What are the Physical Properties of Minerals?
• Luster • Hardness • Streak • Cleavage • Fracture • Color • Specific Gravity • Tenacity • Crystal Shape • Reaction to natural light

• Taste Test 2. Fizz Test
It is a precious metal which can be found pure in nature.
Gold
It is used as a catalyst in refining petroleum.
Platinum
What is the Rock Cycle?
Igneous → Sedimentary → ↑Metamorphic
What are the 3 major groups of rocks?
Igneous Rock, Sedimentary Rock, Metamorphic Rock
What are formed by the cooling and crystallization of hot, molten rock material called “magma”?
Igneous Rock
What does Igneous meam?
It means “formed by fire”
What does molten rock called when it reaches the surface?
“Lava”
The rocks resulting when lava is solidifies are classified as _____?
Extrusive Rocks
The magma does not reach the surface and crystallizes at great depths are called ______
Intrusive Rocks
Large intrusive rocks bodies are called _____
Plutons
Example of Igneous Rocks?
EX: andesite basalt granite diorite gabbro rhyolite
What forms when particles of other rocks or the remains of plants and animals ate pressed and cemented together?
Sedimentary Rock
What does Sedimentary mean?
derived from the word Sedimentation which means “settling”
What are the two classification of sedimentary rock?
• Clastic Sedimentary 2. Chemical Sedimentary
What sedimentary rocks that are formed by accumulation, compaction, and cementation of different solid particles that came from mechanical or chemical weathering?
Clastic Sedimentary
What sedimentary that mostly contains materials that are formed by chemical precipitation of minerals as a direct result of physical processes or as an indirect result of like process of water dwelling animals?
Chemical Sedimentary
Examples of Clastic Sedimentary?
conglomerate breccis sandstone limestone shale calcite halite
Example of Chemical Sedimentary?
calcite
