Study Notes
Key Terms and Concepts
- Precipitation: Includes rain, snow, sleet, or hail that falls from clouds; crucial for Earth's water cycle.
- World Ocean: A vast, interconnected body of water covering 70% of Earth's surface; plays a vital role in climate regulation.
- Aerosols: Tiny liquid droplets suspended in the atmosphere; can affect weather and climate.
- Conduction: The transfer of heat between objects in direct contact; fundamental in heat exchange processes.
- Earthquake: Vibrations caused by the sudden movement along a fault line; significant natural occurrence with potential for destruction.
Atmospheric and Oceanic Layers
- Ionosphere: A layer in the lower thermosphere; important for radio communication.
- Deep Zone: The bottom layer of the ocean extending from the thermocline to the ocean floor; characterized by cold and dark conditions.
- Troposphere: Densest atmospheric layer; where weather occurs and most of Earth's air mass is found.
- Stratosphere: Above the troposphere; contains the ozone layer that protects life from harmful UV radiation.
- Mantle: The layer of Earth located between the crust and core; involved in tectonic activity.
Water Cycle and Features
- Evaporation: The process in which the sun heats liquid water, causing it to rise as water vapor; critical for the water cycle.
- Salinity: Refers to the total dissolved salts in ocean water; higher in seawater than in freshwater.
- Fresh Water Sources: Primarily found in ice caps and glaciers; essential for drinking and agriculture.
- Thermocline: The boundary layer between warm and cold water in oceans or lakes; influences marine life distribution.
- Surface Currents: Movement of ocean water driven by wind; affects climate and marine ecosystems.
Geology and Earth Processes
- Tectonic Plates: Large pieces of the lithosphere; their movements cause earthquakes and volcanic activity.
- Volcano: A mountain formed by magma; associated with tectonic movement.
- Fault: A break in the Earth's crust; can lead to seismic activity when stress is released.
- Erosion: Removal and transport of surface material by wind and water; shapes landscapes over time.
Environmental Dynamics
- Greenhouse Gases: Carbon dioxide is a significant greenhouse gas; contributes to global warming.
- Biosphere: The narrow layer of Earth that supports life; includes land, water, and the atmosphere.
- Energy Transfer Mechanisms:
- Radiation: Energy transfer through space without a medium.
- Convection: Heat transfer through air or liquid currents.
Miscellaneous Facts
- Seismic Waves: Energy released during an earthquake travels as these waves; critical for detecting and analyzing seismic activity.
- Salts in Ocean Water: Ocean water contains higher quantities of salts compared to freshwater; primarily sodium and chlorine.
- Closed System: Earth is mostly a closed system regarding matter; exchanges energy but not matter with outer space.
