Seafloor spreading at mid ocean ridges produces magma and later igneous rocks that are mostly basaltic. Being a mafic rock, it ejected from a mid ocean ridge so it is extrusive. Often it is aphanitic and visicular. Basalt is most common on sea floors because the magma that is melted is comprised of mostly mafic rocks.

Divergent Plate Boundary. (Seafloor Spreading).


What kind of activity causes seafloor spreading?

Seafloor spreading is caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates separate, magma rises to the surface, solidifies, and creates new oceanic crust. This process is part of the theory of plate tectonics.


What kind of fault occurs at the divergent plate boundaries?

A normal


This kind of action causes thinning plates?

Plate tectonics can lead to the thinning of plates when they separate at divergent boundaries. As plates move apart, magma rises to fill the gap, creating new crust and causing the existing plates to stretch and thin out. This process is known as seafloor spreading.


What kind of boundary can sea floor spreading occur?

subducting


What kind of crust is nearly always created at a rift zone?

Mid-ocean ridges are a line of volcanic mountains under the oceans between the continents. As the oceanic plates are being pulled apart by the processes of plate tectonics, magma is formed from decompression melting in the mantle, and rises upward to fill in the gap that is created. Because this material solidifies and is still hot, it is buoyant and rises higher than the surrounding seafloor, creating the ridges. As it is pulled away from the spreading point by plate tectonics, it gradually cools, making it less buoyant; it gradually drops in elevation.

The ocean floor spreading from the ridge what are three kind of evidence scientist have found to support this ideas?

Three types of evidence supporting the idea of seafloor spreading include magnetic striping of the ocean floor (paleomagnetism), the presence of young volcanic activity near mid-ocean ridges, and the discovery of deep-sea hydrothermal vents that release hot mineral-rich water. These pieces of evidence suggest that new oceanic crust is continuously forming at mid-ocean ridges and spreading outward.

What kind of rock is formed when the shells of clams and oysters collect on the seafloor?

When shells of clams and oysters accumulate on the seafloor, they can form a type of sedimentary rock known as limestone. Specifically, if the shells are primarily composed of calcium carbonate, they may become calcitic limestone as they undergo lithification through compaction and cementation over time. This process transforms the accumulated organic material into solid rock, often containing fossilized remains of the original organisms.
