Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
Where is old plate material destroyed?
Crust is destroyed (or recycled!) at convergent plate boundaries. Usually between oceanic and continental plates where subduction of the more dense oceanic crust occurs.
What is the age of the continental crust?
The age of the continental crust varies, but on average it is around 2.5 billion years old. This means that most of the continental crust is significantly older than the oceanic crust, which is constantly being recycled through processes like subduction.

Crust is destroyed near?
Crust is destroyed at the convergent plate boundaries in Earth. In between the oceanic and continental plates, the subduction of the denser oceanic crust takes place.
What happens when an oceanic and an oceanic plate collide?
since the oceanic crus is thinner than the Continental crust the oceanic crust get submerged and gets destroyed while the continental crust covers the submerged part as being taken over by continental crust....//\@Rtz Z@r...
How are oceanic crust and continental crust different?
Oceanic crust is denser and thinner than continental crust. Oceanic crust is primarily made up of basalt rock, while continental crust is composed of lighter granite rock. Additionally, oceanic crust is constantly being created and destroyed through seafloor spreading and subduction processes, whereas continental crust is relatively stable.

Which plate boundary destroys crust?
Crust is destroyed at the convergent plate boundary. This is usually between the oceanic and continental plates. This is where subduction of the more dense crust occurs.
Compared to earths continental crust earths oceanic crust is?
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
Differences of the continental crust and oceanic crust?
The continental crust is thicker, less dense, and older than the oceanic crust. It is composed mainly of granite rocks and is found beneath continental landmasses. In contrast, the oceanic crust is thinner, denser, and younger, with basalt rocks being the dominant rock type. It forms the ocean floor and is continually created and destroyed through the process of seafloor spreading and subduction.
Why is the oldest rock on planet earth found on continental plates not oceanic plates?
Oceanic crust is constantly being recycled. New oceanic crust is formed at mid ocean ridges while old ocean crust is destroyed at subduction zones. As a result there is little oceanic crust that is older than 200 million years. Continental crust does not get destroyed by subduction, so much of it has been around since the Precambrian time.
Where is old seafloor destroyed?
Oceanic crust isn't destroyed because it's old; it is, in fact, destroyed due to destructive plate boundaries. This is where a continental plate and an oceanic plate move towards each other. As the oceanic crust is denser, it is pushed under the continental plate. Here it is forced into the mantle of the earth, where it is destroyed due to heat and convection currents.
Where is old plate material destroyed?
Crust is destroyed (or recycled!) at convergent plate boundaries. Usually between oceanic and continental plates where subduction of the more dense oceanic crust occurs.
