The exchange of carbon within the spheres of the Earth.
Carbon Cycle.
Organisms that can survive without Oxygen.
Anaerobic Organisms.
Shows the true color of the mineral.
Color
Difference between Cleavage and Fracture
Cleavage has patterns; can only break in patterns
Fracture has irregularities; no patterns
If the minerals turns into powder
Brittleness
Two stages of Carbon Cycle.
Photosynthesis and Respiration.
Movement of phosphorus within the soil, water, and other organic materials.
Phosphorus Cycle.
Color of the mineral in powdered form
Streak
The ideal shape of crystal faces.
Crystalline structure or habit
Can be flattened
Malleability
Oxygen Cycle.
4 Stages in the Phosphorus Cycle.
1) Releasing of phosphate ions
2) Absorb the inorganic phosphate
3) Mineralisation
4) Soil phosphorus may gradually become part of the Sediments
Resistance to scratching
Hardness
Ability to allow light to pass through
Diaphaneity
Can be stretched to wire
Ductility
The four events happening in an Oxygen Cycle.
Photosynthesis, Respiration, Decomposition, Rusting.
Makes up the rocks beneath your feet; Building blocks of rocks.
Example: Graphite (pencils), Quartz (Glass), Feldspur (Porcelain)
Minerals
The scale that rates the hardness of minerals by their ability to scratch softer minerals.
Mohs Hardness Scale
Shows how light is reflected on the surface
Flexible but inelastic
Organisms that need Oxygen.
Aerobic Organisms.
Name the 5 Characteristics of a Mineral.
1. Naturally occuring
2. Inorganic
3. Homogenous solid minerals should have definite volume and rigid shape
4. Definite chemical composition
5. Orderly crystalline structure
Mineral's resistance to being broken and fracture.
Cleavage
Reaction of the minerals to stress
Can be bent and back to their original position/shape
Flexible and elastic
