Question Answer
Oceanic crust Made frozen oxygen, silicon and aluminum
Continental crust The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores.
Lithosphere The lithosphere Is made of two parts the crust and rigid upper part of the mantle. The solid part of the crust.
Outer core
Inner core
The asthenosphere is a plastic layer of the mantle it is made up of solid rock flows very slowly.Liquid like substance that is owwweeee and goeeee
Beneath the ansthenosphere is the strong lower part of the mantle called the meososphere. It is located bottom of the earths core.
Is the thickest than the crust and contains most of the earths mass.
The outer core of the earth is a fluid layer about 2,300 km (1,400 mi) thick and composed of mostly iron and nickel
The earths inner core is the earths innermost part. It is primarily a solid ball with a radius of about 1,220 kilometers.
Alfred Wagner The guy who invented the theory of Pangea
Continental drift A theory that the continents are slowly moving
Mid oceanic ridge A under water ridge that goes through the whole Ocean
Pangea The theory that the continents were together
Sea floor spreading Where new oceanic crust is formed through volcanic activity
Convection current A current fluid that results in convection
Plate boundary A tectonic boundary were two plates are moving away from each other
Convergent boundaries is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle.
Divergent boundary Where two plates are moving away from each other
Transform boundary Are places where two plates slide sideways for each other
Subduction Where one plate moves under each other
Theory about plate tectonics Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle
Volcano A volcano is a rupture in the crust of a planetary-mass object
Earthquake An earthquake is the shaking of the surface of the Earth
Hotspot hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared
