Step 1:Let's solve this step by step:
Step 2:: Understand the Geological Processes
- Weathering is the breakdown of rocks at or near the Earth's surface - Erosion is the movement of weathered rock materials by wind, water, ice, or gravity - Deposition is the process of sediments being laid down in a new location
Step 3:: Analyze the Correct Sequence
The correct geological sequence is:
Step 4:
Weathering (breaking down of rock)
Step 5:
Erosion (transportation of weathered materials)
Step 6:
Deposition (settling of sediments)
Step 7:: Evaluate the Given Options
- Option A is incorrect because weathering comes after erosion - Option B is close, but the order of sediment is misplaced - Option C is incorrect because erosion occurs before sediment formation - Option D matches the correct geological process sequence
Step 8:: Detailed Process Explanation
\text{Rock} \xrightarrow{\text{Weathering}} \text{Broken Rock Fragments} \xrightarrow{\text{Erosion}} \text{Transported Sediments} \xrightarrow{\text{Deposition}} \text{Sedimentary Layer}
Final Answer
Rock → weathering → sediment → erosion → deposition
