What type of plate movement causes mid ocean ridges and sea floor spreading?
Mid-ocean ridges and seafloor spreading are characteristics of oceanic diverging plates, plates that are moving away from each other.
What layer causes seafloor spreading?
sea-floor spreading is caused by deep-ocean trenches that overflows and makes a new layer come out. heres a video if you would like to watch it.science.discovery.com/videos/...shorts-sea-floor-spreading.html
What boudaries produces volcanoes?
Convergent boundaries produce volcanoes. Volcanoes form when an oceanic plate and a continental plate converge, causing the oceanic plate to subduct. The subduction causes a magma chamber to form which feeds the volcano when it erupts.
What causes volcanoes to form at spreading plate boundaries?
As two plates spread apart from each other at the boundary, magma that was trapped below wells up between them. This magma can be released in the form of volcanoes or ooze out from rift valleys.
What causes volcanoes to form at a spreading plate boundary?

What kind of activity causes seafloor spreading?
Tectonic.
How Does Seafloor Spreading Effect Continental Drift?
the primary force that causes the seaffloor to spread and contienents to drift
What type of plate movement causes mid ocean ridges and sea floor spreading?
Mid-ocean ridges and seafloor spreading are characteristics of oceanic diverging plates, plates that are moving away from each other.
Which process causes the earth's crust to be continuously formes by volcanic activity?
Seafloor spreading
What causes volcanoes to form at spreading boundaries?
Please make the question clearer. There are converging and diverging boundaries but not spreading boundaries. Plates move but don't spread. Please make the question clearer

Which evidence causes most scientists to believe that seafloor spreading occurs at the mid-atlantic ridge?
Oceanic crust on both sides ofthe ridge shows matching patterns of reversed and normal magnetic polarity
What causes volcanoes to form at a spreading plate boundary?
As two plates spread apart from each other at the boundary, magma that was trapped below wells up between them. This magma can be released in the form of volcanoes or ooze out from rift valleys.
What causes the seafloor to spread?
rising molten magma
What causes volcanoes to form a spreading boundary?
The lava that erupts from a volcano may flow down the sides of the volcano's cone and spread out at the foot, so widening the extent of the lava's boundary.
