Problem Overview:
The task involves identifying the type of rock (Sedimentary, Igneous, or Metamorphic) for each image provided and matching it with its correct definition. The goal is to understand the characteristics of each type of rock.
---
Step-by-Step Solution:
####
1. Understanding the Definitions:
-
Sedimentary Rock: Formed by layers of sediments (such as sand, mud, or shells) that are compacted and cemented over time.
-
Igneous Rock: Formed when magma (molten rock beneath the Earth's surface) cools and hardens.
-
Metamorphic Rock: Formed when existing rocks are changed by heat and pressure, altering their mineral composition and structure.
####
2. Analyzing the Images:
#####
Image 1:
-
Appearance: Dark, porous rock with visible holes or vesicles.
-
Characteristics: This rock has a bubbly texture, which is typical of igneous rocks formed from lava cooling quickly on the Earth's surface. The rapid cooling traps gas bubbles, creating the porous appearance.
-
Conclusion: This is an
Igneous Rock.
#####
Image 2:
-
Appearance: Layered rock with distinct bands of different colors and textures.
-
Characteristics: The layered structure is a hallmark of sedimentary rocks, which form from the deposition of sediments (like sand, mud, or shells) that are later compacted and cemented together.
-
Conclusion: This is a
Sedimentary Rock.
#####
Image 3:
-
Appearance: Grainy rock with a mix of small particles and no clear layering.
-
Characteristics: This rock appears to have been subjected to high pressure and temperature, causing the grains to be tightly packed and altered in structure. This is characteristic of metamorphic rocks.
-
Conclusion: This is a
Metamorphic Rock.
####
3. Matching the Definitions:
-
Definition 1: "Rock formed by layers of sediments. Compacting and cementation."
-
Match: Sedimentary Rock (Image 2).
-
Definition 2: "Rock formed when magma cools and hardens."
-
Match: Igneous Rock (Image 1).
-
Definition 3: "When heat and pressure change a rock."
-
Match: Metamorphic Rock (Image 3).

Final Answer:
-
Image 1: Igneous Rock
-
Image 2: Sedimentary Rock
-
Image 3: Metamorphic Rock
-
Definitions Match:
- Sedimentary Rock: "Rock formed by layers of sediments. Compacting and cementation."
- Igneous Rock: "Rock formed when magma cools and hardens."
- Metamorphic Rock: "When heat and pressure change a rock."
Boxed Final Answer:
\[
\boxed{
\text{Image 1: Igneous Rock, Image 2: Sedimentary Rock, Image 3: Metamorphic Rock}
}
\]
