Water Cycle Overview

Water Cycle Overview

• The water cycle involves the movement of water from the ground to the air and back again, driven by evaporation, condensation, and precipitation.

Key Processes

• Evaporation: Liquid water heats up, transforming into gas (water vapor).
• Condensation: Water vapor cools and changes back to liquid, forming clouds.
• Precipitation: Liquid or solid water (rain, snow, hail) falls to the ground when clouds become heavy with moisture.

Energy Source

• The sun provides the energy needed for evaporation, initiating the water cycle.

Water Forms

• Water Vapor: The gaseous state of water formed during evaporation.
• Condensed Water: Collects in clouds before falling as precipitation.
• State of Form: Water changes between liquid, gas, and solid phases in the cycle.

Precipitation Types

• Forms include snow, sleet, rain, and hail.

Accumulation

• Precipitation gathers in bodies of water such as lakes, rivers, and reservoirs, replenishing water sources.

Water Sources

• Salt Water: Primarily found in oceans and brackish water.
• Fresh Water: Available from rivers, lakes, and reservoirs.

Impact of Pollution

• Water pollution, caused by substances like oil and fertilizers, reduces usable water and affects ecosystems.

Environmental Concerns

• Drought: Extended periods without precipitation lead to water shortages and environmental stress.
• Flood: Excessive rainfall can result in flooding, overwhelming land and water systems.

Conservation Practices

• Conservation involves using only necessary amounts of water to prevent waste and protect resources.

Temperature Significance

• 32 degrees Fahrenheit marks freezing temperatures, critical for understanding weather impacts on water.

Ground Water

• After precipitation, some water is absorbed into the ground, providing vital drinking water for plants and animals.
