Study Notes

The Hydrosphere

Refers to all water present on or around Earth's surface, encompassing oceans, lakes, rivers, and atmospheric water.

Water Cycle

Describes the continuous movement of water on Earth, influenced by processes like evaporation, condensation, and precipitation.

Solvent

A liquid capable of dissolving other substances (solutes) during chemical processes.

Aquifer

Underground rock formations storing significant water resources essential for human use and consumption.

Watershed

Area of land that collects and drains surface water into bodies of water when soil saturation occurs.

River Basin

Land area drained by a river and its tributaries, vital for water flow and ecological health.

Ground Water

Covers underground water sources that are crucial for drinking and other uses.

Estuary

Coastal area where freshwater from rivers meets and mixes with saltwater from oceans; a diverse habitat influenced by tides.

Upwelling

Occurs when surface waters are displaced, allowing nutrient-rich water to rise from deeper layers, enhancing marine productivity.

Turbidity

Measurement of water clarity, indicating the presence of suspended particles or sediments, affecting aquatic life.

Potability

Indicates the suitability of water for human consumption, influenced by quality and contaminants.

pH

Scale from 0 to 14 identifying acidity or alkalinity; essential in assessing water chemistry.

Acid

Any substance with a pH lower than 7, typically characterized by a sour taste and potential corrosiveness.

Base

Substances with a pH above 7, often with a bitter taste and slippery feel, commonly used in various applications.

Dissolved Oxygen

The amount of oxygen present in water, crucial for aquatic life survival and ecosystem health.

Salinity

Measurement of salt concentration in water, influencing organisms' survival and habitat distribution.

Water Treatment

Processes aimed at purifying water to remove contaminants, ensuring it is safe for human use and consumption.

Stewardship

Responsibility of conserving and protecting valuable natural resources, including water, for future generations.

Shore

Marine ecosystem shaped by tidal movements, hosting species adapted to fluctuating conditions and diverse habitats.

Open Ocean

Expansive marine ecosystem relying on algae as primary producers, playing a key role in global oxygen production.

Deep Ocean

Marine ecosystem characterized by reliance on chemical energy sources, independent of sunlight, supporting unique life forms.
