7.4 Earth's Three Layers
Terms in this set (12)
Layers of the Earth based on what they're MADE of - crust, mantle, core.
Layers of the Earth based on physical properties - lithosphere, asthenosphere, mesosphere, outer core, inner core.
The strong, lower part of the mantle between the asthenosphere and the outer core. Made of more solid rock
Pieces that make up the lithosphere (like puzzle pieces) that float on the Asthenosphere and allow continental movement.
The thinnest, outermost layer of the Earth made of ocean and land.
Layer between the crust and the outer core that is the majority of the Earth's mass. Made of two layers Asthenosphere and Mesosphere
Circulation currents in the Asthenosphere causing the movement of the tectonic plates.
The layer of the Earth below the mantle, but above the inner core - made of liquid iron and nickel.
The hottest and most dense innermost layer of the Earth made of solid iron and nickel. This layer stays solid due to the pressure of the layers above it.
Upper part of Mantle that is semi-liquid and flows like hot asphalt allowing movement of tectonic plates.
Outer part of the solid earth that is broken into tectonic plates.
Innermost layer of the earth made mostly of iron. Made up of the outer core and the inner core.
