The Different Layers Of The Earth Quiz Questions
This practice quiz will help you review the different layers of the earth.
- 1.
What is the inner most layer of the earth?
- A.
Inner core
- B.
Outer core
- C.
Mantle
- D.
Crust
- E.
Asthenosphere
Correct Answer
A. Inner coreExplanation
The inner core is the innermost layer of the Earth. It is a solid, dense sphere made mostly of iron and nickel. The high pressure at the center of the Earth keeps the inner core solid, despite its extremely high temperature. It is believed to be about 1,220 kilometers in radius. The inner core plays a crucial role in generating Earth's magnetic field.Rate this question:

What is the outer most layer of the earth?
- A.
Inner core
- B.
Outer core
- C.
Mantle
- D.
Crust
Correct Answer
D. CrustExplanation
The crust is the outermost layer of the Earth. It is the thinnest layer, ranging from 5 to 70 kilometers in thickness. It is composed of solid rock and is divided into two types: continental crust and oceanic crust. The continental crust is thicker and less dense than the oceanic crust. The crust is where we live and where most geological activity, such as earthquakes and volcanic eruptions, occurs. It is also the layer where the Earth's surface features, such as mountains and valleys, are formed.Rate this question:

Which layer of the earth consists of molten?
- A.
Inner core
- B.
Outer core
- C.
Mantle
- D.
Crusts
- E.
Lithosphere
Correct Answer
B. Outer coreExplanation
The outer core is the layer of the Earth that consists of molten material. It is located between the inner core and the mantle. The high temperatures and pressure in the outer core cause the iron and nickel alloys to be in a liquid state. This molten material is responsible for generating Earth's magnetic field through the process of convection.Rate this question:

- 4.
Which layer of the earth is a solid and why?
- A.
The inner core is solid because of the movement of the outer core.
- B.
The inner core is solid because of the low pressure and below freezing temperatures.
- C.
The inner core is solid because of a balance between hot and cold temperatures.
- D.
The inner core is solid because of the high pressure that drop the temperature inside the core.
- E.
The inner core is solid because of the sky high pressure and temperatures.
Correct Answer
E. The inner core is solid because of the sky high pressure and temperatures.Explanation
The inner core is solid because of the sky high pressure and temperatures. The immense pressure at the center of the Earth, caused by the weight of the layers above, compresses the materials in the inner core so tightly that they become solid. Additionally, the temperatures in the inner core are extremely high, reaching up to 5700 degrees Celsius. These extreme pressure and temperature conditions are what keep the inner core in a solid state.Rate this question:

Which layers make up the asthenosphere?
- A.
Crust, mantle, and core
- B.
Bottom part of the upper mantle
- C.
Crust, and uppermost part of the mantle
- D.
Only the crust
- E.
The asthenosphere does not exist
Correct Answer
B. Bottom part of the upper mantleExplanation
The asthenosphere is a layer in the Earth's mantle, located below the lithosphere. It is characterized by its semi-fluid nature, where rocks are able to flow and deform over long periods of time. The correct answer, "Bottom part of the upper mantle," accurately describes the location of the asthenosphere within the Earth's layers.Rate this question:

Which layers make up the lithosphere?
- A.
Crust, mantle, and core
- B.
Bottom part of the upper mantle
- C.
Crust and uppermost part of the mantle
- D.
Only the crust
- E.
The lithosphere does not exist.
Correct Answer
C. Crust and uppermost part of the mantleExplanation
The lithosphere is composed of the crust and the uppermost part of the mantle. The crust is the outermost layer of the Earth, while the uppermost part of the mantle lies just beneath it. Together, these layers make up the lithosphere, which is the rigid outer layer of the Earth's surface.Rate this question:

Which layers make up the tabosphere?
- A.
Inner and outer core.
- B.
Mantle.
- C.
Inner core, outer core, and mantle
- D.
Crusts and mantle.
- E.
The tabosphere doe not exist.
Correct Answer
E. The tabospHere doe not exist. -
- 8.
The mantle makes up ___________ of the Earth's volume.
Correct Answer
80%, eighty percent, 80 percentExplanation
The mantle is a layer of the Earth that lies between the crust and the core. It is the largest layer by volume and makes up approximately 80% of the Earth's total volume. This means that the mantle occupies a significant portion of the Earth's interior, playing a crucial role in the planet's structure and dynamics.Rate this question:
- 9.
The crust and the uppermost part of the mantle make up the __________.
Correct Answer
lithosphere, LithosphereExplanation
The crust and the uppermost part of the mantle make up the lithosphere. The lithosphere is the rigid outer layer of the Earth, consisting of the crust and a portion of the upper mantle. It is divided into several tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere is responsible for the formation of continents, ocean basins, and the movement of tectonic plates.Rate this question:
- 10.
The bottom part of the upper mantle makes up the __________.
Correct Answer
asthenosphere, AsthenosphereExplanation
The bottom part of the upper mantle is known as the asthenosphere. The asthenosphere is a layer of the Earth's mantle that is located just below the lithosphere. It is characterized by its semi-fluid nature and its ability to flow slowly over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates and is responsible for processes such as plate tectonics, volcanic activity, and the formation of mountain ranges.Rate this question:
- 11.
Which layer lies directly above the inner core?
- A.
Mantle
- B.
Crust
- C.
Outer core
- D.
Lithosphere
Correct Answer
C. Outer coreExplanation
The outer core is the layer that lies directly above the inner core. The inner core is the solid, innermost layer of the Earth, and the outer core surrounds it. The outer core is composed of liquid iron and nickel, and it is responsible for generating Earth's magnetic field. The mantle is the layer above the outer core, and it is made up of solid rock. The crust is the outermost layer of the Earth, and it is the thinnest layer. The lithosphere refers to the rigid outer part of the Earth, which includes the crust and a portion of the upper mantle.Rate this question:

Which layer lies directly above the outer core?
- A.
Asthenosphere
- B.
Crust
- C.
Mantle
- D.
Inner core
- E.
All of the above
Correct Answer
C. MantleExplanation
The mantle lies directly above the outer core. The Earth's mantle is a layer of hot, semi-solid rock that extends from the crust to the outer core. It is located between the crust and the outer core and is the thickest layer of the Earth. The mantle is responsible for convection currents that drive plate tectonics and is composed of solid rock that can flow slowly over long periods of time.Rate this question:
