Quiz Over Layers Of The Earth
The earth is made up of different layers that have different compositions and properties; they are responsible for how the continents are formed. All the layers play a certain role on earth and give answers to some occurrences on earth. Take the quiz below and see just how well you understand the layers.
- 1.
Where is the lithosphere located on Earth?
- A.
Right above the mantle
- B.
Inside the outer core
- C.
On the crust
Correct Answer
C. On the crustExplanation
The lithosphere is located on the crust of the Earth. The lithosphere is the outermost layer of the Earth and is made up of the crust and the uppermost part of the mantle. It is a rigid and solid layer that includes the continents, oceanic crust, and the underlying uppermost part of the mantle. This layer is divided into tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere plays a crucial role in plate tectonics and is where most geological activity occurs, including earthquakes, volcanic eruptions, and the formation of mountains.Rate this question:

This is the most dense layer of the earth:
- A.
Mantle
- B.
Outer core
- C.
Crust
- D.
Inner core
Correct Answer
D. Inner coreExplanation
The inner core is the most dense layer of the Earth. It is a solid, iron-rich sphere located at the center of the Earth. The immense pressure at the core causes the iron to be in a solid state, despite its high temperature. The inner core is believed to have a density of about 13 grams per cubic centimeter, making it the densest layer of the Earth. Its high density is due to the compression of the iron atoms under extreme pressure.Rate this question:

As you travel deeper into the Earth, the pressure:
- A.
Does nothing; there is no pressure
- B.
Stays the same
- C.
Decrease
- D.
Increases
Correct Answer
D. IncreasesExplanation
As you travel deeper into the Earth, the pressure increases. This is because the weight of the overlying rocks and materials creates a force that pushes down on the layers beneath. The deeper you go, the more layers of rock and material there are above, resulting in a greater force and therefore increased pressure.Rate this question:

- A.
True
- B.
False
