Is a new oceanic crust formed at a transform fault boundary?

No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.


Earth's radius and surface area are slowly increasing to accommodate the new oceanic crust being formed at mid-oceanic ridges - true or false?

False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.


When two geologic plates are moving away from each other what happens?

When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.


Is new oceanic crust formed at mid-ocean ridges?

Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.


Where did the crust on the Earth come from?

The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.


Where did the crust from the earth come from?

The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.


The youngest parts of Earth's crust is what?

The youngest crust is nearest the mid-oceanic ridges, where new crust is formed from upwelling magma.


Where are oceanic crust and lithosphere formed?

Oceanic crust and lithosphere are formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies to create new oceanic crust at these divergent plate boundaries. As the new crust forms, it pushes the older crust away from the ridge axis, creating a continuous process of crust formation and movement.


How does the age of oceanic crust compare to the age of continental crust?

Oceanic crust is generally younger than continental crust. Oceanic crust is continuously formed at mid-ocean ridges through volcanic activity and then gradually moves away from the ridge, undergoing processes that make it relatively young compared to the older continental crust.


What formed when lava cools and crystallizes on top of oceanic crust?

it becomes part of the oceanic crust


Where would the youngest crust on the Earth be found?

The youngest crust on Earth is typically found at mid-ocean ridges, where tectonic plates are moving apart and new crust is formed through volcanic activity. This process is known as seafloor spreading, and it results in the continuous creation of young oceanic crust.


Is a new ocean crust formed at a divergent boundary?

because the molten rock cools in the water and forms a oceanic crust
