Any water that falls from the sky (rain, snow, hail, sleet)

Pellets of frozen precipitation that fall from clouds

A single piece of hail

What the air is like due to temperature, wind, humidity, etc.

Stickiness in the air caused by high levels of water vapor in the atmosphere.

Distance from the ground.

Gas layer around the Earth that controls temperature.

Measure of how hot or cold the air is.

Amount of light from the sun to a specific place.

Amount of light that bounces off the ground and back to the atmosphere.

Amount of light the ground keeps that increases its temperature.

Unit of measurement for how much light hits a surface.

Amount of space an object takes up.

Amount of matter (stuff) in an object.

States that mass and matter cannot be created or destroyed.

The relationship between an objects mass and volume.

The transfer of heat from one object to another through collision or contact.

A very small amount (or single piece) of matter

A small volume of air used to model how air moves in the atmosphere.

A measurement of how much water vapor is in a part of the air.

Changing of a liquid into a gas. One of the stages of the water cycle.

Changing of a gas into a liquid. One of the stages of the water cycle.

The temperature at which a liquid begins to change to gas. For water, the boiling point is 212 degrees Fahrenheit or 100 degrees Celsius.

The temperature at which a liquid begans to change to a solid. For water, the freezing point is 32 degrees Fahrenheit or 0 degrees Celsius.

The process of gases or particles moving from the atmosphere to the surface of the Earth.

Tiny particles of things in the atmosphere (dust, smoke, salt) that allow water vapor to condense onto them to make clouds.

An area where atmospheric pressure is higher than the areas around it. This causes air to sink, light winds, and clear skies. Usually connected to stable weather conditions.

An area where atmospheric pressure is lower than the areas around it. This causes bad weather such as rain, clouds, and wind.

An upward force on air particles that makes them rise. Typically caused by warm, less dense air being lifted by cooler, more dense air.

The amount of force of the air on the surface of the Earth.

An instrument that measures atmospheric pressure.

The force that pulls all objects towards the center of the Earth.

The movement of heat and moisture in the atmosphere.

A liquid or gas tht can flow and match the shape of a container.

A steady flow of air or water in a specific direction.

A column of air that moves down quickly, usually tied to precipitation.

A small-scale current of rising air.

A tropical storm with constant winds of at least 74 miles per hour.

A predicton of the waether conditions for a specific time and location.

A large body of air with the same level temperature and humidity.

Border between two separate air masses with different temperatures and humidities.

The long-term pattern of weather in a specific area.

Hot, wet, and humid locations with little to no dry season (lots of annual rainfall, stable temperatures, and high humidity).

A climate with high levels of precipitation in the form of rain or fog, moderate temperatures, and regular seasons (but little temperature changes between summer and winter).
