Geology The study of solid Earth, the rocks of which it is composed, and the processes by which they change.
Why Evolutionists Study Geology The history and evolution of life and our climate, comes from the study of the geologic record. It includes the study of fossil life and physical changes to the Earth Changes include: movements of continents; formation and reconfiguration of ocean basins; growth of mountain ranges; erosion and redistribution of sediments; changes in surface environments; and changes in climate over time.
Layers of Earth Core Mantle Crust Including the asthenosphere Three major concentric zones of the earth Core Mantle Including the asthenosphere Crust Continental crust Oceanic crust: 71% of crust
Major Features of Earth’s Crust and Upper Mantle
The Earth Beneath Your Feet Is Moving!! Convection cells, or currents Tectonic Plates Lithosphere
The Earth’s Major Tectonic Plates
The Earth Beneath Your Feet Is Moving!! Three types of boundaries between plates Transform Plates: Lateral sliding Effect: lithosphere neither created nor destroyed Divergent plates: Spreading Effect: oceanic lithosphere created Ex: Oceanic ridge Convergent plates: Subduction Effect: oceanic lithosphere destroyed Ex: Trench
Where are each type of boundary?
The Earth Beneath Your Feet Is Moving!! Ex: Transform fault; e.g., California San Andreas fault
