crust
Q. What are the three layers of the earth answer?
The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core.

Q. What are the three layers of Earth Class 7?
Three main layers are classified into the Earth-Crust (outermost), mantle and core (innermost).
Q. Which type of crust is thicker?
continental crust
Q. Why are there two types of crust?
Because continental crust is less dense than oceanic crust it floats higher on the mantle . The mantle, oceanic crust and continental crust have different densities because they are made of different kinds of rock with different densities. The oceanic crust scarcely floats on the mantle.
Q. Which type of crust is the thickest the thinnest?
The crust is thickest under high mountains and thinnest beneath the ocean. The continental crust consists of rocks such as granite, sandstone, and marble. The oceanic crust consists of basalt.
Q. What is the difference between crust mantle and core?
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal.
Q. What separates crust from mantle?
Moho
Q. Which is thicker the lithosphere or the crust?
The lithosphere is the outer solid part of the earth, including the crust and uppermost mantle. The lithosphere is about 100 km thick, although its thickness is age dependent (older lithosphere is thicker).
Q. What is the percentage of crust mantle and core?
Although the core and mantle are about equal in thickness, the core actually forms only 15 percent of the Earth’s volume, whereas the mantle occupies 84 percent. The crust makes up the remaining 1 percent.
Q. What are the main features of the mantle and the core?
THE MANTLE IS ONE OF THE THREE MAIN LAYERS OF THE EARTH.IT LIES BETWEEN THE INNERMOST LAYER, THE CORE AND THE THIN OUTERMOST LAYER , CRUST. THE MANTLE CONSISTS OF HOT,DENSE SEMISOLID ROCK AND IS ABOUT 2,900 KILOMETERS(1,800 MILES) THICK. MOVEMENT IN MANTLE CAUSES VOLCANIC ERUPTIONS AND EARTHQUAKES.
Q. How do you compare the densities of Earth’s crust mantle and core?
The atmosphere and Earth’s interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth’s core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
Q. How dense is the inner core?
12.2 g/cm3
