New rock is formed near the mid-oceanic ridge as oceanic plates diverge or separate from each other. Hot rocks rising from the asthenosphere melt from decompression as they rise, filling the fault and forming new basaltic oceanic crust. As new crust is added, older crust is pushed away. Therefore, the further away from the mid-oceanic ridge, the older the crustal rocks.
The youngest oceanic crust is found near divergent plate boundaries because this is where tectonic plates are moving away from each other. As the plates separate, magma rises to fill the gap created by the moving plates, solidifying to form new crust. This process is continuous and results in the formation of young oceanic crust at divergent boundaries.
Because magma is rising up through cracks in the surface of the Mid-Atlantic ridge, creating new rock at the bottom of the ocean.

Is true or false oceanic lithosphere is created at divergent boundaries?
True. Oceanic lithosphere is created at divergent boundaries where tectonic plates move away from each other. Magma rises from the mantle to fill the gap and solidifies to form new oceanic crust.
At which type of plate boundary is the youngest seafloor located?
The youngest seafloor is located at mid-ocean ridges, which are divergent plate boundaries where tectonic plates move apart. As new oceanic crust is formed through seafloor spreading, it pushes older crust away from the ridge, making the seafloor at mid-ocean ridges the youngest on Earth.
What plate boundaries are where the crust forms?
Mid-ocean ridges are divergent plate boundaries where new oceanic crust forms as tectonic plates move apart. At these boundaries, magma rises from the mantle, cooling and solidifying to create new crust.
Are divergent boundaries where new crust is formed?
Yes, divergent boundaries are where tectonic plates move away from each other. As they separate, magma from below the Earth's surface rises to fill the gap, solidifying into new crust. This process is known as seafloor spreading when it occurs underwater, creating new oceanic crust.
Are convergent boundaries and sea-floor spreading related in any way?
Yes, convergent boundaries and sea-floor spreading are related in the sense that sea-floor spreading can occur at divergent boundaries (where tectonic plates move apart), leading to the creation of new oceanic crust. This new oceanic crust can then be consumed at convergent boundaries (where tectonic plates collide), as one plate is subducted beneath the other.
New crust forms what kind of new boundaries?
New crust forms at divergent boundaries, where tectonic plates move away from each other. This process can occur in oceanic or continental crust.
A geologic feature of divergent plate boundaries in oceanic crust is the formation of?
rift valleys
Is true or false oceanic lithosphere is created at divergent boundaries?
True. Oceanic lithosphere is created at divergent boundaries where tectonic plates move away from each other. Magma rises from the mantle to fill the gap and solidifies to form new oceanic crust.
Do divergent boundaries everoccur between continental and oceanic crust?
Yes, divergent boundaries can occur between continental and oceanic crust. An example of this is the Mid-Atlantic Ridge, where new oceanic crust is formed as the North American and Eurasian plates move apart. This process leads to seafloor spreading and the creation of new oceanic lithosphere.
What are divergent boundaries?
Divergent boundaries are areas where continental or oceanic plates are moving away from each other and creating new crust. Examples would be the Mid-Oceanic Ridge and the East African Rift Zone.
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
At which type of plate boundary is the youngest seafloor located?
The youngest seafloor is located at mid-ocean ridges, which are divergent plate boundaries where tectonic plates move apart. As new oceanic crust is formed through seafloor spreading, it pushes older crust away from the ridge, making the seafloor at mid-ocean ridges the youngest on Earth.
Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
What plate boundaries are where the crust forms?
Mid-ocean ridges are divergent plate boundaries where new oceanic crust forms as tectonic plates move apart. At these boundaries, magma rises from the mantle, cooling and solidifying to create new crust.
What happens when divergent boundaries occur in the middle of the ocean?
A ridge with transverse faults is formed, where new oceanic crust (seafloor) is formed.
What happens when divergent boundaries occur in the middle of an ocean?
A ridge with transverse faults is formed, where new oceanic crust (seafloor) is formed.
Where is oceanic crust created?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
