The layers are known as "beds".
Limestone is one of the Sedimentary class of rocks, which start as sediments on, usually, the floor of a sea or lake.
Most limestones, including chalk, are from sea-bed accumulations of silt rich in Calcium Carbonate. Over time their own dead weight compresses them, driving out the water and initiating a process of "Lithification" - chemical and physical changes that turn the soft sediment into hard rock.
That's the rock made. Now to emplace it...
Summarising, over geological time, Earth-movements uplift the former sea-beds into hills and mountains, where the weather promptly starts to weather and erode them back into sediment for transport by rivers or glaciers back to the sea to start the cycle anew...
The beds simply reflect the original sediment deposits: changes in sediment supplies or characteristics, often reflecting climate changes, break the steady deposition to form interruptions known as "bedding planes".
The beds are all generally horizontal to start with, but the uplift processes is often accompanied by folding and faulting that can tilt the beds up at angles, in some cases even past 90 degrees so they slope "upside down".

What would you find under Kaibab limestone if you were to drill a hole into the Kaibab limestone?
Layer after layer of sedimentary rock, then eventually metamorphic and igneous rock. The layer directly underneath the Kaibab is the Toroweap Formation, a layer of darker limestone.
What is the second layer of the grand canyon made of?
Probably Kaibab limestone, Coconino sandstone, Hermit shale, Redwall limestone, Muav limestone, Vishnu Schist, and other layers.
Which rock layer is at level in Nankoweap Canyon?
layer 4 ,muau , limestone
Where is limestone formed in the earths crust?
Limestone started as the shells of marine animals. It started at the floor of the ocean and, layer-upon-layer, the shells became compressed and cemented together to form the sedimentary rock.
How old is the supai layer?
The Supai layer is approximately 285 million years old. The Supai layer forms the surface of the Coconino and the Kaibab plateaus. It is composed major of limestone and sandstone.
Why is water acidic when it reaches a limestone layer?
it the limestone is acidic

When a granite intrudes into a layer of limestone which is younger granite or limestone?
granite
What layer of soil is limestone in?
sedimantary

What causes limestone to harden with age?
the limestone harden because theirs another layers of limestone on top of it which pushes the bottom layer and flatten it.
What happened between the formation of Columbia limestone and the marden creek shale?
the creek dried up and made shale, then what could of happened is it made a layer of shale and later limestone formed and made a layer of limestone on top of shale

What is sedimentary rock formed for deposits of shells?
Limestone is created in small warm still waters where shells and other sediments create layer which in time turn into Limestone.
Which is required for karst topography to form?
Groundwater dissolves limestone, which causes sinkholes to form
