Water

Aquifer

A water-containing, underground layer of rock. Aquifer. An aquifer is like an underground sponge that stores and provides water.

Condensation

The process of a gas changing into a liquid is condensation. Condensation is when water vapor in the air cools down and turns into tiny droplets of liquid water.

Conservation

The careful management and use of resources. Conservation. In science, conservation means protecting and preserving natural resources and environments for future generations.

Evaporation

The top of liquid changing into a gas. Evaporation. Evaporation is the process where liquid turns into gas, usually from the surface.

Groundwater

Rain and melted snow that is stored in underground soil and rock. Groundwater. Groundwater is the water found beneath the Earth's surface in spaces between soil and rocks.

Ocean current

The movement of streams of ocean water. Ocean current. Ocean current is the continuous flow of water in the ocean, driven by wind, temperature, and salinity differences.

Precipitation

Water that falls to Earth in any form, like rain, snow, sleet, or hail. Precipitation. Precipitation is when water droplets in clouds become heavy enough to fall to the ground.

Reclamation

The process of cleaning and restoring a damaged ecosystem. Reclamation. In simple terms, reclamation is the act of making damaged land or ecosystems healthy and usable again.

Reservoir

A storage area for fresh water. Reservoir. A reservoir is a large natural or artificial lake used to store water for various uses like drinking, irrigation, or power generation.

Salinity

The amount of salt dissolved in water. Salinity. It is the measure of how much salt is present in a given amount of water.

Water cycle

The constant movement of water through Earth and its atmosphere, by evaporation, condensation, and precipitation. Water cycle. The water cycle is the process by which water circulates between the Earth's surface and the atmosphere.

Water table

The top surface of underground water. Water table. The water table is the upper level of groundwater in soil or rock, where the ground is saturated with water.

Water vapor

Water in the form of a gas. Water vapor. Water vapor is the gaseous state of water that is part of the water cycle.

Watershed

A land area from which water drains into a river system. Watershed. A watershed is the area of land where all the water flows into the same river or stream.
