The map shows the path of a warm water surface current, labeled X.
What is X and what is its effect?
Gulf Stream & it brings a milder climate to the East Coast (NC coast) during winter months

• Heavy, constant winds
• Sudden hail
• Unstable atmosphere
Tornado

This source of heat energy circles planet Earth and has the hottest temperatures year round
equator
200
What measures the amount of rain an area receives?
Rain Gauge
200
How does the Sun’s energy impact the water cycle?
by providing heat that helps in evaporation
by giving light energy that helps condensation in plants
by providing gravity that helps in precipitation, resulting in flooding
by giving heat that helps melt the glaciers, resulting in transpiration
by providing heat that helps in evaporation
200
If warm air is less dense or lighter than cold air, does warm air rise or sink?
rises
300
This front forces rapid uplift of moisture, generating towering cumulus or cumulonimbus clouds, narrow bands of heavy rain showers or thunderstorms. Conditions typically clear rapidly once the front has passe
Cold Front
300
What direction does the Gulf Stream flow bringing warmer temperatures
North from the equator

A student makes a model of a wind vane with a pencil, pin, straw, and some paper cutouts. The direction the wind vane points when held outside is shown.
According to the wind vane, from which direction is the wind blowing?
The wind is blowing from the east.
The wind is blowing from the north.
The wind is blowing from the south.
The wind is blowing from the west.
The wind is blowing from the north.
300
When plants release water into the atmosphere
transpiration
300
Why at night, during a land breeze, is the water hotter than the land?
It takes water a longer time to cool down
400
This front brings long-lasting, steady rain, drizzle, or snow over a wide area and temperatures a rise steadily
Warm Front

What severe weather usually happens along the Gulf Stream in the warm Atlantic Ocean waters during late Summer and Fall
Hurricanes

This morning it was sunny. By lunch clouds started to cover the sky and the anemometer indicated and increase in wind speed. What type of air pressure would the barometer show?
In the morning, higher air pressure. By lunch, lower air pressure

In the water cycle
The addition of heat energy results in this process
The removal of heat energy results in this process
evaporation
condensation

A student in the Northern Hemisphere records weather data in an area for a day.
What season is it in the Southern Hemisphere?
Winter
500
This is caused by the uneven heating of the Earth’s surface by the sun and the resulting differences in air pressure
wind
500
Which city is more likely to have milder temperatures in January? Why?
Mebane
Charlotte
Wilmington
Wilmington because it is near the coast and the Gulf stream is a warm ocean current bringing milder temperatures to the coast
500
A hygrometer measures what?
The humidity or the amount of water vapor in the air
500
