Which type of crust is primarily made of basalt and is more dense?
Oceanic crust is primarily made of basalt and is more dense than continental crust. It is also younger and thinner compared to continental crust.
What are the Differences in height between continental crust and oceanic crust?
Continental crust is generally thicker and more buoyant than oceanic crust, with an average thickness of around 30-50 km compared to about 5-10 km for oceanic crust. This means that continental crust stands higher above sea level compared to oceanic crust, which lies lower below sea level.
Both continental crust and oceanic crust consist mainly of what elements?
Both continental crust and oceanic crust consist mainly of silicon and oxygen, forming silica-based minerals. However, oceanic crust tends to have higher concentrations of iron and magnesium compared to continental crust.
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.
Oceanic crust is denser than the continental crust because it contains more of which three elements?
Oceanic crust is denser than continental crust because it contains more magnesium, iron, and calcium. These heavier elements contribute to the higher density of the oceanic crust compared to the continental crust.
Compared to Earth's continental crust Earth's oceanic crust is?
thinner and denser
What material is oceanic crust rich in?
Iron and magnesium, when compared to continental crust.

What is the composition of continental crust?
The composition of the continental crust is granitic overall, high in silicon and aluminum, when compared to the 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.

Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
Oceanic crust is denser than the continental crust because it contains more of which three elements?
Oceanic crust is denser than continental crust because it contains more magnesium, iron, and calcium. These heavier elements contribute to the higher density of the oceanic crust compared to the continental crust.
What are 2 differences about the cotineantal and oceanic crust?
The two main differences between continental and oceanic crust are their composition and thickness. Continental crust is primarily made up of granitic rocks, which are less dense than the basaltic rocks that make up oceanic crust. Additionally, continental crust is much thicker, averaging around 35 km thick, compared to oceanic crust, which is typically around 7 km thick. These differences in composition and thickness contribute to the contrasting properties and behaviors of continental and oceanic crust in geological processes.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
