The Water Cycle/Clouds
What does the sun do to water in the water cycle?
Causes the water to heat up and tur into water vapor
James observes a barometer on a clear day. The barometer shows that the air pressure is quickly dropping. What weather will most likely result from the drop in air pressure?
Cloudy and rainy
When it is summer in the northern hemisphere, it is winter in the southern hemisphere. Why would the northern and southern hemispheres have opposite seasons?
Earth's tilt and orbit around the sun
A cold front will move through Charlotte late Wednesday afternoon. Which type of weather conditions will Charlotte most likely experience during that time?
Warmer temperatures Tuesday, stormy weather late Wednesday, and cooler temperatures on Thursday
What is most likely to occur during a 24 hour weather cycle at the beach?
A change in wind direction
What type of weather would you expect to see with stratus clouds?
Mostly cloudy skies and a slight chance of precipitation
A scientist is collecting data over time using a barometer. What trends could best be revealed from the data?
changes in air pressure levels
Why does warm air rise and cold air sinks?
Warm air is less dense than warm air because the molecules aren't as tightly packed.
A cold front is expected to hit the area overnight. What will the weather be like during?
Cloudy skies, precipitation, decreased temperature
Throughout the year, there is usually some wind blowing at the beach during day and night. What is the cause of these winds?
The differences in the temperature of land and ocean
What must occur before clouds can form?
Transpiration or evaporation must add water to the atmosphere
What kind of air makes a low pressure system?
Warm air because it holds more humidity.
How are hurricanes and tornadoes related to air masses?
They form where air masses meet.
What usually happens when a warm front collides with a cold front?
Precipitation, stormy weather, increased temperatures
What are prevailing westerlies responsible for in the northern hemisphere?
Moving weather patterns from west to east
What type of clouds would a cold front most likely bring?
Cumulonimbus clouds
A weather system from the Gulf of Mexico brings heavy precipitation to an area. Which best describes the air mass?
A low pressure air mass
When the northern hemisphere (where we live) is tilted away from the sun, what season is it?
Winter
What is an occluded front and what type of weather occurs?
It is formed when a cold front overtakes a warm front and rain and thunderstorms can occur.
How could La Nina affect weather during the summer in North Carolina?
It could decrease rainfall
Jenn looked out her wind and saw cirrus clouds. What type of weather should she expect for the day?
Nice, fair weather
How does air pressure affect wind?
Air pressure causes wind to move from areas of high pressure to areas of low pressure.
If you were predicting a severe storm, which weather instruments would you prioritize?
Barometer-many weather occurrences are caused by the change in air pressure.
Explain what a weather front is.
A large air mass with the same temperature, humidity, and pressure
You live near a large body of water, and every morning, you notice that the air feels cooler near the shore compared to the land. By late afternoon, the temperature on land is much warmer than near the water. What weather phenomenon is causing this temperature difference?
A sea breeze
