Earth Science Review

Crust... 

• 2nd layer of Earth's makeup 
• Thick, liquid layer
• Thin, top layer of Earth
• a rock

Mantle 

• Thin, top layer of Earth
• 2nd layer of Earth with convection currents
• a rock
• Thick, totally liquid layer of Earth

core 

• The innermost layers of Earth
• Thin, outermost layer of Earth
• a rock 
• a solid geometrical form

Lithosphere 

• the part of earth made up of water
• the part of earth made up of rocks, minerals, and dirt
• a rock 
• water

outer core

• solid, innermost layer of earth
• a rock
• liquid layer surrounding the outer core
• the mantle

inner core 

• The innermost, solid layer of earth
• the liquid layer UNDER THE MANTLE
• a rock 
• the part of earth made up of water

tectonic plates

• a rock 
• a thick piece of crust floating on the mantle
• a thick piece of crust underneath the mantle
• transform boundry

continental drift 

• a rock 
• the lithosphere 
• the theory of convection currents in the crust 
• the theory that the continents can drift apart and have done so in the past

plate tectonics 

• the lithosphere 
• a rock 
• the theory that earth's lithosphere is divided into plates moving on the mantle
• the theory that the continents were once together

convergent boundary 

• a rock 
• plates coming towards each other 
• plates moving away from each other
• plates sliding against each other
