2.4 Movement of the Mantle and Lithosphere
subduction zone
The region where oceanic plates sink down into the asthenosphere.
convection cell
A circular pattern of air rising, air sinking, and wind.
mass
A measure of the amount of matter in an object
volume
A measure of the size of a body or region in three-dimensional space
divergent boundary
A plate boundary where two plates move away from each other
transform boundary
A plate boundary where two plates move past each other in opposite directions
convergent boundary
A tectonic plate boundary where two plates collide, come together, or crash into each other.
transform fault
Area where the earth's lithospheric plates move in opposite but parallel directions along a fracture (fault) in the lithosphere.
energy
Capacity to do work
kinetic energy
Energy of motion
work
Force x Distance
density
Mass / Volume
law of conservation of energy mass
Matter is not created nor destroyed in any chemical or physical change
radioactive decay
Release of nuclear particles and energy from unstable atomic nuclei
potential energy
Stored Energy
asthenosphere
Tectonic plates "float" on what layer
convection
the transfer of heat as a result of a mixing of a liquid or a gas
