What else can I help you with?
In an undeformed sequence of rocks the youngest rocks are found?
On top of the sequence, or closest to the surface. This is due to the principle of superposition, which states that in a sequence of undeformed sedimentary rocks, the youngest rocks are on top while the oldest rocks are at the bottom.
Where can strata can be found sedimentary rock or igneous rock?
Strata can be found in sedimentary rocks, which form in layers over time as sediments accumulate and compact. Igneous rocks, which form from molten magma cooling and solidifying, do not typically have distinct layers or strata.
What is the densest rock basalt limestone marble or shale?
Basalt has the highest density of the rock types mentioned.
What process is responsible for compressing successive strata in the earth?
The process responsible for compressing successive strata in the earth is known as lithostatic pressure. This is the pressure exerted by the overlying rocks and sediments on the underlying layers, leading to compaction and consolidation of the strata.
Do sendimentary rocks have many layers?
Yes, sedimentary rocks are typically composed of multiple layers, or strata, that have accumulated over time through the deposition and compaction of sediments. These layers can provide important information about the Earth's history and past environmental conditions.

How do the sequence of sedimentary rocks in cratons differ from those in mountain belts?
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.
In general the law of superposition states that in an undeformed sequence of sedimentary rocks each layer is .?
older than the one above it
What is the position in which fossils and rocks are placed in strata?
sideways
What type of mountains are generally made up of undeformed rocks?
Generally, volcanic mountains are made up of undeformed rocks due to the solidification of volcanic lava and ash. These mountains form from the accumulation of volcanic material over time, without significant tectonic forces deforming the rock layers.
Which is older deep strata or shallow strata?
There is no absolute trend, since geological faults can thrust older rocks above younger ones, and whole sequences can be turned upside down. However, more often than not, for a single location deeper strata are older.
What states That I an undeformed sequence of sedimentary rocks each bed is older than the one above it?
The principle you're referring to is known as the Law of Superposition, which states that in an undeformed sequence of sedimentary rocks, each layer (or bed) is younger than the one beneath it and older than the one above it. Therefore, if a sequence is undeformed, the oldest layers will be at the bottom and the youngest at the top. This principle is fundamental in geology for understanding the relative ages of rock layers and the history of the Earth.
What are the layers found in sedementary rocks called?
They're called strata. Strata less than 1cm thick are Laminae.
What law suggests that older rock strata are at the bottom and younger rock strata are at the top?
The law that suggests that older rock strata are at the bottom and younger rock strata are at the top is the law of superposition. This principle states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest at the top due to the natural layering process over time.
When is water its densest?
Water is densest at 4 degrees Celsius. At this temperature, the hydrogen bonds in water are arranged in a way that maximizes the density of water molecules.
What are the layers of sedimentary rocks called?
Strata (singular: stratum)
