Weather and the Air
100
Humidity is the amount of water vapor in the air. True or False?
True
100
Why can't you ask someone: What is the climate like today? What is the better question to ask?
Climate is measured over a period of time. The correct thing to ask someone is what is the weather like today.
100
What type of instrutment would you use to measure humidity, and what would be used to measure air pressure?
A hygrometer measures humidity and a barometer measures air pressure.
100
97% of Earth's water supply can be found where?
The oceans is where 97% of Earth's water supply is.
100
What are the types of precipitation?
The types of precipitation are rain, snow, sleet, and hail.
200
What is weather?
Weather is the state of the atmosphere at a certain place and time.
200
Why is it imporant to look at average temperature and precipitation when determining a place's climate?
Climate is the weather over a period of time. Determining the averages helps you see these aspects over a period of time.
200
What happens when air masses meet?
Air masses meet at fronts, causing unsettled weather and precipitation.
200
Water vapor condenses in order to form clouds. What does the water vapor condense onto?
Water vapor condenses onto dirt particles to form clouds.
200
What is the atmosphere?
The atmosphere is a layer of gases that wraps around Earth like a huge blanket.
300
What is evaporation?
It is the change from the liquid to the gaseous state.
300
What is the difference between weather and climate?
Weather is what is going on day to day in a particular area. Climate is the weather of a particular area over a period of time.
300
Describe how air masses affect weather in areas they pass over.
They change the temperature and humidity level. When different air masses meet, they form fronts, which oftern cause a change in weather, or even storms.
300
What are the four major pieces of the water cycle?
The four major pieces are evaporation, condensation, precipitation, and runoff.
300
Earth's atmosphere is made up of mostly what gas?
Nitrogen
400
What is the definition of the water cycle?
The water cycle is the constant movement of Earth's water from the surface to the atmosphere and back again.
400
Average temperature and precipitation are the key parts of every climate. What are the factors that affect temperature and precipitation?
The factors that affect temperature and precipitation are latitude, elevation, and nearness to large bodies of water.
400
What is the weather like when a warm front moves through?
The temperature gets warmer. There are thick, low clouds, and long periods of light rain.
400
What is the difference between evaporation and condensation?
Evaporation is the change from liquid to a gas. Condensation is the change from gas to liquid.
400
What are the properties of air?
The properties of air are temperature, humidity, air pressure and wind.
500
What is the definition of climate?
Clime is the pattern of weather over a long period of time.
500
Being near to a large body of water, like an ocean or a large lake, affects climate. Why does a large lake or ocean affect climate?
Water heats and cools more slowly than land, and also doesn't reach temperatures that are as extreme as those on land. So warmer or colder air from the water can slightly raise or lower the temperature of air above nearby land.
500
How is weather different when a cold front moves through?
The temperature gets colder. There are tall storm clouds and short but heavy showers.
500
Why is the water cycle important for the Earth?
It recycles all of Earth's water without it, Earth would run out of water.
500
Why does low air pressure often mean cloudy and rainy weather? Why would you see clear skies with high air pressure?
Areas of low pressure have rising air. If rising air is humid, the water vapor in it cools to form clouds. Clouds can produce rain. Areas of high pressure have sinking air. Clouds cannot form when air is sinking, therefore areas of high pressure have clear skies.
