Based on the provided diagram and instructions, here is the solution to the task:
The goal is to interpret the diagram of Earth's interior by identifying the Asthenosphere and Stiffer Mantle layers and then highlighting their corresponding properties on the adjacent graphs.
1. For the Asthenosphere (Plastic Mantle) Layer:
*
Location: The Asthenosphere is clearly labeled in the main diagram as the layer situated directly beneath the Lithosphere and above the Stiffer Mantle.
*
Density Range: To the right of the Asthenosphere label, the corresponding density range is explicitly given as
3.4–5.6 g/cm³.
*
Pressure Graph: The pressure graph shows pressure increasing with depth. The portion of the curve "under the Asthenosphere" corresponds to the depth range where this layer exists. On the graph, this is the section of the curve that starts just below the surface (where the Lithosphere ends) and extends down to the boundary with the Stiffer Mantle. This is roughly the part of the curve from a pressure of approximately 0.5 million atmospheres up to about 2.5 million atmospheres.
*
Temperature Graph: Similarly, on the temperature graph, the portion of the curve under the Asthenosphere corresponds to its depth range. This is the section of the curve that begins at the top of the mantle (just below the crust) and continues down to the top of the Stiffer Mantle, showing a steady increase in temperature from around 1000°C to approximately 2000°C.
2. For the Stiffer Mantle Layer:
*
Location: The Stiffer Mantle is labeled in the main diagram as the layer located directly beneath the Asthenosphere and extending down towards the core.
*
Density Range: To the right of the Stiffer Mantle label, the corresponding density range is explicitly given as
5.9–12.2 g/cm³.
*
Pressure Graph: The portion of the pressure curve "under the Stiffer Mantle" corresponds to its depth range. This is the section of the curve that starts at the bottom of the Asthenosphere (around 2.5 million atmospheres) and continues down to the top of the outer core. This represents a steep increase in pressure, from about 2.5 million atmospheres to over 3 million atmospheres.
*
Temperature Graph: On the temperature graph, the portion of the curve under the Stiffer Mantle corresponds to its depth range. This is the section of the curve that begins at the bottom of the Asthenosphere (around 2000°C) and continues down to the top of the outer core, showing a continued but less steep increase in temperature, reaching approximately 3500°C.
In summary, to complete the task, you would:
- Color the Asthenosphere layer on the main diagram with a brown pencil.
- Highlight the density range of 3.4–5.6 g/cm³ on the density graph.
- Highlight the corresponding section of the pressure and temperature curves for the Asthenosphere's depth.
- Color the Stiffer Mantle layer on the main diagram with a yellow pencil.
- Highlight the density range of 5.9–12.2 g/cm³ on the density graph.
- Highlight the corresponding section of the pressure and temperature curves for the Stiffer Mantle's depth.
