The condition of Earths atmosphere at a particular time and place.
The envelope of gases that surrounds Earth.
A form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
Water in the form of a gas.
The amount of mass of a substance in a given volume.
The amount of force pushing on an area.

Elevation above sea level.
The lowest layer of Earths atmosphere Tropo- means to turn
The second-lowest layer of Earths atmosphere. Strato- means layered

Reflection of light in all directions.
The process by which heat is trapped in the atmosphere by gases that form a blanket around Earth.
A measure of how hot or cold an object is compared to a reference point.
The total energy of motion in the particles of a substance.
An instrument used to measure temperature.
The transfer of thermal energy from one object to another because of a difference in temperature.
The direct transfer of thermal energy from one substance to another that it is touching.
The transfer of thermal energy by the movement of a fluid.

The flow of cooler air from over an ocean or lake toward land.
The flow of air from land to a body of water.
Winds that blow steadily from specific directions over long distances.
The change that Earths rotation causes in the motion of objects and that explains how winds curve.

Bands of high-speed winds about 10 kilometers above Earths surface.
The continual movement of water among Earths atmosphere, oceans, and land surface through evaporation, condensation, and precipitation.
The process by which water molecules in liquid water escape into the air as water vapor.
The amount of water vapor in a given volume of air.
The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature.
An instrument used to measure relative humidity.
The process by which molecules of water vapor in the air become liquid water.
The temperature at which condensation begins.

Fluffy, white clouds, usually with flat bottoms, that look like rounded piles of cotton.
Clouds that form in flat layers and often cover much of the sky.
Any form of water that falls from clouds and reaches Earths surface.
Long periods of low precipitation.
An instrument used to measure precipitation.
