FORCES
The tendency of an object to resist a change in motion.
INERTIA
A wave that moves the medium at right angles to the direction in which the wave travels.
TRANSVERSE WAVE
The relationship between electricity and magnetism.
ELECTROMAGNETISM
The process through which oceanic crust sinks beneath a deep ocean trench and back into the mantle at a convergent plate boundary
SUBDUCTION
A rigid layer made up of the uppermost part of the mantle and the crust
LITHOSPHERE
The force that two surfaces exert on each other when they rub against each other
FRICTION
A wave that moves the medium in the direction parallel to the direction in which the wave moves.
LONGITUDINAL WAVE
A wave that is made up of a combination of a changing electric field and a changing magnetic field that can move through the vacuum of space
ELECTROMAGNETIC WAVES
A major belt of volcanoes that rims the Pacific Ocean
RING OF FIRE
The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
CONVECTION CURRENT
A measure of how much matter is in an object
MASS
A type of seismic wave that compresses and expands the ground
P WAVES
A trait that increases an organisms ability to survive and reproduce
ADAPTATION
A break in Earth's crust along which rocks move
FAULT
Small, solid pieces of material that comes from rocks or the remains of organisms and are deposited by erosion
SEDIMENTS
The measure of a force of gravity acting on an object.
WEIGHT
A type of seismic wave in which the shaking is perpendicular to the direction of the wave.
S WAVES
A coil of wire with a current
SOLENOID
The point on Earth's surface directly above an earthquake's focus
EPICENTER
An igneous rock that forms from lava on Earth's surface
EXTRUSIVE ROCK
The rule that in the absence of outside forces, the total of outside forces that interact does not change.
LAW OF CONSERVATION OF Momentum
MEDIUM
The material through which a wave travels
NATURAL SELECTION
The process by which organisms that are best adapted to their environment are most likely to survive and reproduce
RICHTER SCALE
FOSSILS
The preserved remains of traces of an organism that lived in the past
