Atmosphere
| Weather | The condition of Earth's atmosphere at a particular time and place. |
| Atmosphere | The envelope of gases that surrounds Earth. |
| Water Vapor | Water in the form of a gas. |
| Density | The ratio of the mass of a substance to its volume. |
| Air Pressure | The pressure caused by the weight of a column of air pushing down on an area |
| Barometer | An instrument used to measure changes in air pressure. |
| Mercury Barometer | An instrument that measures changes in air pressure, consisting of a glass tube partially filled with Mercury, with its open end resting in a dish of Mercury |
| Aneriod Barometer | An instrument that measures changes in air pressure without using a liquid. |
| Atltitude | Elevation above sea level. |
| Troposphere | The lowest layer of Earth's atmosphere. |
| Stratosphere | The second-lowest layer of Earth's atmosphere. |
| Mesophere | The layer of Earth's atmosphere immediately above the stratosphere. |
| Thermosphere | The outermost layer of Earth's atmosphere. |
| Ionosphere | The lower part of the thermosphere. |
| Exosphere | The outer layer of the thermosphere. |
| Electromagnetic Waves | A wave that can transfer electric and magnetic energy through the vacuum of space. |
| Radiation | The transfer of energy by electromagnetic waves. |
| Infrared Radiation | Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves. |
| Ultraviolet Radiation | Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays. |
| Scattering | Reflection of light in all directions. |
| Greenhouse Effect | The trapping of heat near a planet's surface by certain gases n the planet's atmosphere. |
| Temperature | How hot or cold something is; a measure of the average energy of motion of the particles of a substance. |
| Thermal Energy | The total energy of all the particles of an object. |
| Thermometer | An instrument used to measure temperature. |
| Heat | The transfer of thermal energy from one energy from one object to another because of a difference in temperature. |
| Convection | The transfer pf thermal energy by the movement of a fluid. |
| Conduction | The transfer of thermal energy from one particle of matter to another. A method of charging an object by allowing electrons to flow by direct contact from one object to another object. |
| Convection Currents | The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another. |
| Wind | The horizontal movement of air from an area of high pressure to an area of lower pressure. |
| Anemometer | An instrument used to measure wind speed. |
| Windchill Factor | A measure of cooling combining temperature and wind speed. |
| Local Winds | Winds that blow over short distances. |
| Sea Breeze | The flow of cooler air from over an ocean of lake towards land. |
| Land Breeze | The flow of air from land to a body of water. |
| Global Winds | Winds that blow steadily from specific direction over long distances. |
| Coriolis Effect | The effect of Earth's rotation on the direction of winds and currents. |
| Latitude | The distance in degrees north or south of the equator. |
