What is an isotope?
An ion
Varieties of a given atom which are produced by variations in the number of neutrons in the nucleus
An element
Name the properties of a mineral
Occur naturally as as an inorganic solid
Has a specific internal structure
Has a chemical composition that varies within definite limits and can be expressed by a chemical formula
Has definite physical properties that results from its crystallization and composition
It is stable over a relative range of temperature and pressure
All of the above
What is an ion?
An isotope
the things that make up elements
Electronically charged atoms which are produced by the gain or loss of electrons
A molecule
A mineral is a naturally inorganic crystalline solid that is composed of a certain chemical composition
The two mineral groups are non silicates and silicates.
What is hardness?
A mineral's resistance to being stretched.
Moh's Hardness scale
Topaz
If a mineral has basal cleavage,how many cleavages does it have?
1
2
3
6
If a mineral has a planar cleavage, how many cleavages does it have?
4
If a mineral has a blocky cleavage, how many cleavages does it have?
What is a fracture?
When a mineral has no weaknesses in its internal structure
When a mineral has a weakness
What is an conchoidal fracture?
An uneven fracture
When a fracture produces smooth curved surface
What is internal energy driven by?
Internal energy is driven by radioactive material at the core mantle boundary (CMB), creates convections, which causes heat to move toward the surface. It drives plate tectonics
External energy
Plate tectonics
What is external energy driven by?
The sun
erosion
External energy is driven by the sun (Unequal heating of the earth) It reshapes the earth's surface to erosion
