Problem Overview:
The task is to identify the layers and sub-layers of the Earth by matching the numbered labels in the diagram with the correct terms provided at the bottom. The diagram shows a cross-section of the Earth, illustrating its internal structure.
Solution Approach:
1.
Understand the Structure of the Earth:
- The Earth is divided into several layers, including the crust, mantle, outer core, and inner core.
- Each layer has specific characteristics and sub-layers:
-
Crust: The outermost layer, which is thin and solid.
-
Mantle: The layer beneath the crust, divided into upper and lower mantle.
-
Outer Core: A liquid layer surrounding the inner core.
-
Inner Core: The solid center of the Earth.
2.
Analyze the Diagram:
- The circular diagram on the left shows a simplified view of the Earth's layers.
- The cross-sectional diagram on the right provides more detailed information about each layer and sub-layer.
3.
Match Labels with Terms:
- Use the descriptions and positions of the layers in the diagrams to match the numbers with the correct terms.
Step-by-Step Matching:
#### Circular Diagram (Left):
-
1: This is the outermost layer, which is the
Crust.
-
2: This is the layer beneath the crust, which is part of the
Upper Mantle.
-
3: This is the layer below the upper mantle, which is the
Lower Mantle.
-
4: This is the central red region, which is the
Core. It can be further divided into the outer core and inner core.
#### Cross-Sectional Diagram (Right):
-
5: This is the outermost layer, which is the
Crust.
-
6: This is the layer directly beneath the crust, which is the
Lithosphere (Crust + Uppermost solid mantle).
-
7: This is the
Upper Mantle, which includes the asthenosphere.
-
8: This is the
Asthenosphere, a part of the upper mantle that is semi-fluid.
-
9: This is the
Lower Mantle, which is solid.
-
10: This is the
Outer Core, which is liquid.
-
11: This is the
Inner Core, which is solid.
Final Matching:
-
1: Crust
-
2: Upper Mantle
-
3: Lower Mantle
-
4: Core
-
5: Crust
-
6: Lithosphere
-
7: Upper Mantle
-
8: Asthenosphere
-
9: Lower Mantle
-
10: Outer Core
-
11: Inner Core
Final Answer:
\[
\boxed{
\begin{array}{ll}
1 & \text{Crust} \\
2 & \text{Upper Mantle} \\
3 & \text{Lower Mantle} \\
4 & \text{Core} \\
5 & \text{Crust} \\
6 & \text{Lithosphere} \\
7 & \text{Upper Mantle} \\
8 & \text{Asthenosphere} \\
9 & \text{Lower Mantle} \\
10 & \text{Outer Core} \\
11 & \text{Inner Core} \\
\end{array}
}
