Study Notes
Geology
- Geology, also referred to as geoscience or earth science, means 'Study of the Earth.'
- Three major disciplines:
- Physical Geology: Focuses on earthquakes, volcanoes, Earth's history, and surface processes.
- Historical Geology: Analyzes fossil and rock records to understand past geological events.
- Environmental Geology: Examines the interactions between humans and their geologic environment, including the impact of human activities.
Climate
- Climate is defined as the long-term weather patterns in a specific area, typically assessed over 30 years.
- Weather can change frequently, from hours to years, but climate remains consistent compared to weather variability.
Topography
- Topography studies the physical features of land, including hills, valleys, and rivers.
- Derived from Greek, "topo" means "place," and "graphia" means "to write or record."
- Representations of topography are illustrated on topographic maps.
Biological Processes
- Biological processes refer to activities within organisms affecting their environment, including changes in seawater composition due to coastal organisms.
Groundwater
- Groundwater is water stored underground in soil, sand, and rock fractures, moving slowly through aquifers.
- Its level can fluctuate due to factors like heavy rainfall or groundwater extraction.
Aquifers
- Composed of permeable materials like gravel and sand that allow water to flow through connected spaces.
- The saturated zone is where groundwater is stored, with the water table marking its upper boundary.
Ice
- Ice is a solid state of water, usually pure but can contain trapped gases and particulates.
- Analysis of gases in polar ice caps provides insights into historical atmospheric composition.
Wetlands
- Wetlands are areas where water is present at or near the soil surface, supporting diverse biological communities including plants and animals.
Abiotic Factors
- Abiotic factors are non-living components of ecosystems, including water, air, soil, sunlight, and minerals.
- These resources are derived from the lithosphere, atmosphere, and hydrosphere.
Components of Environment
- The environment consists of all living (biotic) and non-living (abiotic) things, classified into four components:
- Hydrosphere
- Lithosphere
- Atmosphere
- Biosphere
Hydrosphere
- The hydrosphere encompasses all water on Earth, present in three physical states:
- Solid Water: Ice and snow found in polar regions and glaciers.
- Liquid Water: Present in oceans, rivers, lakes, and underground.
- Gaseous Water: Water vapor that exists in the atmosphere.
Distribution of Water
- 97% of Earth's water is saline (ocean), while only 3% is freshwater.
-
Freshwater Breakdown:
- 68.7% in glaciers and ice caps
- 30.1% as groundwater
- 0.3% surface water
- 0.9% out of reach
- Surface water consists of:
- 2% rivers
- 11% swamps
- 87% lakes
-
Freshwater Breakdown:
Biogeochemistry of the Hydrosphere
- Water quality in the hydrosphere varies based on factors like geology, climate, topography, biological processes, land use, and duration of water retention.
