Iron rich volcanic rock that makes up much of the ocean floor is?
Basalt is the iron-rich volcanic rock that makes up much of the ocean floor. It forms from the cooling and solidification of magma that erupts through underwater volcanic activity, such as mid-ocean ridges. Basalt is a key component of Earth's oceanic crust.
What type igneous rock makes up most of the ocean floor?
Basalt
What type of rock makes up the ocean floor?
The ocean floor is primarily made up of basalt rock, which is a type of igneous rock formed from solidified lava. Basalt is dark in color and forms through volcanic activity at mid-ocean ridges and hotspots.
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
What type of rock is organic rock?
An Organic rock is an Sedimentary rock and it is made in the ocean from calcium and other minerals building up on the ocean floor :)
How is new rock added to the ocean floor?
New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.
On the ocean floor where is the oldest rock?
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
Do minerals come from the ocean?
yes, the minerals come from rock chimneys on the ocean floor
Is the underlying rock beneath the ocean floor silica?
The underlying rock beneath the ocean floor is primarily basalt, which is a mafic rock rich in iron and magnesium. Silica-rich rocks like granite are typically found in continental crust, not beneath the ocean floor.
What material makes the seafloor?
Away from the continental slopes, the ocean floor crust is basalt. That is generally covered by silt, though there are areas of bare rock
What is the habitat of a octopuse?
The octopus habitat depends on the type of octopus. The majroity of octopus makes it home on the ocean floor in cracks and crevices in the rock formations.
You find a rock deep in the ocean that contains a fossil What kind of rock is this?
Sedimentary is found below the ocean floor or area with water
