Unit 3 Vocabulary Study Game

Earth's thin, outer shell made up of low-density minerals called silicates. (Solid)

• Core
• Mantle
• Crust
• inner core 

Compositional layer below the crust containing minerals such as magnesium and iron. (Putty-like state)

• core 
• mantle
• crust
• asthenosphere

At the center of the Earth, contains the densest minerals. (liquid outer core and solid inner core)

• mantle
• crust
• core
• mesosphere

The outermost physical layer of the Earth. Top contains the crust and bottom contains the upper mantle.

• lithosphere
• mesosphere
• asthenosphere
• crust

Thin layer of mantle below the Lithosphere, putty-like state.

• lithosphere
• asthenosphere
• mesosphere
• core

The lower part of the mantle, beneath the asthenosphere.

• lithosphere
• mesosphere
• asthenosphere
• mantle

A wave of energy that travels through the Earth and away from an earthquake in all directions.

• seismic wave
• s-wave
• p-wave
• core

The hypothesis that today's continents were once part of a single landmass.

• continental drift
• plate tectonics
• subduction 
• sea-floor spreading 

The theory that Earth's outer layer is made up of large, moving pieces called tectonic plates. The theory explains how plates interact and how those interactions relate to processes such as earthquakes and mountain building.

• sea-floor spreading
• plate tectonics 
• continental drift
• subduction 

The process by which new oceanic lithosphere forms when magma rises to Earth's surface at mid-ocean ridges and solidifies, as older,existing sea floor moves away from the ridge. (Happens at divergent boundaries)

• subduction 
• plate tectonics
• sea-floor spreading 
• continental drift
