The matter that we breathe, particles move freely and quickly:

The major gas of our atmosphere:

All the layers of gases surrounding the Earth:

This is the first layer of the atmosphere (0-10mi, 0-16km) - Contains animals, plants, mountains, weather & clouds

This is the emission of energy in the form of waves or particles through space or a medium

The device which measures the weight of air:

The leading edge of a body of warmer air, usually bringing light precipitation

The horizontal movement of air from areas of high pressure to areas of low pressure:

These are high altitude clouds resembling horse's tails:

The Earth's rotation affecting the direction of winds on the Earth:

These are whirling funnel shaped clouds that cause localized damage due to high winds

This is the fifth and outermost layer of the atmosphere from 370+mi/ 400+km. Contains the Van Allen radiation belts and satellites.

Waves that consist of electric and magnetic fields:

When light bounces off of an object an back to your eye:

Where energy is given off by one object and taken in by another:

A visible mass of condensed water vapor

These are large storm clouds with flat tops and dark gray bottoms that usually produce violent storms, including hail and tornadoes:

This is a large mass of light, warmer air moving in a counterclockwise direction that usually indicates poor weather:

This is a large mass of heavy, cooler air moving in a clockwise direction that usually indicates fair (sunny/cooler) weather:

These are puffy white clouds that usually indicate fair weather (sunny/ cooler)

This is a chart commonly used to graphically display both the annual average temperature and precipitation for a city or region:

This is the third/middle layer of the atmosphere (30-53mi/50-85km), which burns up meteors and contains the Aurora Borealis:

This is the second layer of the atmosphere (10-30mi/17-50km) that contains weather balloons, large jets, the ozone, and tops of cumulonimbus clouds:

Energy of motion:

These are flat, gray clouds that usually bring longer periods of precipitation:

This is the leading edge of a body of cooler air, usually bringing storms and heavy precipitation:

These are large tropical storms formed in the ocean that cause damage due to rain and high winds:

This is the leading edge of two weather systems meeting with little to no movement - usually produces prolonged, bad weather:

These are flat, gray clouds that are usually already producing precipitation and lightning

This is when a cold front overtakes a warm front:

These are narrow bands of high-speed winds:

This is the fourth layer of our atmosphere (53-370mi/ 84-400km), contains radio waves, Aurora Borealis, International Space Station, Ionosphere
