Answer 1

Each term matches to a specific layer of Earth's interior: the lithosphere is the layer between the crust and the asthenosphere, the asthenosphere is the semi-solid layer beneath the lithosphere, the crust is Earth's outermost layer, the lower mantle surrounds the inner core, the upper mantle is between the asthenosphere and lower mantle, the outer core is the liquid layer responsible for Earth's magnetic field, and the inner core is the solid metallic center.

Step-by-step explanation:

The correct matches for each term to its description based on the structure of Earth's interior are as follows:

1. Lithosphere: the firm layer between the crust and the asthenosphere.
2. Asthenosphere: the semi-solid layer between the top layer and the upper mantle.
3. Crust: the Earth's outermost layer.
4. Lower Mantle: the layer surrounding the inner core.
5. Upper Mantle: the layer between the asthenosphere and lower mantle.
6. Outer Core: the hottest part of the mantle.
7. Inner Core: the metallic layer at the Earth's center.

Note: The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid, while the asthenosphere is the partially molten upper mantle material below it. The inner core is the dense, solid center of the Earth, and the outer core is the liquid layer that surrounds the inner core and is responsible for the Earth's magnetic field. The crust is the thin, outer surface layer, and the mantle is divided into the upper and lower mantle, based on depth.
