If a sedimentary rock contains inclusions of metamorphic rock which rock is older?
The metamorphic rock would be older, because in the sedimentary rock's formation that is caused by collected sediment taking years to harden and turning into a rock, the metamorphic rock would have already been considered metamorphic when traces of it came into the sedimentary.
What else can I help you with?
A break that separates older metamorphic rocks form younger sedimentary rocks immediately above them is a type of unconformity called an?
a nonconformity
What is a sedimentary rock in which the older rocks unless disrupted are on the bottom?
This type of sedimentary rock is called a "nonconformity." It occurs when younger sedimentary layers are deposited on top of older, often deformed or eroded, igneous or metamorphic rocks. Nonconformities indicate a significant gap in the geological record due to erosion or tectonic activity.
What do geological principles tell you about inclusions?
Geological principles tell us that inclusions are pieces of older rock that are included within a younger rock formation. Inclusions are helpful in determining the relative ages of rock layers, as the rock containing the inclusion must be younger than the inclusion itself. Additionally, the types of inclusions present can provide information about the environment in which the rocks formed.
What two forces are needed to create a metamorphic rock?
Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.
Explain the relationship between the age of minerals within a clastic sedimentary rock and the timing of the rock's formation?
Since the rock particles, or clasts, that go into the making of a clastic sedimentary rock are weathered and eroded out of a previous rock formation, logically, they would be older than the cementious material that holds together the newly formed clastic sedimentary rock. Visualize a piece of San Onofre breccia, a sedimentary breccia rock which contains volcanic basalts, metamorphic schists, and other rocks, all cemented together as a sedimentary rock. The pieces of the rock are all from previously formed and eroded rocks. Although the sedimentary rock is fairly new, geologically speaking, the rock parts that make it up are much older.
How did metamorphic rocks get to be on the earth today?
Metamorphic rocks are older sedimentary, igneous, and metamorphic changed by pressure and temperature.

What is sedimentary rock in which the older rocksunless disruptedare on the bottom?
The type of sedimentary rock in which the older rocks, unless disrupted, are on the bottom is called a fossil-rich limestone. This rock contains fossil remains of prehistoric organisms.
What do geological principles tell about inclusions?
Geological principles tell you about inclusions that fragments are older than the rocks they are inside of.
How are inclusions used in the relative dating process?
The Law of Inclusions basically states that any rock (or mineral or fossil) that is entirely within another rock must be older than the rock containing it. The rock containing the inclusion formed around the already existing rock, thus preserving it inside. For example, a fossil bone found in limestone is necessarily older than the limestone surrounding it.
What is a sedimentary rock in which the older rocks unless disrupted are on the bottom?
This type of sedimentary rock is called a "nonconformity." It occurs when younger sedimentary layers are deposited on top of older, often deformed or eroded, igneous or metamorphic rocks. Nonconformities indicate a significant gap in the geological record due to erosion or tectonic activity.
What are the differences between the three types of Precambrian rocks found in Virginia?
In Virginia, the three types of Precambrian rocks are metamorphic, igneous, and sedimentary. Metamorphic rocks, such as gneisses and schists, formed through high-pressure and high-temperature processes, often from older rock types. Igneous rocks, like granites, originated from cooled magma and reflect volcanic activity in the region's geological history. Sedimentary rocks, although less common in the Precambrian, can include older sedimentary deposits that underwent lithification before being metamorphosed.
Is there a difference between metamorphic rocks and inclined sedimentary rocks?
Yes, the main difference is between a sedimentary rock and a metamorphic rock.A sedimentary rock is formed from various sizes of rock or rock particles (eroded from older rocks) that have been deposited by wind or water over time. The weight and pressure of subsequent deposits results in the squeezing out of water from the lowest depositional layers, and these layers may become cemented together as a solid rock.Metamorphic rocks are formed subjecting an existing rock (sedimentary or volcanic), to heat and or pressure after it was formed. This 'cooking' changes the rock, giving it new fabrics, textures and minerals.Both sedimentary and metamorphic rocks can be inclined with respect to their fabrics (beading in the case of sedimentary rocks), this is not a distinguishing feature.
What forces causes sedimentary rocks to be transformed into metamorphic rocks?
The essential force in the metamorphic rock formation is pressure. The needed changes are driven by changes in the physical measures of temperature and pressure. As these conditions change, alterations in the composition of the minerals and textures follow.
What do geological principles tell you about inclusions?
Geological principles tell us that inclusions are pieces of older rock that are included within a younger rock formation. Inclusions are helpful in determining the relative ages of rock layers, as the rock containing the inclusion must be younger than the inclusion itself.
