Study Notes
Earth Layers and Atmosphere
- Earth consists of multiple layers: crust, mantle, outer core, and inner core. The troposphere is not a layer of the Earth itself.
- Inner core is solid due to extreme pressure, raising the melting point of its nickel and iron composition.
- Temperature decreases with altitude in the troposphere, impacting climatic conditions when climbing mountains.
- Nitrogen is the most abundant element in the Earth's atmosphere, followed by oxygen and argon.
- Atmospheric layers from bottom to top are: troposphere, stratosphere, mesosphere, thermosphere, exosphere.
- The ozone layer in the stratosphere provides protection from harmful UV rays, critical for life on Earth.
Tectonic Plates and Weathering Processes
- Tectonic plate boundaries include convergent, divergent, and transform, but not insurgent.
- Physical weathering includes causes like wind, running water, and plant growth; chemical weathering is caused by acid rain.
- Erosion is the process of carrying small rock particles and soil to new locations.
- New sand in deserts is created through wind erosion of rocks.
Minerals and Their Properties
- A mineral is defined as a solid natural material with a crystalline structure.
- Key mineral properties: hardness, luster, streak, and cleavage.
- Streak is tested by rubbing a mineral on a tile, indicating its color when powdered.
- Known minerals include salt, while glass, steel, and sugar do not qualify as minerals.
Geological Processes
- Sedimentary rocks transform into metamorphic rocks under heat and pressure.
- Erosion and weathering are major causes of landscape changes, with moving water being the most influential.
- Mass wasting refers to downward movement of rock and soil under gravity's influence.
Earth's Historical Changes
- Pangaea was the supercontinent hypothesized to exist in Earth's early history.
- Alfred Wegener proposed the Theory of Continental Drift, explaining the formation of continents.
- Geological time periods include Mesozoic (breakup of land masses) and Cenozoic (uplifting of mountains).
Fossils and Natural Disasters
- Fossils are remnants of ancient organisms preserved in rocks.
- Natural hazards include tsunamis, earthquakes, and volcanic eruptions, while deforestation is a man-made issue rather than a natural hazard.
- Natural disasters cause significant damage to property and life, altering ecosystems.
Additional Terminology
- Denitrification releases nitrogen back into the atmosphere.
- Precipitation occurs when water droplets become heavy enough to fall from clouds.
- "Hades" is associated with concepts of hell in mythology, but in geology can refer to extreme conditions.
