As the ocean crust gets older, its density increases. This has helped the continents to stay a float on the earths upper mantle for over a billion years.

Is it true oceanic crust moves away from the mid ocean ridge it cools and becomes more dense?

yes


Is it true that as oceanic crust moves away from the mid-ocean ridge. it cools and becomes more dense?

True.


What force drives the process of pulling dense pieces of oceanic crust downward towards the mantle?

The force driving the process of pulling dense pieces of oceanic crust downward towards the mantle is gravity. As oceanic crust cools and becomes denser, it sinks into the mantle due to gravitational forces. This process is known as subduction.


Why is oceanic crust lower than the continental crust?

Oceanic crust is denser than continental crust because it is formed from basaltic magma at mid-ocean ridges, which cools quickly and is more compact. This denser oceanic crust tends to sink lower into the mantle compared to the less dense continental crust, which is primarily composed of less dense granite rocks.


What is difference of the continental crust and the oceanic crust?

Continental crust is thicker but less dense, and oceanic crust is thinner but more dense, making it heavier.


Why does one continental plate slide under the other?

Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust


What crust is more dense oceanic or continental crust?

Oceanic crust is significantly denser.


What layer of the crust is the most dense?

Oceanic crust is more dense than continental crust.


What is the difference between continential and oceanic crust?

Continental crust is thicker, less dense, and typically older than oceanic crust. Oceanic crust is thinner, more dense, and younger as it is constantly being formed at mid-ocean ridges and being recycled at subduction zones.


What is the difference of continental crust and oceanic crust?

Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt


What portion of the earths crust is more dense oceanic or contenintal?

Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.


What are the two types of crust on the earth?

There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
