The correct answer is: A. rock cycle
The rock cycle is a model that describes the natural processes which form various types of rocks. It is a closed system, meaning that the total amount of rock in the Earth’s crust does not change, but the types of rocks do change over time.
The rock cycle is driven by two main processes: igneous activity and weathering and erosion. Igneous activity occurs when magma or lava cools and solidifies to form igneous rocks. Weathering and erosion occur when rocks are broken down by physical and chemical processes, and the resulting sediments are transported by water, wind, or ice.
The rock cycle can be divided into three main stages: igneous, metamorphic, and sedimentary. Igneous rocks are formed when magma or lava cools and solidifies. Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. Sedimentary rocks are formed when sediments are deposited and compacted.
The rock cycle is a dynamic process, and the types of rocks present in any given area can change over time. For example, an igneous rock may be eroded and the resulting sediments may be deposited to form a sedimentary rock. The sedimentary rock may then be buried and subjected to heat and pressure to form a metamorphic rock. The metamorphic rock may then be melted to form magma, which may then cool and solidify to form an igneous rock.
The rock cycle is a fundamental concept in geology, and it is used to explain the origin and distribution of rocks on Earth.
Bowen’s reaction series is a model that describes the relative stability of minerals at different temperatures. It is not a model of the rock cycle.
Both the rock cycle and Bowen’s reaction series are important concepts in geology, but they are not the same thing.
