What type of weather could Zone B expect to see over the next 12 hours?

In which direction is the wind coming from in Pittsburgh? How do you know?

The fronts shown on the weather map are best described as (1)boundaries between different air masses(2)areas experiencing clear skies with light winds(3) boundaries between different wind belts(4) areas experiencing extremely warm air temperatures

Once air mass A reaches location B, the weather conditions at location B will most likely become

(1) warmer and drier (3) colder and more humid(2) warmer and more humid (4) colder and drier

WHY?

Explain why city A has clear sky conditions.

Which terms are both used to describe the weather?

(1)gravity and wind direction(2)groundwater and erosion(3) precipitation and runoff(4) air temperature and wind speed

WHY? Why are the other choices wrong?

Which term refers to the atmospheric conditions that prevail from season to season and year to year at a certain location?

(1) climate (3) equilibrium(2) weather (4) ecosystem

How are weather and climate different?

Most scientists agree that an increase in the amount of greenhouse gases entering Earth’s atmosphere causes

(1)a decrease in sea level(2)an increase in melting of polar ice caps(3) a decrease in average surface temperatures(4) an increase in crustal plate movement

WHY?

What was the probable amount of rainfall, in inches, for Waterbury, Vermont, for that year?(1) 35 (3) 37(2) 36 (4) 43

What type of weather would you expect to have if air mass 1 moved over your location?

Why is City C cooler than City B?

The arrows in the diagram below show the circulation of air on a sunny day.

The air circulation shown is caused by

(1)both hot air and cool air sinking(2)hot air sinking and cool air rising(3) both hot air and cool air rising(4) hot air rising and cool air sinking

Which statement would most likely be included in a news report about an approaching hurricane?

(1) Open the windows to equalize air pressure.(2) Install snow tires and check the antifreeze in the car radiator.(3) Evacuate low-lying areas near the coast.(4) Expect wind speed to decrease for the next several hours.

A satellite image of a hurricane helps weather forecasters to(1) warn residents of hazardous weather conditions(2) explain the effects of global warming on the ocean currents(3) predict the times of high tide and low tide(4) predict the total number of storms to occur in one year

Which factor has the greatest influence on the direction of air-mass A?(1) sea breezes (3) ocean currents(2) upper air currents (4) mountain barriers

The movement of an air mass over Earth’s surface causes(1) earthquake activity (3) global warming(2) local weather changes (4) ecological succession

A sudden change in the weather at a certain location is most likely caused by(1) the arrival of an air mass (3) a high ocean tide(2) a severe earthquake (4) an eclipse of the Moon

Earth’s weather is primarily caused by the

(1)drifting of Earth’s crustal plates(2)uneven heating of Earth’s surface(3) gravitational attraction of the Moon(4) changing distance between Earth and Sun

Explain in your own words the diagram to the right in terms of air pressure.

Why are the lines around a high further apart?What does that have to do with wind?What type of weather is associated with high pressure?

An instrument for measuring air pressure is a ______.A. thermometerB. barometerC. scaleD. meter stick

Air pressure and wind combine to cause some very dramatic events.Tornadoes, hurricanes, and thunderstorms are all powered by air pressure and wind. A hurricane for example, usually forms out over the ocean when a large area of the ocean water becomes warmer than usual. The heat causes the air pressure there to drop, and this causes both thunderstorms and strong winds to develop. This is the beginning of a hurricane. Strong, spiraling winds cause the hurricane to move and pick up more energy along the way. An area of high pressure called the Bermuda High often directs hurricanes towards the United States.
