Why does ocean crust dive below continental crust?
The ocean crust dives below the continental crust due to a collision. This collision involves the two types of crust and since the oceanic crust is denser, it sinks to the bottom while the less dense continental crust rises to the top.
Ocean crust dives below continental crust because of what?
Because of its higher density, and gravity. One part of plate tectonic theory.
How do the oceanic and continental crust differ?
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
What structure is formed when ocean crust subducts below continental crust?
A deep ocean trench is formed when ocean crust subducts below continental crust. The descending oceanic plate is forced down into the mantle by the more buoyant continental plate. This process can also lead to the formation of volcanic arcs on the overriding plate.
Ocean crust is denser than the continental crust because it contain more of which 3 element?
Ocean crust is typically denser than continental crust because it contains more basalt (rich in iron and magnesium), whereas continental crust is composed of less dense granite (richer in aluminum and silicon).
What happens when the continental crust is over the ocean floor?
because 0ness
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
Why is the ocean crust thinner than the continental crust?
It is not. The oceanic crust is thinner than the continental crust!
Oean crust dives below continental crust because?
Oceanic crust is denser and thinner than continental crust, so when the two converge at a subduction zone, the oceanic crust is forced to sink beneath the less dense continental crust. This process of subduction is driven by the difference in density between the two types of crust, as well as the movement of tectonic plates.
What would happen if ocean crust and continental crust combine?
They weld together into new continental crust.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
