What is the characteristic of continental crust?
Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.
What are the two types of crust its characteristics?
Summary
- Oceanic crust is thinner and denser than continental crust.
- Oceanic crust is more mafic, continental crust is more felsic.
- Crust is very thin relative to Earth’s radius.
What are the characteristic of oceanic crust?
Oceanic crust is thinner and more dense than continental crust. This is because it has been compressed by the weight of the oceans it carries above it. It is also much younger than Continental crust, as it is usually less than 200 million years old.
What is the main characteristic of each layer of the Earth?
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.

What are 5 facts about the earths crust?
Facts about Earth’s Crust 5: the continental crust. The continental crust occupies than greater depth than the oceanic crust. It is also thicker. The crust temperature is improved at the deeper areas. It has the average temperature of 392 degrees F to 752 degrees F or 200 degrees C to 400 degrees C. Find facts about Divergent Boundaries here.
What are facts about earths crust?
Earth’s crust is made of several chemical elements, the most abundant of which is oxygen. The gas makes up around 46% of the crust while the different metals and rocks make up the rest.
What are the physical properties of the Earth’s crust?
The earth is split into four major layers: the crust, the mantle, the outer core and the inner core The crust is what humans live on, and it consists of only one percent of the Earth’s mass The centre of the Earth is a solid ball of nickel and iron roughly 70% the size of the moon
What are the 6 layers of the Earth?
Mechanically, it can be divided into lithosphere , asthenosphere, mesospheric mantle, outer core, and the inner core. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core. The geologic component layers of Earth are at the following depths below the surface:
