Facies changes in sedimentary rocks refer to transitions in the characteristics of sedimentary deposits, such as grain size, composition, and sedimentary structures, over time and space. These changes can indicate shifts in environments of deposition, such as from a river to a delta or from shallow to deep marine settings. By studying facies changes, geologists can reconstruct the environmental conditions that existed in the past.

Can sedimentary rocks be formed at the bottom of lakes?
Yes, sedimentary rocks can be formed at the bottom of lakes through the accumulation and compression of deposited sediments over time. Processes like lithification can occur in lake environments, leading to the formation of sedimentary rocks such as shale or limestone.
what is the where it raines and rock gets smoother called?
sedimentary facies
What process changes metamorphic rocks into sedimentary rocks?
Subduction and high pressure.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Metamorphic rocks with the same mineral assemblages belong to the same?
metamorphic facies. This indicates that these rocks formed under similar pressure and temperature conditions despite coming from different locations.
What is the difference between facies in sedimentary rocks and facies in metamorphic rocks?
Most regional metamorphic rocks are formed in conditions within this range of geothermal gradients, passing through the greenschist facies to the amphibolites

What causes sedimentary rocks to change into hard rock?
weathering erosion transportation deposition compaction/cementation and lithification changes sediments to sedimentary rocks. High pressure and temperatures changes them to metamophic rocks
Can metamorphic rocks be formed from changes in igneous sedimentary or other metamorphic rocks?
yes
What rocks changes its form from once igneous or sedimentary?
metamorphic
What process changes metamorphic rocks into sedimentary rocks?
Subduction and high pressure.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
True or false sedimentary rock can be formed from changes in igneous rock but idneous rock cannot be formed changes in the sedimentary rock?
False Sedimetary rocks can be formed from changes in igneous rock, and igneous rock can be from changes in sedimentary rock.
What are three things that can change sedimentary rocks?
Heat and pressure from tectonic forces can metamorphose sedimentary rocks into metamorphic rocks. Weathering and erosion can break down sedimentary rocks into smaller particles or clasts. Hydrothermal fluids can alter the mineral composition of sedimentary rocks through processes like recrystallization.
What changes other types of rock to metamorphic?
Heating and pressurization changes igneous and sedimentary rocks into metamorphic rock.
