Final answer:
The transformation region involves showing the formation and movement of earth materials like igneous, sedimentary, or metamorphic rocks, and should consider the energy source such as solar radiation or geothermal energy.
Step-by-step explanation:
Rock Cycle and Plate Tectonics
The transformation region in the context of a rock cycle involves the transition of earth materials under the influence of various geological processes. When adding another transformation region to show where on Earth the material that became rock was formed, consider processes such as igneous activity, sedimentation, metamorphism, and erosion. The rock materials could be igneous, sedimentary, or metamorphic, depending on the history and environment of rock formation.
For instance, if the original region depicted the formation of sedimentary rocks, an additional region could illustrate the metamorphism of these rocks due to subduction leading to high pressure and temperature conditions supplied by Earth's interior energy. Processes like regional metamorphism would be relevant here, causing the formation of metamorphic rock from sedimentary parent material.
To demonstrate the movement of rock materials through the landscape, insert arrows showing the direction of rock transitions – for example, how sediment is transported by rivers and deposited in deltas, where it eventually forms sedimentary rock. This sediment could then be subducted along a plate boundary, buried and transformed into metamorphic rock through heat and pressure.
Labeling of transformation regions should highlight energy sources, identifying whether they're due to solar radiation causing weathering and erosion, or due to geothermal energy causing melting and metamorphism.
Geologic Map and Sedimentation
A geologic map would indicate different rock units, their contacts, as well as structural indications like strike and dip symbols. The map should have a proper scale, a north arrow, and should be colored based on rock types for easy identification.
