Here’s how to categorize each item based on physical and compositional layers of the Earth:
Physical Layers:
- Asthenosphere
- Mesosphere
- Outer Core (note: this layer not mentioned but important for physical layers)
- Inner Core (also not mentioned but relevant)
Compositional Layers:
- Crust
- Mantle
- Core
Now, let’s address the specific questions:
-
What layer is found at the Earth's center?
- Core
-
Which of the following of Earth’s layers is a liquid layer with the highest density?
- Outer Core
-
What is the composition of Earth’s core?
- Mostly iron
To summarize:
- Physical Layers: Asthenosphere, Mesosphere
- Compositional Layers: Crust, Mantle, Core
- Core is at the Earth's center.
- Outer Core is the liquid layer with the highest density.
- The composition of Earth's core is mostly iron.
