Movement and storage of water between Earth’s atmosphere, hydrosphere and geosphere
Water Cycle
Molecule movement in liquids, solids and gases from slowest to fastest
Solid, liquid and gas
Water falling from sky including snow, sleet, hail and rain.
Water turning into a gas because of added heat energy
Water vapor condenses to form water droplets in the form of clouds
When water enters the soil & can be used by plants and animals or become part of the groundwater supply.
Plants releasing water vapor into the atmosphere
Hold water molecules together and cause water to flow freely.
Hydrogen Bond
Most abundant gases in atmosphere
Nitrogen and Oxygen
Instrument package that scientists use to gather data about the atmosphere. This helps forecast the weather.
Government agency that collects & analyzes weather and climate data in the United States.
The National Weather Service
Force of pressure exerted by air molecules over a part of Earth’s surface. Also called air pressure.
Atmospheric pressure
Measures air pressure
Low air pressures
High air pressures
Sunny skies
Air moving from place to place
Occurs in polar regions and blow east to west.
Polar Easterlies
Occurs between 30-60 degrees N and S latitudes. Blow west to east.
Occurs just above & below the equator. Blow east to west.
Trade Winds
Earth’s rotation causes winds that move East and West based on their point of origin on the surface.
Coriolis Effect
Wind Energy advantages
No pollution and wind is a renewable energy source.
Wind Energy disadvantages
Winds blow inconsistently, windmills are unsightly and rotating blades can kill birds.
Day-to-day changes in atmospheric conditions including precipitation, wind speed, wind direction, temperature, humidity, air pressure and clouds.
Rocks broken down over time as a result of weather
Averaged weather conditions in an area over a period of many years
Area on Earth with similar temperature and precipitation patterns
Climate Zone
Studies past weather records to determine patterns that may be helpful in predicting long-term future events.
Prediction of future weather events for specific locations
The collection, study, analysis and reporting of weather data.
Stages in a Thunderstorm
Developing stage, mature stage and dissipating stage.
Developing Stage
Warm moist air moves up into the atmosphere and forms a thunderstorm cloud when it hits cool air.
Mature Stage
Cloud grows and becomes too heavy to hold any more water so it precipitates and causes a downdraft.
Dissipating Stage
Storm starts to fade when all the precipitation is released and the downdraft is greater than the updraft.
Fast flow of electrical energy between two charged surfaces. (Usually between atmosphere and ground)
Cool, dry air meets warm, moist air and creates a thunderstorm. High winds in the upper atmosphere push against thunderstorm clouds and cause rotation in storm.
Formation of Tornado
Warm, moist air combines with light winds in high atmosphere. The disturbance can create a strong low pressure system. Need heated, moist air from ocean waters to continue developing.
Formation of Hurricane
What to do before, during and after a severe weather event takes place.
Weather Safety Plan
Transfer of energy through waves
Occurs when material is in direct contact with another material with a different heat energy.
When warm fluids rise and cold fluids sink
Energy budget that accounts for specific ways heat moves in and out of the atmosphere.
Energy Budget
When greenhouse gases trap solar radiation and maintain tolerable temperatures on Earth.
Greenhouse Effect
Changes in climate resulting from human activities.
Global Warming
Long and short term changes in Earth’s climate that result from natural processes as Earth’s multiple spheres interact with each other.
Global Climate Change
Contributes to Global Warming
Burning fossil fuels like coal, oil and natural gas.
