Glaciers store the majority of freshwater on Earth, followed by groundwater, lakes, and rivers.

Agricultural runoff, containing fertilizers and pesticides, is a major source of water pollution, contributing to algal blooms and eutrophication.

Water filtration involves passing water through a filter to remove particles, bacteria, and other contaminants.

Drip irrigation delivers water directly to the roots of plants, minimizing evaporation and water loss.

Evaporation is the process by which water changes from a liquid to a gas, moving from the Earth's surface to the atmosphere.

Dissolved oxygen is a measure of the amount of oxygen dissolved in water, which is crucial for aquatic life.

Agricultural runoff, containing excess nutrients, can lead to eutrophication, causing algal blooms and oxygen depletion.

Rainwater harvesting involves collecting and storing rainwater for various purposes, such as irrigation and household use.

Desalination is the process of removing salt and other minerals from saltwater to produce freshwater.

pH is a measure of the acidity or alkalinity of water, ranging from 0 to 14, with 7 being neutral.

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

Water-efficient appliances and fixtures reduce water consumption without compromising performance.

Water softening involves removing hardness minerals, such as calcium and magnesium, from water.

Turbidity is a measure of the clarity or cloudiness of water, caused by suspended particles.

Condensation is the process by which water vapor in the atmosphere condenses into liquid water, forming clouds.
