Study Notes
Types of Precipitation
- Rain comprises water droplets that provide freshwater to Earth.
- Snow is solid precipitation occurring at temperatures below 0°C, formed from ice crystals in cold, moist regions.
- Hail is solid precipitation in irregular lumps or balls of ice, typically 5mm to 15cm in size, mostly occurring during thunderstorms.
Infiltration
- Refers to the absorption of precipitation by soil, aiding groundwater replenishment.
Geosphere
- Represents the solid state of Earth, encompassing its structure, composition, minerals, and processes.
Lithosphere
- Composed of the rigid outermost part of the geosphere, divided into tectonic plates.
Tectonic Plates
- Rocky segments of lithosphere that drift approximately 1-16 cm annually, influencing geological activity.
Parts of Earth
- Crust: Outermost and thinnest layer, about 1% of Earth's volume, where life exists; temperature ranges from 200°C to 400°C.
- Moho: Boundary between crust and mantle, discovered in 1909; separates different seismic wave types (P-waves and S-waves).
- Mantle: Largest Earth layer by volume, 2,900 km thick with an average temperature of 3,000°C.
- Outer Core: A fluid magma-like layer, 2,890 to 5,000 km below the surface, responsible for Earth's magnetic field; temperatures range from 4,500°C to 6,000°C.
- Inner Core: Deepest layer made of iron and nickel alloy, average temperature 5,500°C; solid due to immense pressure from overlying layers.
Biosphere
- Integral subsystem encompassing all ecosystems on Earth; was defined by geologist Eduard Suess in 1875.
Earth Subsystems
- Earth is 4.56 billion years old and resides in the "Goldilocks Zone," suitable for life.
- Earth revolves around the Sun every 365-366 days.
Atmosphere
- Composed of gases surrounding Earth, held by gravity; consists of 78% nitrogen, 20.95% oxygen, 0.93% argon, and 0.04% other gases.
Layers of the Atmosphere
- Troposphere: Closest layer where weather occurs.
- Stratosphere: Contains the ozone layer.
- Mesosphere: Region where meteors burn.
- Thermosphere: Layer where satellites orbit.
- Exosphere: Boundary to the vacuum of space.
Atmospheric Circulation
- Process redistributing solar heat across Earth's surface, crucial for climate and weather patterns.
Earth’s Cycle
- The Earth system perpetually recycles material through overlapping cycles that sustain the planet.
