Zorluk: KolayEarth's Interior and Plate Tectonics

Earth's interior is organized into distinct layers characterized by specific physical states and mechanical properties. Match each internal Earth layer to its defining physical characteristic.

  • CrustRigid, thin outermost solid rock shell forming both continents and ocean basins
  • AsthenosphereSemi-fluid, ductile region of the upper mantle that allows tectonic plates to move
  • Outer coreMolten liquid metal layer primarily composed of circulating iron and nickel
  • Inner coreExtremely dense, solid metallic sphere subjected to intense pressure at the center

Cevap

Crust matches with the rigid, thin outermost solid rock shell; Asthenosphere matches with the semi-fluid, ductile region of the upper mantle; Outer core matches with the molten liquid metal layer; Inner core matches with the extremely dense, solid metallic sphere at the center.
Earth's internal structure is divided by physical behavior: the brittle solid crust on top, the ductile plastic asthenosphere in the upper mantle, the liquid iron-nickel outer core, and the solid iron-nickel inner core.

Adım Adım Çözüm

1
Identify the state and location of the outermost layer
The crust is identified as the rigid, solid surface layer.
The crust forms the brittle outermost surface of the planet.
2
Identify the mechanical behavior of the upper mantle zone directly below the lithosphere
The asthenosphere is identified as the semi-fluid, ductile zone.
High temperatures make the rock ductile enough to flow slowly, carrying tectonic plates.
3
Differentiate the states of the metallic core layers
The outer core is liquid metal, while the inner core is solid metal.
Temperatures melt the outer core, but immense overburden pressure forces the inner core into a solid state.
