What else can I help you with?
Where new crust is being formed?
New oceanic crust is continually being created at the Mid-Ocean ridges.
Is crust being destroyed or created?
near ocean trenches.
Places where new seafloor is being created?
New seafloor is created at mid-ocean ridges, where tectonic plates are moving apart. As the plates separate, magma from the mantle rises to the surface, solidifies, and forms new crust. This process is known as seafloor spreading.
Where is the only significant land surface on which new crust is being created by rifting?
The only significant land surface where new crust is being created by rifting is the African Rift Valley, specifically the East African Rift. This region is where the African Plate is pulling apart, causing the formation of new crust as magma rises to fill the gap created by the separation of tectonic plates.
Does seafloor spreading cause the earth's crust to expand?
Yes, seafloor spreading is a process where new oceanic crust is formed at mid-ocean ridges, causing the Earth's crust to expand. This occurs as magma rises to the surface, solidifies, and pushes older crust away from the ridge, creating new seafloor.

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.
Where is oceanic crust created?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
Is new crust created at a convergent boundary?
No, new crust is not created at a convergent boundary. Instead, at convergent boundaries, two tectonic plates come together and one plate is usually forced beneath the other in a process called subduction. This process can lead to the destruction of crust rather than the creation of new crust.
How can crust disappear at the edge of the boundary?
New crust is being added to the other edge of the boundary
Why is rock formed at th ridges called new rock?
Since the rock just came up and cooled, it's "new oceanic rock." Because... it's new rock. It's the youngest rock. It just came out of the ground and cooled, making it rock. Or Because new crust is being formed while the old crust is being pushed away.
Why does new crust form but the earth doesn't get larger?
New crust is constantly being formed at mid-ocean ridges through volcanic activity. However, the Earth does not get larger because as new crust is formed, older crust is subducted back into the mantle at subduction zones, maintaining a relatively constant amount of crust on the Earth's surface.
Where is new crust being generated?
New crust is being generated at divergent plate boundaries, where tectonic plates are moving away from each other. This process occurs at mid-ocean ridges, like the Mid-Atlantic Ridge, where magma rises up to create new oceanic crust as it solidifies.
