Task: Solve the problem and explain the solution
####
Step 1: Match the picture to the name of the rocks
We are given three images of rocks and need to match them with their correct names:
granite,
limestone, and
sandstone.
-
Image 1: This rock has a rough, porous texture with small grains visible. It is light in color and appears to be composed of fine particles. This matches the characteristics of
sandstone.
-
Image 2: This rock has a layered appearance with distinct horizontal bands. The surface looks smooth and compact. This matches the characteristics of
limestone.
-
Image 3: This rock has a coarse texture with large, visible crystals of different colors (e.g., white, black, and gray). This matches the characteristics of
granite.
So, the matching is:
- Image 1 →
sandstone
- Image 2 →
limestone
- Image 3 →
granite

Step 2: Fill in the blanks based on the image provided
The last part of the worksheet shows an image of a natural rock formation with an arch. We need to describe what we can see in the image and identify the formation.
-
Blank 2: "You can see rocks
forming an arch."
-
Blank 3: "You can see rocks
eroded by water."
-
Blank 4: "You can see rocks
shaped by wind and water over time."
-
Blank 5: "This is a
natural rock arch."
Final Answer:
1. Matching:
- Image 1 →
sandstone
- Image 2 →
limestone
- Image 3 →
granite
2. Blanks:
- You can see rocks
forming an arch.
- You can see rocks
eroded by water.
- You can see rocks
shaped by wind and water over time.
- This is a
natural rock arch.
Explanation:
-
Matching the rocks: Each rock type has distinct visual characteristics:
-
Sandstone is typically light-colored and composed of sand-sized grains, giving it a rough, porous texture.
-
Limestone often has a layered appearance and is smooth due to its composition of calcium carbonate.
-
Granite is coarse-grained with visible crystals of quartz, feldspar, and mica, making it appear speckled.
-
Describing the image: The image shows a natural rock arch, which is formed through erosion by water and wind over long periods. The arch is a result of differential weathering and erosion, where softer layers of rock are worn away faster than harder layers.
Final Boxed Answer:
\[
\boxed{
\text{1. Image 1 → sandstone, Image 2 → limestone, Image 3 → granite; 2. forming an arch, 3. eroded by water, 4. shaped by wind and water over time, 5. natural rock arch}
}
\]
