks you see on the surface (like in rivers, deserts, beaches) are made from layers of sediment → sedimentary rock.
✔ Answer: B

5) “This type of rocks is formed from molten magma.”
→ Molten magma cools and becomes solid → that’s how igneous rock forms.
✔ Answer: A

Part 2: Fill in the type of the following rocks

We need to classify each named rock as igneous, sedimentary, or metamorphic.

1) Sandstone → Made from sand grains stuck together → Sedimentary

2) Obsidian → Glassy black rock formed when lava cools very fast → Igneous

3) Marble → Formed when limestone gets heated and pressed → Metamorphic

4) Gypsum → Soft mineral rock often formed from evaporating water → Sedimentary

5) Granite → Hard, speckled rock formed from cooled magma underground → Igneous

6) Slate → Smooth, flat rock formed from shale under pressure → Metamorphic
