C
Warm air rises because it is
less dense than cold air
High pressure is associated with what type of weather?
Fair/good weather
A warm front is a boundary where
warm air moves in over a cold air mass
Wind is the movement of air from areas of
high pressure to areas of low pressure
Which type of air front occurs when cold and warm air masses meet, but neither is moving?
Stationary front
Rain, snow, and hail are all examples of
precipitation
Convection currents, resulting from uneven heating of the Earth's surface, cause ______ to form.
Wind
The Gulf Stream is a current that brings warm ocean water from the south to the north. What type of heat transfer is this?
Convection
The atmospheric conditions that prevail from season to season and year to year at a certain location
Weather is best defined as
the condition of Earth's atmosphere at a particular time and place
An "L" on a weather map refers to
an area of low pressure
Where does the initial source of energy come from that creates winds and thus surface currents?
The sun
The Sun strikes the Earth the most at the Equator and the least at the poles. This causes warm air to _______ from the Equator and cold air to ________ at the poles.
Rise, sink
What is in the initial source for global winds and convection in the atmosphere?
Unequal heating of the Earth by the Sun
Draw the symbol for a stationary front
A line with triangles and circles pointing in opposite directions
Compared to the air at the poles, the air at the equator is warmer and
less dense, creating an area of low pressure as it rises
A large section of air with the same temperature and moisture level is called
An air mass
Precipitation
A cold front moving into an area can bring what type of weather?
Clouds and precipitation
Two front lines on a map best show
boundaries between different air masses
Where does precipitation typically occur?
Where warm and cold air masses meet
The summers are hot and humid describes the weather or the climate of an area?
Climate
A weather map shows a cold front moving into an area. Over the next several hours, what changes would most likely be observed?
Falling temperatures, increasing clouds, and precipitation
An air mass forms over a certain area. Based on what you know about air masses, this air mass would have:
The same temperature and moisture level throughout
In a particular region, a change in climate would likely have a greater effect on organisms than a change in weather would. Why?
A change in climate affects an environment for a longer time than a change in weather does.
