2. Pericycle - Wikipedia

   en.wikipedia.org/wiki/Pericycle

   The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...

3. Rock cycle - Wikipedia

   en.wikipedia.org/wiki/Rock_cycle

   This diamond is a mineral from within an igneous or metamorphic rock that formed at high temperature and pressure. The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.

4. Rock (geology) - Wikipedia

   en.wikipedia.org/wiki/Rock_(geology)

   Anthropic rock is synthetic or restructured rock formed by human activity. Concrete is recognized as a human-made rock constituted of natural and processed rock and having been developed since Ancient Rome. [23] Rock can also be modified with other substances to develop new forms, such as epoxy granite. [24]

5. Formation of rocks - Wikipedia

   en.wikipedia.org/wiki/Formation_of_rocks

   The melt is made up of various components of pre-existing rocks which have been subjected to melting either at subduction zones or within the Earth's mantle. The melt is hot and so passes upward through cooler country rock. As it moves, it cools and various rock types will form through a process known as fractional crystallisation.

6. Parent material - Wikipedia

   en.wikipedia.org/wiki/Parent_material

   Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical ...

7. Cyclic sediments - Wikipedia

   en.wikipedia.org/wiki/Cyclic_sediments

   Cyclic sediments (also called rhythmic sediments [1]) are sequences of sedimentary rocks that are characterised by repetitive patterns of different rock types or facies within the sequence. Processes that generate sedimentary cyclicity can be either autocyclic or allocyclic, and can result in piles of sedimentary cycles hundreds or even ...

8. Carbonate–silicate cycle - Wikipedia

   en.wikipedia.org/wiki/Carbonate–silicate_cycle

   This figure describes the geological aspects and processes of the carbonate silicate cycle, within the long-term carbon cycle. The carbonate–silicate geochemical cycle, also known as the inorganic carbon cycle, describes the long-term transformation of silicate rocks to carbonate rocks by weathering and sedimentation, and the transformation of carbonate rocks back into silicate rocks by ...

9. Residuum (geology) - Wikipedia

   en.wikipedia.org/wiki/Residuum_(geology)

   Residuum is weathered rock that is not transported by erosion, contributing in time to the formation of soil.It is distinguished from other types of parent material in that it is composed solely of mineral, not organic, material, and it remains in place rather than being moved by the action of wind, water, or gravity.
