Surface water, including rivers, lakes, and wetlands, is the primary source of freshwater for ecosystems.

Water conservation helps in preserving ecosystems by reducing pollution, maintaining biodiversity, and preventing soil erosion.

Deforestation leads to decreased water retention, increased soil erosion, and deteriorated water quality.

Evaporation is the process by which water changes from a liquid to a gas and enters the atmosphere.

Wetlands help in flood control, groundwater recharge, and provide habitat for wildlife. They do not contribute to increased water pollution.

Precipitation is the process by which water vapor in the atmosphere condenses and falls to the Earth's surface.

Climate change, population growth, and industrialization are all major contributors to water scarcity.

Transpiration is the process by which plants release water vapor into the atmosphere through their leaves.

Drip irrigation is a water-efficient irrigation method that delivers water directly to the roots of plants, minimizing evaporation and runoff.

The water cycle, also known as the hydrological cycle, is the continuous movement of water between the Earth's surface and the atmosphere.

Over-extraction of groundwater can lead to land subsidence, saltwater intrusion, and depletion of aquifers. It does not improve water quality.

Condensation is the process by which water vapor in the atmosphere changes to a liquid and forms clouds.

Rainwater harvesting helps in reducing flooding, recharging groundwater, and improving water quality.

Evaporation is the process by which water changes from a liquid to a gas and enters the atmosphere.

Water pollution leads to eutrophication, habitat destruction, and health problems. It does not increase biodiversity.
