A statement about what you think will happen, based on what you know.
Prediction
the amount of force on an area.
pressure
Summers in South Carolina tend to be very hot and humid!
Climate
Movements of water that circulate in the ocean caused by global winds are called
ocean currents
The amount of water vapor in the air.
Humidity
Information that has been collected
Data
What kind of weather can you expect from a high pressure system?
Clear skies, sunny weather.
It is sunny outside today, but cooler than it was yesterday.
Weather
How are convection currents formed in the air?
Warm air is less dense, so it rises. Cold air sinks and moves in to take the place of the warm air.
Any form of moisture that falls from the sky. (rain, snow, sleet, hail)
Precipitation
Average weather conditions for a region year after year. It's what we expect
Climate
What kind of weather can you expect from a low pressure system?
Stormy weather.
The Gobi Desert gets an average of 7.6 inches of rainfall a year.
Climate
The Sun heats the surface of Earth, and then that heat energy is ________________ to the________.
transferred, air
Equator
The 4 natural divisions of the year based on temperature and the amount of sunlight, caused by the tilt of the Earth
Seasons
When an air mass gets colder it becomes _______ dense, exerts more pressure, and____________
more, sinks
The state of the atmosphere over 30 years.
Climate
Convection currents, which affect weather and climate, are created by...
the uneven heating of Earth.
The process of a gas changing into a liquid is _________.
condensation
The current condition of the atmosphere. (what is happening out your window)
Weather
When an air mass gets warmer, it becomes ___________ dense, exerts less pressure, and ____________.
less, rises
Jenny's roof sprang a leak last week because of all the rain
Weather
Look at the map of South America. Buenos Aires and Capetown are approximately the same distance from the equator and are both located on the coast. How does the air temperature of Buenos Aires compare to the air temperature of Capetown? Why?
The air in Capetown is colder than Buenos Aires. At Capetown, only a little energy is transferred from the ocean to the air because the current is coming from the South Pole. At Buenos Aires, a lot of energy is transferred from the ocean to the air because the ocean current is coming from the equator.
What is the process in which water vapor changes directly into a liquid?
evaporation
