Condensation | The process by which a gas changes to a liquid |
Precipitation | Water that falls from clouds to Earth |
Evaporation | The process by which liquid changes to a gas |
Water Cycle | The constant movement of water throughout the atmosphere |
Meteorologist | A person who studies weather |
Weather | The condition of the atmosphere at a certain place and time |
Air Mass | Large body of air with the same temperature and humidity |
Polar Climate | Climate that is very dry and cold |
Climate | The pattern of weather an area experiences over time |
Temperate Climate | A climate that changes with the seasons - like Georgia |
Current | A stream of water that flows through the ocean like a river |
Tropical Climate | Climate that is hot and rainy |
Cold Front | A cold air mass moves under a warm air mass, causing storms |
Cold Front Symbol | It is a blue line with blue triangles |
Meteorology | The study of weather |
Front | A place where two air masses meet |
Stationary Front | A front that is not moving either way |
Humidity | The amount of water vapor in the air |
Warm Front | When warm air moves over cold air and produces long-lasting rain |
Warm Front Symbol | It is a red line with red half circles |
What is a low air pressure system? | An air mass with low air pressure |
What kind of weather does a low pressure system bring? | It brings warm and rainy weather (low air pressure = less dense = warmer) |
What is a high pressure system? | An air mass with high air pressure |
What kind of weather does a high pressure system bring? | It brings cool and fair weather (high air pressure = more dense = cooler) |
In what direction does weather usually move across the United States? | West to East |
