Soil Formation - an overview | ScienceDirect Topics

Soil formation is a process strongly driven by the boundary conditions for the soil system. One of the key conditions (e.g., initial state in eqn [1]) is the physical configuration of the landscape, which dictates the nature of the 'geomorphic surface': the atmosphere/land boundary.From a physical perspective, landscapes can be stable, erosional, or depositional.

The Factors That Control Metamorphic Processes

The main factors that control metamorphic processes are: The mineral composition of the parent rock. The temperature at which metamorphism takes place. The amount and type (direction) of pressure during metamorphism. The amount and type of fluid (mostly water) that is present during metamorphism. The amount of time available for metamorphism.

How Are Minerals Formed? | Sciencing

All rocks are formed from a combination of minerals. You can identify a rock's type, along with characteristics that contributed to its formation, from its mineral composition. Minerals provide a basic reference for geologists to study the Earth's crust and are separated into categories based on their mineral composition and structure.
