What else can I help you with?
Is earth's continental crust thicker or thinner than the oceanic crust?
On average, it is much thicker than oceanic crust.
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 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 :)
What is the density of oceanic crust?
it is 3.0 g.\cm to the third power. Your welcome.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is denser than continental crust due to its composition and age, causing it to sink lower into the mantle. The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter continental crust.
What is the density of continental crust and oceanic crust?
The specific gravity, on average, of continental crust is 2.7. For oceanic crust, it's 2.9.
How thick is the oceanic crust is?
The oceanic crust has an average depth in the range of 5-10 kilometers.
Which layer of the crust has an average thickness of five miles?
The oceanic crust.
Why is the oceanic crust younger than cretaceous?
This is not true. There is quite some oceanic crust that is older than the Cretaceous still present and we even find small parts of very ancient oceanic crust on the continents as ophiolites. On average the oceanic crust might be of Cretaceous or even younger age because it is constantly recycled into the mantle in subduction zones and created on mid ocean ridges.

Why does the continental crust go father down into the mantle than the oceanic crust?
Continental crust, on average, is much thicker than oceanic crust. Because of the principles of isostacy and buoyancy, the continental crust will protrude more deeply into the asthenosphere than oceanic crust.

What is the average composition of the oceanic crust is thought to approximate?
granite
What is the density of oceanic crust?
it is 3.0 g.\cm to the third power. Your welcome.
How much does the oceanic crust weigh?
The average density of oceanic crust is about 2.9 g/cm^3. Given that oceanic crust is typically around 7 km thick, the weight of a cubic meter of oceanic crust would be approximately 29,000 kg (or 29 metric tons).
What are two way the continental crust and the oceanic crust are different?
the oceanic crust is thinner, generally5-8 killometers thick, and is made of basalt, but the continental crust is an average of 30 km and is made of granite
