Anything that has mass and takes up space.
Matter
A force that occurs between two objects at a distance.
Non-contact force.
The stored energy that an object that is stretched or compressed.
Elastic potential energy
The rise and fall of ocean water due to the gravitational pull of the Sun and Moon.
Tides
The protection, preservation, and careful use of natural resources to prevent waste and ensure they last.
Conservation
Describes something that does not have a uniform structure or composition.
Heterogeneous
Forces acting on an object that are not equal; forces that cause a change in motion.
Unbalanced force
The stored energy of an object due to its height or position.
Gravitational potential energy
To move around another object.
Revolve
Contains all the living things on Earth.
Biosphere
A special group of metals found in Earth's crust that has unique properties
Rare Earth elements
The total force acting on an object.
Net force
Energy cannot be created or destroyed, only transformed.
Conservation of energy
Characterized by unusually high and low tides that occur during new and full moon phases.
A type of rock that forms forms magma or lava.
Igneous rock
The relationship between the mass and volume of an object or substance.
Density
The force that a surface applies to an object with which it is in contact.
Normal force
A type of wave where the particles of the medium vibrate perpendicular to the direction the wave travels.
Transverse wave
A season marked by increasing daylight hours and temperatures.
Summer
The layer of molten rock between Earth's crust and core.
The process where a substance is changed into a new substance with different properties.
Chemical reaction
A force of attraction between two bodies with mass.
Gravity
A type of wave where the particles of the medium vibrate parallel to the direction of the wave travels.
Longitudinal wave
An imaginary line around which an object rotates.
Axis
A type of rock that forms from intense heat and pressure.
Metamorphic rock
