Final answer:
The feature of the rock cycle is correctly described by 'b. Rocks change from one type to another'. This process is part of a continuous, dynamic cycle driven by geological forces, and it does not follow a specific order.
Step-by-step explanation:
The rock cycle describes the continuous and dynamic process by which rocks change from one type to another. The correct statement that describes a feature of the rock cycle is 'b. Rocks change from one type to another.' Igneous rocks, for instance, form when magma cools and solidifies, generating interlocking mineral crystals. Sedimentary rocks originate from the cementation of weathered rock debris or precipitation of minerals from water, forming layers over time. Metamorphic rocks arise from the transformation of existing rocks under the influence of high pressure and temperature, altering their mineralogical composition and texture without melting.
This transformation process is not linear or orderly; instead, it is complex and can happen in many different sequences depending on environmental conditions. The interactions between tectonic plate motions, temperature, pressure, and other geological forces drive the recycling of rocks, turning sediments into sedimentary rocks or exposing them to conditions that convert them into metamorphic or igneous rocks again.
