Layers of the Earth

• 1.

### Identify the CRUST on the diagram below.

• A.

Layer A

• B.

Layer B

• C.

Layer C

• D.

Layer D

A. Layer A
Explanation
Layer A is the crust because it is the outermost layer of the diagram. The crust is the Earth's outermost layer, and it is composed of solid rock. It is also the thinnest layer compared to the other layers, which are the mantle and the core.

### Identify the MANTLE on the diagram below.

• A.

Layer A

• B.

Layer B

• C.

Layer C

• D.

Layer D

B. Layer B
Explanation
The correct answer is Layer B because the mantle is the layer of the Earth located between the crust and the core. In the diagram, Layer B is positioned between Layer A (crust) and Layer C (core), indicating that it is the mantle.

### Identify the INNER CORE on the diagram below.

• A.

Layer A

• B.

Layer B

• C.

Layer C

• D.

Layer D

D. Layer D
Explanation
The inner core can be identified as Layer D because it is the deepest layer in the diagram. The layers are listed from top to bottom, and Layer D is the last layer mentioned. Therefore, it is the innermost layer and is the correct answer for the inner core.

### On which layer do we live?

• A.

Crust

• B.

Mantle

• C.

Inner Core

• D.

Outer Core

A. Crust
Explanation
The crust is the outermost layer of the Earth, where we live. It is the thinnest layer, making up only about 1% of the Earth's volume. The crust is composed of solid rocks and is divided into two types: continental crust and oceanic crust. The continental crust is thicker and less dense, while the oceanic crust is thinner and denser. The crust is where all the landforms, such as mountains, valleys, and plains, are located, as well as where all life exists, including humans.

### The inner core is made of a solid metal. Why is this?

• A.

No reason, that's just the way it is!

• B.

Because of the intense pressure of the other layers beating down on the core.

• C.

Because the core is so hot the core turns from solid to liquid.

• D.

Because the weight of the crust is beating down on the core.

• E.

None of the above.

B. Because of the intense pressure of the other layers beating down on the core.
Explanation
The inner core is made of a solid metal because of the intense pressure of the other layers beating down on the core. This pressure compresses the metal and prevents it from melting, resulting in a solid state.

### Which layer contains the highest mountains and the deepest oceans?

• A.

Crust

• B.

Mantle

• C.

Inner Core

• D.

Outer Core

A. Crust
Explanation
The crust is the outermost layer of the Earth's surface and contains both the highest mountains and the deepest oceans. This layer is where tectonic plates interact, leading to the formation of mountain ranges such as the Himalayas. At the same time, the crust also includes oceanic trenches, like the Mariana Trench, which is the deepest part of the world's oceans. Therefore, the crust is the layer that encompasses both the highest mountains and the deepest oceans on Earth.

• 7.

### Which layer can be worn down by erosion and weathering (weathering is when weather like rain and wind blow against rocks and break them up)?

• A.

Crust

• B.

Mantle

• C.

Inner Core

• D.

Outer Core

A. Crust
Explanation
The crust is the outermost layer of the Earth's surface and is composed of rocks and soil. It is the layer that is directly exposed to the elements and is therefore susceptible to erosion and weathering. Erosion is the process by which rocks are broken down and carried away by natural forces such as wind, water, and ice. Weathering, on the other hand, refers to the physical or chemical breakdown of rocks caused by exposure to weather conditions like rain and wind. Therefore, the crust is the layer that can be worn down by erosion and weathering.

Rate this question:

• 8.

### Which layer is the coolest (in temperature)?

• A.

Crust

• B.

Mantle

• C.

Inner Core

• D.

Outer Core

A. Crust
Explanation
The crust is the outermost layer of the Earth's surface, and it is the layer that is closest to the atmosphere. Since the crust is exposed to the relatively cooler temperatures of the atmosphere, it is the coolest layer compared to the other layers mentioned. The mantle, inner core, and outer core are all located beneath the crust and are subject to higher temperatures due to their proximity to the Earth's heat-producing core.
