The continental crust is the thick, solid outer layer of the Earth that forms the continents. It is primarily composed of lighter, granitic rocks and is less dense than the underlying oceanic crust. Typically, the continental crust varies in thickness from about 30 to 70 kilometers (19 to 43 miles) and plays a crucial role in supporting terrestrial ecosystems and human activities. Its formation is a result of geological processes such as plate tectonics, volcanic activity, and erosion over millions of years.

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.
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
Which portion of the continental margin serves as a boundary between the oceanic crust and continental crust?
continental slope
When continental crust and oceanic crust collide which one will subduct?
Oceanic crust is denser than continental crust, so when they collide, the oceanic crust will subduct beneath the continental crust. This subduction process can lead to the formation of volcanic arcs and mountain ranges.
What are the two types of crust and which rocks make up each crust?
there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x
Which is thicker continental crust oceanic crust?
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
Why is the ocean crust thinner than the continental crust?
It is not. The oceanic crust is thinner than the continental crust!
Is the continental crust thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
Oceanic crust is than continental crust.?

What is the boundary between the oceanic crust and the continental crust known as?
The boundary between the oceanic crust and continental crust is known as the continental shelf. This is the shallowest part of the ocean that extends from the shore to the continental slope.
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.
Is the continental crust liquid?
The continental crust is land, it is perfectly solid.
Which type of crust typically comprises the continental margin?
The continental margin typically consists of a combination of continental crust that extends from the shoreline to the continental shelf's outer edge, where it transitions into oceanic crust of the ocean basin.
What type of crust is thicker Continental or Oceanic?
Continental crust is generally thicker than oceanic crust. Continental crust can be up to 70 km thick, while oceanic crust is usually around 5-10 km thick.
The two types of crust?
Oceanic and Continental crust. Oceanic crust is made of basalt. Continental crust is made of granite
