Magma and it’s evil ways
Common elements/where they came from Even though there are 92 elements that are naturally found,
only eight of them are common in the rocks that make up the Earth’s outer layer, the crust. Together, these 8 elements make up more than 98% of the crust.
The 8 most common elements in Earth’s crust (by mass): 46.6% Oxygen (O)27.7% Silicon (Si)8.1% Aluminum (Al)5.0% Iron (Fe)3.6% Calcium (Ca)2.8% Sodium (Na)2.6% Potassium (K)2.1% Magnesium (Mg)
Objective 16.2 Explain how the three major rock types are
formed and how the rock cycle works
Key Ideas Define rock and mineral Types of rocks Rock cycle Weathering and erosion
Minerals: Naturally occurring, inorganic, solid element or
compound with a definite chemical composition or regular crystal structure
Analogy: batter, chocolate chips, nuts
Rocks
-solid, cohesive aggregate of one or more minerals
-3 types of rock
Analogy: a chocolate chip cookie with nuts
Three Types of RocksSedimentary
Igneous
Metamorphic

The Rock Cycle
The Rock Cycle
Weathering
Physical Weathering
Chemical WeatheringThe process of chemical weathering tends to increase bulk creating stress within rocks lower the density minerals decreased particle size resulting in increased
surface area creates more mobile materials creates more stable minerals
Erosion
Sedimentation
