Which rock layer is the oldest and why?
the bottom one
What fault causes rocks to become twisted and strained?
A Transform fault where one tectonic plate slides past another tectonic plate results with rocks being pulled apart. Slippage results when the rock of one plate bends the rock of another, causing elastic rebounds and the release of energy as surface waves.
When looking at layers of rock which layer is oldest?
In a normal sequence (ie one that has not been tectonically deformed) the oldest layer is the lowest layer - so the one at the base of the sequence is the oldest. This is called the "law of superposition".
Why do sedimentary rocks often form layers?
because all the different types and weights of the sediments means that some fall through the water faster than others so when they compress into rock the heaviest sediments will be at the bottom etc.
What is the rock cycle including descriptions of how one type of rock can change into another type?
It is called the Rock Cycle.
What layer is the youngest layer in the sedimentary rock?
The one closest to the surface because rock layers are laid down one on top of another.
What is name of material washed down from one rock layer to another?
illuvium
What is the name of the bottom rock layer?
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
What is rock layers?
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.
WHAT KIND OF ROCK FORMS WHEN LAYERS OF PARTICLES SETTLE ON TOP OF ONE ANOTHER AND HARDEN?
The rock that forms when layer of particles settle on top of each other and harden is a sedimentary rock.
What are two results of waves along a coast?
Two results are:A sea arch,when waves erode a layer of softer rock that underlies a layer a hard rock.Another one is a sea cave,which is formed when ocean waves hit against a steep and rocky coast lots of times.

What is one kind of rock that results from the metamorphism of limestone?
Marble is one.
How do geologist use the principle of superposition?
The principle of superposition states that a rock layer on top of another is younger than the one beneath it. Geologists use the principle of superposition to determine the relative ages of rock layers.
Scientists use rock cycle to describe what process?
The rock cycle is how one type of rock can be changed into another type of rock.
