NGSS.MS-ESS2-3

plate boundary where two plates move away from each other.

• convergent

• transform

• divergent

theory that states that Earth’s lithosphere is made up of huge plates that move over the surface of Earth

• Theory of Plate Tectonics

• Big Bang Theory

• Theory of continental drift

NGSS.MS-ESS2-3

a section of lithosphere that moves over the asthenosphere carrying pieces of continental and oceanic crust.

• fault

• plate

NGSS.MS-ESS2-3

where the edges of two or more tectonic plates meet

• hot spot

• plate boundaries

• rift valley

 a gap at divergent boundaries where molten material rises to build new crust.  This can be at oceanic (mid-ocean ridges) and continental (volcanoes, lakes, rivers) 

• deep ocean trench

• mid-ocean ridge

• rift valley

heat from a plume (heated rising rocks in asthenosphere) melts some of the rock in the tectonic plate above – can cause volcanoes to form

• hot spot

• mid-ocean ridge

• rift valley

NGSS.MS-ESS2-1

 a long narrow trench when one plate goes under another at a convergent boundary

• hot spot

• deep ocean trench

• rift valley
