What is it when plates move farther and farther apart?
When plates move farther and farther apart, this is known as seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is formed as plates diverge. This process is driven by convection currents in the Earth's mantle.
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.
What pushes the tectonic plates apart?
The process that pushes tectonic plates apart is called seafloor spreading. Magma rises from the mantle through divergent boundaries, creating new oceanic crust. As the new crust forms, it pushes the existing plates away from each other, causing them to move.
Do continental plates move faster than oceanic plates?
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
What cause seafloor spreading?
valconoes!
Im the gap that forms as tectonic plates move apart?
You are a mid-ocean ridge that forms when tectonic plates move apart and new oceanic crust is created through volcanic activity. This process is known as seafloor spreading, and it results in the formation of new oceanic crust at the mid-ocean ridge.
Long crack that forms as two tectonic plates move apart?
A long, linear crack that forms as two tectonic plates move apart is called a mid-ocean ridge. This type of boundary is where new oceanic crust is created as molten rock rises up from the mantle and solidifies along the spreading center. Over time, as the plates continue to move apart, the new crust forms a continuous ridge on the ocean floor.
How are divergent plates different from convergent plates?
Divergent Boundaries happen when two plates (oceanic or contental) begin to diverge, or move apart. Convergent Boundaries occur when two plates (again, oceanic or contential) begin to converge or move apart
What is the structure that forms as tectonic plates move apart?
On continents it is called a Rift Valley or Graben. in the ocean it is call a Mid Oceanic Ridge.
What forms when two lithospheric plates move apart?
When two lithospheric plates move apart, a divergent boundary is formed. This process results in the creation of new oceanic crust as magma rises to fill the gap between the plates, forming a mid-ocean ridge.
What happen as some plates move apart?
New oceanic plates/crust are created in the space of separation.
What feature forms at diverging oceanic plates?
Mid-ocean ridges form at diverging oceanic plates. As the plates move apart, magma rises to fill the space, creating new oceanic crust. This process results in the formation of underwater mountain ranges along the divergent boundary.
Two tectonic plates under water move apart and magma fills the space between them This is an example of?
This is an example of seafloor spreading, a process where tectonic plates diverge and new oceanic crust forms as magma rises and solidifies at mid-ocean ridges. As the plates move apart, they create new oceanic lithosphere and contribute to the Earth's tectonic activity.
Is true or false oceanic lithosphere is created at divergent boundaries?
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
At a mid Ocean ridge how do the two tectonic plates move?
At a mid-ocean ridge, tectonic plates move apart from each other due to seafloor spreading. Magma rises up from the mantle, solidifies at the ridge, and forms new oceanic crust. This process pushes the plates away from each other, causing them to move in opposite directions.
What forms when two crustal plates move apart?
an earthquake
When two plates move apart underwater what forms?
