Is the sea floor spreading constructive or destructive?
Sea floor spreading is considered a constructive process because it involves the formation of new oceanic crust at mid-ocean ridges. As tectonic plates move apart, magma rises to the surface and solidifies, creating new crust. This process helps in the continuous renewal of the oceanic lithosphere.
Is spreading sea plates pulling apart?
Yes, spreading sea plates are moving away from each other due to the process of seafloor spreading, which occurs at mid-ocean ridges. This movement allows magma to rise from the mantle, creating new crust and pushing the existing plates apart.
What is a constructive force caused by the convection currents in the earths mantle?
A constructive force caused by the convection currents in the Earth's mantle is seafloor spreading. As the hot mantle material rises and spreads apart at mid-ocean ridges, new crust is formed from solidifying magma. This process contributes to the continuous expansion of the ocean basins and the movement of the tectonic plates.
What is it called when two oceanic plates move apart and new crust is formed?
This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
What is it called when the earth's plates spread apart?
When Earth's plates spread apart, it is known as seafloor spreading. This process occurs at mid-ocean ridges where new crust is formed as magma rises up from the mantle and solidifies. As the plates move apart, they create new oceanic crust.
Is the sea floor spreading constructive or destructive?
Sea floor spreading is considered a constructive process because it involves the formation of new oceanic crust at mid-ocean ridges. As tectonic plates move apart, magma rises to the surface and solidifies, creating new crust. This process helps in the continuous renewal of the oceanic lithosphere.
What are spreading boundaries?
Spreading boundaries are places where two plates move apart.
What is is a spreading boundary?
a spreading boundary is when 2 plates spread apart from each other.
What a spreading center and what is made at one?
Sea floor spreading 2 oceanic plates coming apart
At what boundary does sea-floor spreading occur?
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
Is spreading sea plates pulling apart?
Yes, spreading sea plates are moving away from each other due to the process of seafloor spreading, which occurs at mid-ocean ridges. This movement allows magma to rise from the mantle, creating new crust and pushing the existing plates apart.
What is the name of the boundary were to plates of the earths crust move apart?
Constructive because new land is 'constructed'
How does the movement of tectonic plates and continents relate?
When the plates drift apart through sea floor spreading, so do the continents
Why are divergent boundaries considered constructive while convergent boundaries are considered destructive?
At a constructive (divergent) plate boundary, new crust is being created to infill the gaps caused by spreading plates. At a destructive (subduction-convergent) plate boundary, old, dense oceanic crust is diving into, and becoming part of the mantle.
Does two plates moving apart cause sea floor spreading?
Yes, two tectonic plates moving apart can cause sea floor spreading. As the plates separate, magma rises up to fill the gap, solidifying to form new oceanic crust. This process contributes to the expansion of the ocean basins.
What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
What is it called when plates are spreading?
When tectonic plates are spreading apart, the phenomenon is known as "divergent tectonics" or "divergent boundaries." This occurs at mid-ocean ridges, where new oceanic crust is formed as magma rises to the surface. As the plates move apart, it can lead to geological features such as rift valleys and increased volcanic activity.
