Question

which term describes erosion?
○ creates small particles
○ hardens rock fragments
○ transports solid materials
○ dissolves rock components

Explanation:

Erosion in geology (a subfield of Natural Science, specifically Earth Science which can be under Geography or Environmental Sciences here) is the process of transporting solid materials (like sediments, rock fragments) from one place to another by agents like water, wind, ice, etc. "Creates small particles" is weathering (breakdown), "hardens rock fragments" is lithification, "dissolves rock components" is chemical weathering or dissolution. So the correct description for erosion is transporting solid materials.

Answer:

transports solid materials (the option with "transports solid materials")
