| Term | Definition |
|---|---|
| Air pressure | The measure of the force with which air molecules push on a surface |
| Barometer | An instrument that measures atmospheric pressure |
| Altitude | The height of an object above a reference point |
| Greenhouse Effect | The process by which gases are trapped and hold heat in the atmosphere like a blanket wrapped around the Earth |
| Anemometer | Measures wind speed |
| Continental Polar | A cold air mass that forms over land and that had low humidity |
| Continental Tropical | A warm air mass that forms over land and that has low humidity |
| Maritime Polar | A cold air mass that has high humidity as a result of passing over warmer water |
| Maritime Tropical | A warm and humid air mass that typically forms over tropical oceans |
| Temperature | A measure of how hot or cold a substance is |
| Cumulus | A low-level, billowy cloud that commonly has a top that resembles cotton balls and a dark bottom |
| Cirrus | A feathery cloud that is composed of ice crystals and that has the highest altitude of any cloud in the sky |
| Stratus | A gray cloud that has a flat, uniform base and that commonly forms at very low altitudes |
| Global Winds | Winds that blow steadily from specific directions over long distances |
| Coriolis Effect | The curving of the path of a moving object from and otherwise straight path due to the Earth's rotation |
| Local Winds | Winds that blow over short distances |
| Land Breeze | Flow of air from land to a body of water |
| Sea Breeze | Wind that blows from an ocean or lake onto land |
| Weather | The condition of the Earth's atmosphere at a particular time and place. It can change day to day |
| Pressure | Force pushing on an area |
| Density | The amount of mass in a given amount of volume |
| Radiation | Heat transfers through empty space |
| Conduction | Heat transfers by direct contact |
| Convection | Heat transfers by heated gas |
| Winds | The horizontal movement of air from an area of high pressure to an area of low pressure |
| Wind Vane | Tells wind direction |
