The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
Process that creates new ocean floor from diverging plates.
What is the process called that creates new ocean floor from diverging plates.
Feature s of a divergent plate boundary.
These zones located along mid ocean ridges represent areas where upwelling magma creates new oceanic crust.
Mid ocean ridges rift valleys.
As lava flows from these volcanic ridges it quickly cools forming extrusive igneous rock.
The process by which new material is added to the ocean floor along the boundary between diverging plates.
The rising current pushes up on the bottom of the lithosphere lifting it and flowing laterally beneath it.
New crust is formed at diverging oceanic plates.
Divergent plate boundaries are locations where plates are moving away from one another.
Volcanic mountains are found at this boundary on the continent.
It melts into magma 2.
Others are on land.
A plate is forced below when one plate is denser that another as they converge.
The process when a denser plate sinks below the other plate at a convergent boundary.
Some divergent boundaries are on the ocean floor where the lithosphere is thin.
Feature s of a transform boundary.
Where plates diverge from each other molten magma flows upward between the plates forming mid ocean ridges underwater volcanoes hydrothermal vents and new ocean floor crust.
A tectonic plate that gets subducted is a plate recycled.
It is the structure and geological processes of divergent boundaries that shape the continents and oceans over time by forming new crust and new.
Discussion questions part 2.
This lateral flow causes the plate material above to be dragged along in the direction of flow.
This process that creates new ocean floor from diverging plates is sea floor spreading.
The edges of these continental boundaries usually form zig zag patterns.
Occurs at the continental to oceanic.
Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around.
What forms when 2 oceanic plates move apart.
1 what happens when a tectonic plate gets subducted.
Divergent plates move away from each other creating a rift in the brittle rock of the lithosphere.
Transform boundaries are faults that connect two areas where plates are converging or diverging.
This occurs above rising convection currents.
Continental plates meanwhile are formed primarily by convergent plate boundaries.
The process that creates new sea floor as plates move away from each other at the mid ocean ridges.
A divergent plate boundary.
What features are formed on the continent along this boundary.
Oceanic plates are formed by divergent plate boundaries.
What is the process that creates new ocean floor from diverging plates.
