The theory that the earth is broken into plates and are in motion due to convection currents in the asthenosphere (upper mantle).
outer core
inner core
plate tectonics
continental drift
The thin and solid outermost layer of the Earth.
outer core
inner core
mantle
crust
This layer of the Earth is made from liquid iron and nickel. Motion in the liquid generates electrical currents. They, in turn, generate Earth’s magnetic field.
outer core
inner core
mantle
crust
The edges formed by the collision of two plates.
divergent boundary
convergent boundary
subduction
continental drift
The edges between two tectonic plates that are moving away from each other.
divergent boundary
convergent boundary
subduction
continental drift
A layer inside a planetary body bounded below by a core and above by a crust. It is made of molten (liquid) rock and is generally the largest and most massive layer of the planetary body.
outer core
inner core
mantle
crust
This solid metal ball has a radius of 758 miles, or about three-quarters that of the moon. This is Earth’s deepest layer.
outer core
inner core
mantle
crust
Process in which two plates collide and the denser plate descends below the other.
divergent boundary
convergent boundary
subduction
continental drift
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
