Study Notes

Water Distribution and Movement

Study of water's distribution and movement on Earth, including human impact on water availability.
Focus on both surface and underground water conditions.

Water Cycle (Hydrologic Cycle)

Continuous movement of water through solid, liquid, and gas phases.
Sun is the primary energy source driving the water cycle.
Bernard Palissy proposed the modern theory of the water cycle in 1580 CE.

Stages of the Water Cycle

Evaporation: Water from oceans, lakes, and streams transforms into vapor due to sunlight.
Transpiration: Plants release water vapor from leaves and stems into the atmosphere.
Sublimation: Snow can directly change into vapor without becoming liquid due to conditions like dry wind and low humidity.

Condensation Process

Water vapor in the atmosphere cools and transforms back into liquid, leading to cloud formation.
Sudden temperature drops can create fog when vapor condenses into tiny water droplets mixed with dust.

Precipitation

Wind causes cloud collisions resulting in rain, which replenishes Earth's water bodies.
In cold climates, water vapor can deposit as frost or snow, leading to accumulation in higher altitudes.

Underground Water Movement

Precipitated water infiltrates soil and rock layers, forming aquifers.
Earthquakes can help underground water reach the surface.
Volcanic eruptions mix underground water with surface water, continuing the cycle.

Key Impacts of the Water Cycle

Provides fresh water for plants, animals, and humans through groundwater purification.
Evenly distributes water across Earth's surfaces.
Temporary cloud storage and permanent reserves include rivers and lakes.
Evaporation causes a cooling effect, influencing weather and climate.
Supports other biogeochemical cycles like those involving oxygen and phosphorus.
Cleans the atmosphere by removing dust and bacteria, aiding air purification.

Human Impact on the Water Cycle

Deforestation: Disrupts water cycle flow by reducing groundwater levels and hindering transpiration.
Pollution: Air pollution from fossil fuels leads to smog and acid rain; agricultural runoff introduces chemicals, decreasing evaporation and condensation efficiency.
