Question

What is the example of unconsolidated formulation?

• A. Limestone
• B. Shale
• C. Granite
• D. Sand

Hint:

• Unconsolidated formations consist of loose, unlithified sediments (e.g., sand, gravel, clay, silt).
• Consolidated rocks are formed when these sediments are compacted and cemented together (lithified).
• Limestone, Shale, Granite, and Sandstone are all examples of consolidated rocks.
• The question is problematic as it asks for an example of an unconsolidated formation but lists only consolidated rocks. Sandstone is formed from the consolidation of sand.

Answer 1

The Correct Option is D

The question asks for an example of an unconsolidated formulation.

1. Understanding the Concepts:

- Consolidated Formulation: Refers to rocks that are well-cemented and have strong inter-particle bonding, making them hard and resistant.
- Unconsolidated Formulation: Refers to loosely arranged particles that are not strongly bonded together, making them easily erodible or disaggregated.

2. Analyzing the Options:

- Limestone: Is a consolidated sedimentary rock composed primarily of calcium carbonate.
- Shale: Is a consolidated sedimentary rock formed from compressed mud and clay.
- Granite: Is a consolidated igneous rock with a crystalline structure.
- Sand: Consists of loosely arranged grains of minerals or rock fragments. These grains are not cemented together, making sand an unconsolidated material.

3. Determining the Unconsolidated Example:

Sand is the best example of an unconsolidated material from the given options because its particles are not cemented or strongly bound together.

Final Answer:

The example of an unconsolidated formulation is Sand.
