Study Notes
Plate Tectonics
- Plate tectonics are driven by convection currents in the Earth's mantle.
- Hot magma rises, cools, and sinks, moving the plates.
- Earth's rotation is not the primary driving force.
Plate Boundaries
- Divergent boundaries: Plates move apart, creating new crust (e.g., mid-ocean ridges).
- Convergent boundaries: Plates collide, often forming mountains.
- Transform boundaries: Plates slide past each other (e.g., San Andreas Fault).
Minerals
- Calcite is a mineral composed of calcium carbonate (CaCO₃).
- It's a key component of limestone and marble.
Energy Resources
- Solar energy converts sunlight into electricity.
- Fossil fuels (coal, oil, natural gas) are formed from ancient plant and animal remains.
- Natural gas is the cleanest-burning fossil fuel.
Geological Processes
- Permineralization: Minerals replace organism structures, preserving them in rock.
- Sea-floor spreading: New oceanic crust forms at divergent boundaries as magma rises.
- Limestone is a sedimentary rock formed from compacted sediments (including shell fragments and calcium carbonate).
- The Earth's lithosphere is divided into tectonic plates.
