Which rock layer is the oldest and why?
The oldest rock layer is typically found at the bottom of a sequence of sedimentary layers, following the principle of superposition in geology. This principle states that in an undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest at the top. Therefore, the rock layer closest to the Earth's surface is usually the youngest, while the rock layer at the bottom is the oldest.
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.
Is there one kind of rock that cannot change into another kind of rock?
No every rock is able to change into anther
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 rock layers?
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.
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 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.

Which weathering process results from the removal of minerals in soil of rock?
Erosion is the weathering process that results from the removal of minerals in soil or rock. It involves the transportation of material from one location to another through the action of water, wind, or ice.
Which rock layer is the oldest and why?
The oldest rock layer is typically found at the bottom of a sequence of sedimentary layers, following the principle of superposition in geology. This principle states that in an undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest at the top. Therefore, the rock layer closest to the Earth's surface is usually the youngest, while the rock layer at the bottom is the oldest.
What is name of material washed down from one rock layer to another?
The material washed down from one rock layer to another is called sediment. Sediment can consist of various particles such as sand, silt, and clay that are transported by water, wind, or ice and deposited in a new location. Over time, these sediments can become compacted and cemented together to form sedimentary rocks.
Which rock layer was deposited last?
The topmost rock layer is the one that was deposited last, as rock layers are typically deposited in a vertical sequence with the oldest layers at the bottom and the youngest layers at the top.
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.
What is one kind of rock that results from the metamorphism of limestone?
Marble is one.
