Harmful substances introduced into air, water, or land that can damage the health of people, animals, or plants.
Water that falls from clouds to Earth's surface, such as rain, snow, sleet, or hail.
A measure of how hot or cold something is.
A liquid made of hydrogen and oxygen that all living things need to survive.
Describes a substance with a pH below 7. This kind of water can be harmful in large amounts.
Describes a substance with a pH above 7 — another word for basic.
An underground layer of rock or soil that holds groundwater, often used as a source of drinking water.
The layer of gases surrounding Earth, held in place by gravity.
Describes a substance with a pH above 7 — the opposite of acidic.
The process of water vapor cooling and changing into liquid droplets, forming clouds.
The process of liquid water warming and changing into water vapor, rising into the air.
The solid surface of land that people and animals walk on.
The continuous movement of water between the atmosphere, land, and oceans, through evaporation, condensation, and precipitation.
Electricity generated using the force of moving or falling water.
All of Earth's water combined — oceans, rivers, lakes, ice, and groundwater.
The process of water soaking into the ground from the surface.
Describes a substance with a pH of exactly 7 — neither acidic nor basic. Pure water is a common example.
A measure of how easily water or other liquids can pass through a material.
Describes a material that allows water to pass through it.
A number that shows how acidic or basic a liquid is.
A measure of how much open space exists within soil or rock — more open space allows more water to be held.
Water collecting and standing on the surface instead of soaking into the ground.
Water that flows across the land's surface, eventually reaching rivers, lakes, or oceans, instead of soaking in.
A measure of how much salt is dissolved in water.
The outermost, top layer of something, such as land or water.
The process of a solid, like ice, changing directly into a gas without ever becoming a liquid.
An area of land where all the water — from rain, streams, and rivers — drains to the same larger body of water.
A measure of how clean and safe water is for people, animals, and plants to use.

Order the Water Cycle
Start with water, move it up (evaporation), cool it (condensation), drop it (precipitation), move it on land (runoff), soak it in (infiltration), store it (aquifer), and repeat the hydrologic cycle.
Reading
Water moves, changes, and collects on Earth. Warmth causes evaporation. Cooling makes condensation. Water falls as precipitation. Some flows as runoff. Some soaks in (infiltration) to the ground and aquifers. The hydrologic cycle repeats over and over.
Tip: Use the verbs move, change, collect to decide what happens earlier vs. later.
