Oceanic crust is than continental crust.?
younger
What is the difference between the continental crust and the oceanic?
Continental crust is much older, granitic in nature, and less dense than oceanic crust which is composed of basaltic rock. Oceanic crust is in a constant state of creation and destruction through the processes of plate tectonics. Oceanic crust is also considerably less thick than continental crust.
Where does the oceanic crust begin?
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
Do lithospheric plates include both continental crust and oceanic crust?
Yes, lithospheric plates can include both continental and oceanic crust. These plates are composed of the rigid outer layer of Earth's surface, which consists of the upper part of the mantle and the crust. Continental crust is less dense and thicker than oceanic crust, but both can form part of lithospheric plates.
What are most tectonic plates composed of?
Tectonic plates are composed of both oceanic and continental crust. Oceanic plates are predominantly made of basaltic rock, while continental plates are primarily composed of granitic rock. The Earth's lithosphere, which includes the tectonic plates, is made up of these crustal rocks.

Is the continental crust thinner and denser in most areas than the oceanic crust?
No, the continental crust is generally thicker and less dense than the oceanic crust. Continental crust can be up to 70 km thick in some areas, while oceanic crust averages about 7 km in thickness. Density-wise, oceanic crust is denser because it is made mostly of basalt, whereas continental crust is primarily composed of less dense granite and sedimentary rocks.
What is crust of the geosphere?
== == The Crust--The outer skin of the planet is composed of igneous, metamorphic, and sedimentary rock. Continental Crust: Comprised predominately of rocks most resembling granite, the continental crust is relatively thick compared to the oceanic crust with a depth that ranges from 30 km to 50 km. The average specific gravity of continental crustal rock is 2.7. Oceanic Crust: At an average depth of 5 km to 10 km, the oceanic crust is thinner than the continental crust. Oceanic crustal rocks are composed mainly of the igneous rocks basalt, diabase, and gabbro, which are mafic in composition. The average specific gravity of oceanic crustal rock is 2.9.

When Compared to landform crust the ocean crust is?
Compared to continental crust, oceanic crust is generally thinner, denser, and younger. It typically has an average thickness of about 5-10 kilometers, while continental crust can range from 30 to 50 kilometers. Oceanic crust is primarily composed of basalt, whereas continental crust is mostly granite. Additionally, oceanic crust is continuously being formed at mid-ocean ridges, making it geologically younger than most continental crust.
Do lithospheric plates include both continental crust and oceanic crust?
Yes, lithospheric plates can include both continental and oceanic crust. These plates are composed of the rigid outer layer of Earth's surface, which consists of the upper part of the mantle and the crust. Continental crust is less dense and thicker than oceanic crust, but both can form part of lithospheric plates.
What layer of the crust is the most dense?
Oceanic crust is more dense than continental crust.
What are most of tectonic plates made of?
Most tectonic plates are made of both oceanic and continental crust. Oceanic crust is primarily composed of basalt, a dense volcanic rock, while continental crust is made up of granite and other lighter rocks. These differences in composition play a role in the movements and interactions of tectonic plates.
What are most tectonic plates composed of?
Tectonic plates are composed of both oceanic and continental crust. Oceanic plates are predominantly made of basaltic rock, while continental plates are primarily composed of granitic rock. The Earth's lithosphere, which includes the tectonic plates, is made up of these crustal rocks.
What are the three most common elements in Earths continental crust and oceanic crust?
The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.
What is the top most layer of the earth's surface?
The topmost layer of the Earth's surface is called the crust. It is the outermost solid shell of the Earth and is composed of various types of rocks, minerals, and soil. The crust is divided into two types: continental crust, which makes up the continents, and oceanic crust, which forms the ocean floors. The thickness of the crust varies, with continental crust being thicker than oceanic crust.
