The process that creates a rust-like appearance on rocks is chemical weathering.
The process that creates a rust-like appearance on rocks is called chemical weathering. To get the answer, we need to understand the different types of weathering processes.
Weathering refers to the breaking down or alteration of rocks and minerals at or near the Earth's surface. There are three main types of weathering: physical weathering, chemical weathering, and biological weathering.
Physical weathering, also known as mechanical weathering, involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. Examples of physical weathering processes include freeze-thaw cycles, thermal expansion and contraction, and abrasion by wind and water.
Chemical weathering, on the other hand, is the process by which rocks and minerals undergo chemical changes, leading to the formation of new substances. This type of weathering occurs when certain chemicals interact with the rock, causing its composition to change. One example of chemical weathering is the formation of rust on iron-rich rocks or minerals. The oxidation of iron in the presence of water and oxygen results in the reddish-brown coloration that resembles rust.
In this case, the correct response that creates a rust-like appearance on rocks is "chemical weathering."
