and rock from one
place to another.

from the weathering of
rock
what is it called when

away? (1 point)
○ weathering
○ erosion
○ raining
○ breaking

Explanation:

First Question (Weathering is...):

To determine the correct definition of weathering, we analyze each option:

• Option 1: "the breaking apart, wearing away, or dissolving of rock" matches the scientific definition of weathering, which involves the physical or chemical breakdown of rock.
• Option 2: "the scraping away of materials" is more related to abrasion (a type of erosion or mechanical weathering agent, but not the core definition of weathering).
• Option 3: "the moving of sediment and rock from one place to another" is erosion, not weathering.
• Option 4: "material that comes from the weathering of rock" describes sediment or regolith, not weathering itself.

We analyze the options based on geological concepts:

• Weathering: Breaks rock down (not movement).
• Erosion: The process of transporting weathered rock (sediment) from one location to another.
• Raining: A weather event, not related to transporting weathered rock.
• Breaking: Related to weathering (breaking rock), not transport.

Answer:

A. the breaking apart, wearing away, or dissolving of rock.

Second Question (What is it called when weathered rock is carried away?):
