Study Notes
Earth's Layers
- Earth has a layered structure, including the crust, mantle, outer core, and inner core.
- These layers differ in composition and density.
Tectonic Plates and Theories
- Earth's lithosphere is divided into numerous tectonic plates.
- Plate tectonics theory explains the movement and interaction of these plates.
- Evidence for plate tectonics includes:
- Matching coastlines of continents.
- Distribution of fossils and rocks.
- Geological features like mountain ranges and volcanoes.
- Earthquakes and volcanoes occurring along plate boundaries.
Tectonic Plate Movement
- Plates move slowly over Earth's mantle.
- The movement is driven by convection currents in the mantle.
Three Tectonic Boundary Types and Their Interactions
- Convergent Boundaries: Plates collide, leading to mountain ranges, volcanoes, and deep ocean trenches. Different outcomes depend on the type of crust involved.
- Divergent Boundaries: Plates move apart, forming new crust, ridges and rift valleys.
- Transform Boundaries: Plates slide past each other, causing earthquakes.
Minerals
- Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystal structure.
- Minerals have unique properties, including:
- Color
- Hardness
- Cleavage
- Luster
Three Rock Types and Their Formation
- Igneous Rocks: Formed from cooled and solidified magma or lava.
- Sedimentary Rocks: Formed from the accumulation and cementation of sediments.
- Metamorphic Rocks: Formed from existing rocks changed by heat, pressure, or chemical reactions.
The Rock Cycle
- The rock cycle describes the continuous process of transformation between these three main rock types.
- Processes include weathering, erosion, melting, and solidification.
