El Ciclo del Agua

The Water Cycle

• The water cycle is a continuous process where water circulates between the Earth's surface and the atmosphere. This involves various stages: evaporation, precipitation, condensation, infiltration, and runoff (or surface runoff).

Evaporation

• Evaporation is the process by which liquid water changes to water vapor, mainly due to solar radiation.
• This vapor rises into the atmosphere.
• The rate of evaporation is influenced by factors like temperature, humidity, and wind speed.
• Increased temperature speeds up evaporation.
• Higher humidity reduces evaporation.
• Wind increases evaporation by carrying away the water vapor, preventing saturation and allowing more evaporation.
• Water bodies like oceans, lakes, and rivers are major sources of evaporation.
• Plants also contribute through transpiration.

Precipitation

• Precipitation occurs when water vapor in the atmosphere cools and condenses into larger droplets or ice crystals.
• These condensed particles become heavy enough to fall back to the Earth as rain, snow, sleet, or hail.
• The type of precipitation depends on the temperature profile of the atmosphere.
• Warm air can support rain, while colder air leads to snow or sleet.
• Temperature gradients are key to precipitation formation.
• Cloud formation and its type influence the form and magnitude of precipitation.

Condensation

• Condensation is the process where water vapor in the air changes back into liquid water.
• This occurs when the air cools down and the vapor molecules lose energy.
• Condensation is essential to cloud formation.
• Water vapor cools as it rises, and condensation forms clouds.

Infiltration

• Infiltration is the process where water on the ground surface enters the soil.
• The rate of infiltration depends on soil type, slope, vegetation cover, and rainfall intensity.
• Permeable soils allow more infiltration than impermeable soils.
• Vegetation cover can slow down surface runoff, increasing infiltration.
• Infiltrated water replenishes groundwater.

Runoff (Surface Runoff)

• Runoff or surface runoff is the flow of water over the Earth's surface.
• It occurs when rainfall or snowmelt exceeds the infiltration capacity of the soil.
• Runoff can lead to erosion and flooding.
• The rate of runoff is influenced by factors such as the intensity of rainfall. Topographical features like sloped land increase runoff.
• Impermeable surfaces like concrete and asphalt drastically increase runoff.
• Runoff transports eroded soil, pollutants, and other materials to rivers and streams, ultimately impacting water quality.

Summary of Interconnectedness

• The water cycle is a closed system, meaning water is constantly recycled.
• The various stages are interconnected. Evaporation fuels precipitation, and precipitation replenishes water bodies, groundwater, and soil moisture.
• Infiltration and runoff are competing processes that determine how much water drains to rivers and streams or seeps into the ground.
• Human activities, such as deforestation, urbanization, and land use change, can significantly impact the water cycle.
