Flashcards: Rocks & Minerals



                                  

Form a thin veneer over the continents
The kind of igneous rock that formed deep within the earth
Mud cracks
Intergrown crystals
The two characteristics used to classify igneous rocks
Fossils are found only in......
The physical properties of a mineral are determined by
Atoms arranged in a regular, repeating pattern
What Moh's scale measures
Distortion of structure
How clastic sedimentary rocks form
Solidification from molten rock
Ripple marks
The way a mineral reflects light
Heat and/or pressure
Texture of igneous rocks that have no crystal structure
The most abundant example of a silicate mineral
Color of a mineral in powdered form
Measures the resistance of a mineral
How non-crystalline minerals break
Another term for intrusive igneous rocks
Banding of minerals
Term describing sedimentary rocks formed from the cementation of particles.
Limestone and marble are examples of this category of rocks
Silicon-oxygen shape
Re-crystalization
How crystalline mineral break
Rocks such as limestone and dolostone which may form as seas evaporate
Igneous rock which form on the surface
The way some metamorphic minerals such as slate peel into layers as they weather
A naturally occurring substance with a definite chemical composition
The size of the crystals or particles in a rock
May form from the shells of marine organisms
