Element

• a naturally occurring organic or inorganic material

• a substance that cannot be

  separated or broken down into simpler substances by

  chemical means

Atom

• an observed change in

  the frequency of a wave when the source or observer is

  moving

• deoxyribonucleic acid

• the smallest unit of an element that

  maintains the properties of that element

• in biology, the smallest unit that can perform all

Crystal

• a natural, usually inorganic solid

  that has a characteristic chemical composition and an

  orderly internal structure

• the maintenance of

  a constant internal state in a changing environment

• a force of attraction between objects

  that is due to their masses

• a solid whose atoms, ions, or

  molecules are arranged in a regular, repeating pattern

Streak

• the color of a mineral in powdered form

• multi-colored circular ark

Luster

• the way in which a mineral reflects light

• any material that attracts iron or

  materials containing iron

Cleavage

• in geology, the tendency of a mineral to split along specific planes of weakness to form smooth, flat surfaces

• the inward

  force required to keep a particle or an object moving in

  a circular path

• the thin and solid outermost layer of Earth above the mantle

• a method of sending information from place to place between

  people or animals

Weathering

• the natural process by which

  atmospheric and environmental agents, such as wind,

  rain, and temperature changes, disintegrate and

  decompose rocks

• the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure
