Step-by-step solution for: Earth Systems Worksheet - WordMint
Let's solve this Earth Systems matching worksheet step by step. We'll match each numbered definition with the correct term from the list on the right (A–S). Here's a clear explanation for each:
---
1. The soft layer of the mantle on which the lithosphere floats.
→ S. Asthenosphere
*Explanation:* The asthenosphere is a semi-solid, ductile layer in the upper mantle that allows the rigid lithospheric plates to move above it.
---
2. The mixture of gases that surrounds Earth; the outermost of the four spheres into which scientists divide Earth.
→ O. Atmosphere
*Explanation:* The atmosphere is the layer of gases surrounding Earth, including nitrogen, oxygen, and trace gases.
---
3. All living things; one of the four spheres into which scientists divide Earth.
→ E. Biosphere
*Explanation:* The biosphere includes all living organisms on Earth—plants, animals, microorganisms—and their environments.
---
4. The transfer of heat by movements of a fluid.
→ C. Convection
*Explanation:* Convection is the process where heat is transferred through the movement of fluids (liquids or gases), such as in the mantle or atmosphere.
---
5. Earth's dense center made up of the solid inner core and the molten outer core; also the central.
→ F. Core
*Explanation:* The core is Earth’s innermost layer, composed of iron and nickel, divided into solid inner core and liquid outer core.
---
6. The layer of the rock that forms Earth's outer surface.
→ J. Crust
*Explanation:* The crust is the thin, outermost solid layer of Earth, varying in thickness between continental and oceanic areas.
---
7. A rigid layer made up of the uppermost part of the mantle and crust; one of the four spheres into which scientists divide Earth.
→ B. Lithosphere
*Explanation:* The lithosphere includes the crust and the uppermost rigid part of the mantle. It breaks into tectonic plates.
---
8. Earth's water and ice; one of the four spheres into which scientists divide Earth.
→ P. Hydrosphere
*Explanation:* The hydrosphere includes all water on Earth: oceans, lakes, rivers, glaciers, groundwater, and atmospheric water vapor.
---
9. A rigid layer made up of the uppermost part of the mantle and crust; one of the four spheres into which scientists divide Earth.
→ B. Lithosphere
*Note:* This is the same as #7. Likely a duplicate question. Answer remains B. Lithosphere.
---
10. The layer of hot, solid material between Earth's crust and core.
→ L. Mantle
*Explanation:* The mantle lies beneath the crust and above the core. It's composed of solid rock but behaves plastically over long timescales.
---
11. The substance or substances of which any physical object consists or is composed.
→ A. Matter
*Explanation:* Matter refers to anything that has mass and takes up space, such as rocks, water, air, etc.
---
12. A natural resource that is not replaced as it is used. Non-Renewable
→ M. Resources
*Wait — this seems misaligned.*
Actually, "Non-Renewable" is a descriptor, not a term. But looking at the options, G. Resources is likely meant to be matched with this, though the phrasing is odd.
But note: There are two “Resources” entries — G and M. That may be a typo.
However, G. Resources probably refers to non-renewable resources. So:
→ G. Resources
*(But better clarification: “Non-renewable resources” is the concept, so G is best fit here.)*
---
13. The process by which plants use water plus carbon dioxide and energy from the sun to make food.
→ N. Photosynthesis
*Explanation:* Photosynthesis converts light energy into chemical energy using CO₂ and H₂O to produce glucose and oxygen.
---
14. A resource that is naturally replaced in a relatively short time. Renewable
→ M. Resources
*Again, “Renewable” is a category. But since both G and M are “Resources,” likely M. Resources is intended for renewable resources. Alternatively, if there were a separate term like “Renewable Resource,” it would be clearer. But based on options, M. Resources fits best.*
*Alternatively, if we interpret the answer choices strictly, perhaps the term is missing. But given the context, M. Resources is the closest.*
---
15. A natural or artificial lake that stores water for human use.
→ D. Reservoir
*Explanation:* A reservoir is a body of water stored for human use, such as drinking water, irrigation, or hydroelectric power.
---
16. The combined processes, including photosynthesis, decomposition, and respiration by which carbon as a component of various compounds cycles between its major reservoirs—the atmosphere, oceans, and living organisms. Carbon
→ H. Cycle
*Explanation:* This describes the carbon cycle, a biogeochemical cycle involving the exchange of carbon among Earth's spheres.
---
17. A method of research in which a problem is identified, relevant data are gathered, a hypothesis is formulated from these data, and the hypothesis is empirically tested. Scientific
→ Q. Method
*Explanation:* This is the scientific method, a systematic approach to inquiry.
---
18. A region that is isolated from its surroundings by a boundary that admits no transfer of matter or energy across it. Closed
→ R. System
*Explanation:* A closed system does not allow transfer of matter (but may allow energy). However, the description says *no transfer of matter or energy*, which defines an isolated system. But since “Isolated” isn’t an option, and “Closed” is mentioned, the best match is R. System — but note: “Closed system” is the specific type.
Given the choices, R. System is the most appropriate general term.
---
19. Open system: a material system in which mass or energy can be lost or gained from the environment. Open
→ R. System
*Explanation:* Again, “open system” is a type of system. Since “System” is the only available term, R. System fits.

- Some terms are repeated (e.g., “Resources” appears twice — G and M), possibly a duplication.
- “Open” and “Closed” systems are types of systems, so R. System is the best choice for both 18 and 19.
- For #12 and #14, the descriptions are definitions of *types* of resources, so they map to Resources (G or M), but the exact term is missing. Likely, the intention was to use G. Resources for non-renewable and M. Resources for renewable — but without distinct labels, we assume G and M are interchangeable or duplicated.
