What is the sequence of rock strips at the oceanic ridges called?
The sequence of rock strips at oceanic ridges is called "oceanic crust." It is formed through the process of seafloor spreading where magma rises through the Earth's crust, solidifies, and creates new crust. This process helps drive the movement of tectonic plates.
What is a oceanic ridges?
a ridge in the ocean
What is mid - oceanic ridges?
mountainous topography
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What causes oceanic ridges?
Oceanic ridges are caused by the divergent movement of tectonic plates. As the plates move apart, magma rises from the Earth's mantle to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.

Why are ophiolites of special interest to geologists?
Ophiolites are of special interest to geologists because they provide a unique window into the processes at mid-ocean ridges and the oceanic lithosphere formation. They contain a complete sequence of oceanic crust and upper mantle rocks that are rarely preserved on the Earth's surface, allowing researchers to study the formation and evolution of oceanic lithosphere in a natural setting. Additionally, ophiolites can provide valuable insights into plate tectonics, mantle dynamics, and crustal accretion processes.
What is oceanic ridges?
a ridge in the ocean
Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
What is mid - oceanic ridges?
mountainous topography
Where is oceanic crust created?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
What is the relationship between distance from the ridges and age of the crust?
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.
Is it true that The Atlantic and Pacific basins have oceanic ridges and the Indian Ocean has no oceanic ridge?
yah
Why does oceanic lithosphere sink at subduction but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
How are oceanic ridges form?
divergent boundaries
Where is the place where seafloor spreading occur?
Mid-oceanic ridges
