The Clastic sedimentary rock is a rock made out of rock particles so if these rock particles float to the bottom of water such as an ocean or lake and will settle there. Hope this answered your question!! xD
The rock on the ocean floor is from a mid-ocean ridge that runs through the Earth. It takes hot molten material and pushes it up through the ridge. It cools quickly when it hits the cold water and from there, spreads out. This process is called sea-floor spreading! :)
Classically, it is Basalt, however it could be any 'Basic' or 'Mafic' rock similar to Basalt. Basalt is most common because it is formed due to rapid cooling, which is classically the case on the ocean floor with tonnes of water carrying the heat away. This forms small crystals, which define Basalt.
Depends. As it can vary.
In areas of where there is volcanic activity, new sea floor is "built" or extruded from igneous materials (eg. volcanic islands and the mid-Atlanic ridge).
In other parts of the world the sea floor is sedementary in nature, through being built up from eroded river deposits.
And of course there are areas where the two types meet and the origin is metamorphic.
it should also be noted that erosion takes place in the ocean as well, so that the erosion of one type of rock can expose a different type of rock below it.
Most of the oceanic plates are comprised of the igneous rock basalt with a depositional sedimentary rock veneer.
The oceanic crust is predominantly basaltic rock with a varying thickness of overlying sediments.
Solidification of magma on the ocean floor..
The volcanic rock that makes up most of the ocean floor is called sediment.
Pangaea probably?
Probably consolidated sediments (sedimentary rock), then the rock basalt.
theory that explains how continents reached their current place
In the igneous rock composing the oceanic crust.
Forms by lava from volcanoes on the sea floor
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.

Chalk is a form of limestone, a sedimentary rock.
Primarily lime stone.
because we are idiots
Oceanic crust is primarily composed of the rock basalt.
