Study Notes
Earth's Interior
- Composed of several layers:
- Crust: outermost solid layer, ranging in thickness from 5-70 km
- Mantle: thick layer beneath the crust, divided into upper and lower mantle
- Outer Core: liquid iron-nickel alloy, responsible for generating Earth's magnetic field
- Inner Core: solid, iron-nickel alloy at the center of the Earth
Plate Tectonics
- Theory that explains the movement of Earth's lithosphere (outermost solid layer)
- Comprises 7 major plates and several smaller ones
- Plates move relative to each other, resulting in:
- Divergent motion: plates move apart, creating new crust
- Convergent motion: plates collide, resulting in subduction or collision
- Transform motion: plates slide past each other horizontally
Continental Drift
- Theory that continents have moved over time and were once joined together
- Evidence:
- Fit of the continents: puzzle-like fit of the continents
- Similarity of coastlines: identical rock formations and fossils on different continents
- Paleomagnetism: magnetism in rocks indicates continents have moved over time
Lithosphere
- Outermost solid layer of the Earth, comprising the crust and uppermost mantle
- Broken into several large plates that move relative to each other
- Thickness: varies from 50-200 km
GEMPA BUMI (EARTHQUAKES)
- Result from the movement of tectonic plates
- Occur when there is a sudden release of energy in the Earth's crust
- Types:
- Tectonic earthquakes: caused by plate movement
- Volcanic earthquakes: caused by volcanic activity
- Collapse earthquakes: caused by underground caverns or voids
GUNUNG BERAPI (VOLCANOES)
- Landforms that occur when magma from the Earth's interior rises to the surface
- Types:
- Shield volcanoes: gently sloping, formed by lava flows
- Composite volcanoes: steep-sided, formed by a combination of lava and ash
- Cinder cones: small, formed by ash accumulation
- Volcanic activity:
- Eruption: release of magma and gases from the Earth's surface
- Lava flow: molten rock that flows from a volcano
- Pyroclastic flow: fast-moving, hot cloud of ash and gas
