the earth's rigid crust and top of the mantle that sits on the athenosphere
the earth's softer rock that sits below the lithosphere and convects
a process where heating from below and cooling from above cause a liquid rise and fall in a circular motion
the amount of matter in a certain amount of space (mass per unit volume)
the earth's layer consisting of a ball of hot solid metals at the center of the earth
the earth's layer consisting of liquid metals that surrounds the inner core
the earth's thickest layer that sits above the outer core and consists of molten rock
the earth's layer that consists of cool rock on the outside of the earth
broken up pieces of the lithosphere that move due to convection
areas where heated rock rises in thin columns to form a volcano that can rise above the surface of the water (Ex. Hawaii)
huge underwater mountain ranges where tectonic plates move away from each other
Plate Tectonic Theory
the theory that states the Earth's lithosphere is made up of huge plates that move over the surface of the earth
a boundary that occurs where tectonic plates are pushing together
a boundary that occurs where tectonic plates are moving apart
a boundary that occurs where tectonic plates are sliding past one another
thicker, less dense crust that goes on top of oceanic crust when they converge
thinner, more dense crust that goes under continental cruse when they converge
one tectonic plate going under another tectonic plate (typically oceanic crust going under continental crust)
two continental plates collide, forming mountains
an oceanic plate collides with a continental plate causing the subduction to the oceanic plate
