During a field study examining Earth's external structure and surface processes, students observed solid bedrock disintegrating in situ into loose debris without immediate displacement. Which sphere of the Earth is primarily affected by this process, and how is this process correctly distinguished from mass wasting?
- Lithosphere; the process is weathering which occurs in situ, while mass wasting involves the gravity-driven downslope movement of rock material.Cevap
- BLithosphere; the process is weathering which involves downslope movement of debris, while mass wasting refers strictly to in situ disintegration of rock.
- CHydrosphere; the process is metamorphism caused by pressure, while mass wasting is the consolidation of marine sediments into sedimentary layers.
- DAtmosphere; the process is sedimentary deposition, while mass wasting is the thermal recrystallization of metamorphic rock layers.
Cevap
Lithosphere; the process is weathering which occurs in situ, while mass wasting involves the gravity-driven downslope movement of rock material.
The correct response identifies the lithosphere as the solid outer sphere where bedrock breaks down. It accurately states that weathering is an in situ process (disintegration on site without transportation), whereas mass wasting involves the movement of weathered material downslope under the direct influence of gravity.
