उत्तर
The goal of this project is to collect different rock samples from various locations, identify their types, and classify them into their respective categories (igneous, sedimentary, and metamorphic).
- Collect Rock Samples:
- Visit different locations such as parks, riversides, beaches, mountains, or even construction sites where rocks are exposed.
- Collect a variety of rocks from these places. Take a note of the location where you collected each rock sample.
- Identify and Classify the Rocks:
- Igneous Rocks: Formed from the cooling and solidification of magma or lava. Example: Granite, Basalt.
- Sedimentary Rocks: Formed from the deposition and cementation of material. Example: Sandstone, Limestone.
- Metamorphic Rocks: Formed by the transformation of existing rocks under high heat and pressure. Example: Marble, Slate.
- Label and Document: Label each rock sample with its name and location where it was collected. Write down the type of rock (igneous, sedimentary, or metamorphic) and any observable characteristics like colour, texture, and hardness in a notebook.
- Create a Display or Report: You can arrange the rocks in a display box or create a project report with details about each rock type, where it was collected, and its geological significance.
Sample Rock Collection:
Here are a few examples of rock samples you might find and collect:
- Granite (Igneous): Found in mountain regions. It’s light-coloured with visible crystals of quartz and feldspar.

- Basalt (Igneous): Often found in volcanic areas. It’s dark-coloured and has a fine-grained texture.

- Sandstone (Sedimentary): Commonly found in deserts or riverbeds. It’s made of sand-sized particles, often yellow or red.

- Limestone (Sedimentary): Found in areas that were once underwater. It’s often pale and can contain fossils.

- Marble (Metamorphic): Usually found in mountainous regions, it’s a fine-grained rock that is often white but can have veins of other colours.

- Slate (Metamorphic): Found in regions with ancient mountains. It splits into thin layers and is usually dark grey or black.
