Water Cycle
Draw and explain the parts of the water cycle. (evaporation, condensation, precipitation, and runoff)
evaporation – changing of a liquid to a gas
condensation – a gas turns into a liquid
precipitation – water falls from clouds as rain, snow, sleet, or hail
runoff – water that flows off the land into streams, rivers, lakes, and the ocean
What is weather?
The state of the atmosphere.
What causes hail to form in layers?
Sometimes wind blows raindrops back up into the freezing air above the clouds. As the ice is blown through the clouds many times, it forms layers.
What is a heavy rainstorm with thunder and lightning?
Thunderstorm
What is elevation
height above sea level
What powers the water cycle?
Energy from the sun.
Which instrument is used to measure air pressure?
Barometer
Describe stratus clouds.
Low level clouds.
Blanket the sky.
What is a rotating column of air that extends from the clouds?
Tornado
What is climate and what is most helpful when studying it?
Climate is weather patterns over a long period of time.
Average yearly temperature.
Where does the water cycle begin?
There is no beginning or end to the water cycle.
Water changes form but does not leave the cycle.
Which instrument is used to measure relative humidity?
Hygrometer
Describe cirrus clouds.
High level clouds that are usually thin, wispy, and white.
What is a tropical storm that has reached wind speeds of over 119 km per hour.
Hurricane
What is weather made up of?
Weather is made up of ALL the conditions in one place at a single moment.
Where is water when it is a gas?
Water exists as particles of water vapor in the air.
Imagine you are climbing a mountain, what happens to the air pressure as you move up the mountain?
The air pressure will decrease as you move up the mountain. Air particles are farther apart the higher they are in the atmosphere.
Describe altocumulus clouds
They are mid-level clouds that look like small puffy balls.The bottom of the clouds may look dark because it is difficult for sunlight to get through.
When do thunderstorms occur?
when fast moving cold air meets slow-moving warm air
What is latitude?
Distance from the equator.
What appears on grass after a cool evening?
Dew or frost
What measures wind speed?
Anemometer
How does fog develop?
What stage of the water cycle does fog develop in?
Fog develops as moist air comes into contact with colder areas over land.
Condensation.
What causes the eye of the storm?
The center of the storm is a low-pressure area and the hurricane winds spin inward toward the lower pressure.
Why do temperatures in temperate zones vary throughout the year?
Temperatures in temperate zones vary through the year because the sun is more direct in summer, causing higher temperatures, and less direct in the winter, causing lower temperatures.
