Chapter 4 Flashcards
What Dissolves in the hot water to form solutions
Minerals
What is water heated by
Magma
What leaves the solutions during cooling?
Elements and compounds
What do elements and compounds do when they leave
Crystallize as minerals
The minerals form a long channel or slab in the rock called a
Vein
What are the two ways minerals form
- crystallization of melted materials.
2. crystallization of materials dissolved in water.
How do small crystals form
Fast cooling
How do big crystals form
Slow cooling
How do minerals for pm near ocean ridges
- Water seeps down through cracks in crust.
- water meets magma and cools to high temperature.
- water dissolves minerals from crust rushes up through chimneys.
- when cooled minerals crystallize they settle to the ocean floor
How do halite deposits form
When the ancient seas slowly evaporate
What is a mixture of one substance dissolves in another
Solution
What is a narrow channel of slab of a mineral that is sharply different from the surrounding rock.
A vein
Name all 5 mineral properties
- hardness
- color
- streak
- luster
- density
- crystal systems
- cleavage and fracture
- crystal systems
What is cleavage
The property of splitting across even surfaces
What is streak
The color of a minerals powder
What is a luster
How a mineral reflects light from its surface
What is a Compound
Two or more elements chemically joined
What is fluorescence
The property of glowing under ultraviolet light.
What is fracture
How a mineral breaks apart when it does not split evenly
What is the MOHs hardness scale
Ranking of minerals from softest to hardest
What is a crystal
The repeating pattern of a mineral particles in a solid
What is a element
A substance composed of a single type of Atom
What is a mineral
Naturally occurring inorganic solid that has a crystal structure and definite chemical composition
What does inorganic mean
Not Formed from living things or the remains of living things.
What is a crystal
A solid in which the Atoms are arranged in a pattern that repeats again and again
What is a element
A substance composed of a single kind of atom
What is a compound
A substance in which two or more elements are chemically joined
What is the Mohs hardness scale
Scale ranking minerals from the softest the hardest use them testing the hardness of minerals
What is a streak
The color of a mineral powder
What is a luster
The way a mineral reflects light from its surface
What is a fracture
The way mineral looks when it breaks apart in the regular way
What is cleavage
And minerals ability to split easily a long flat surfaces
What is florescence
The property of a mineral and watch the middle glows under ultraviolet light
What is a solution
A mixture in which one substance is dissolved in another
What is a vein
And narrow slab of a mineral that a sharply different from the surrounding rock
