Geology Test Review

what happens to the temperature, pressure, and density as depth increases

• the temp increase and the rest stays the same

• they all decrease

• they all increase

• the temp decrease and the rest stays the same

earth's main layer that is made up of hot soften rock where convection currents occur

• crust

• mantle

• outer core

• inner core

this crust is less dense and is thick

• oceanic

• continental

• balsamic

• all of the above

this crust is thin and is more dense

• oceanic

• continental

• balsamic

• all of the above

earth layer that is rigid and brittle and houses the tectonic plates

• asthenosphere

• lithosphere

• mantle

• core

mantle layer that is plastic and flowing where convection currents occur

• asthenosphere

• lithosphere

• mantle

• core

scientist use these to determine the composition of earth's layers

• sonar waves

• sound waves

• seismic waves

• light waves

plate boundary moving together (collide)

• convergent

• divergent

• transform
