Which weather change is most likely indicated by rapid falling air pressure

Base your answer on the weather map below, which shows the locations of a high-pressure center (H) and a low-pressure center (L) over a portion of North America. The isolines indicate surface air pressures.

The arrows on which map show the most likely path in which these two pressure centers will move over the next few days?

Which map shows the most likely location of clouds associated with these pressure centers?

Which map best represents the surface wind pattern associated with high-pressure and low-pressure systems in the Northern Hemisphere?

An air mass entering Alaska from the northern Pacific Ocean would most likely be labeled on a weather map as

Jet stream winds over the United States generally move from

Base your answer on on the station models below, which show various weather conditions recorded at the same time on the same day at four different cities.

Which city had the lowest relative humidity?

What is the dewpoint temperature when the relative humidity is 30% and the air temperature is 20°C?

Base your answer on the map below, which shows sea-level air pressure, in millibars, for a portion of the eastern coast of North America. Points A, B, C, and D are sea-level locations on Earth's surface.

Which location most likely recorded the highest wind speed?

Which list shows atmospheric layers in the correct order upward from the Earth's surface?

Why are carbon dioxide and water vapor called the greenhouse gases?

Which weather-station model shows an air pressure of 993.4 millibars?

Base your answer on the weather map below. The map shows a low-pressure system and some atmospheric conditions at weather stations A, B, and C.

Which cross section best represents the air masses, air movement, clouds, and precipitation occurring behind and ahead of the warm front located between stations A and B?

Base your answer on the graph below which shows the changes in relative humidity and air temperature during a spring day in Washington, D.C

What were the relative humidity and air temperature at noon on this day?

Base your answer on the cross section below and on your knowledge of Earth science. The cross section shows the general movement of air within a portion of Earth's atmosphere located between 30° N and 30° S latitude. Numbers 1 and 2 represent different locations in the atmosphere.

Which map best shows the surface movement of winds between 30° N and 30° S latitude?

Base your answer on the weather map below and on your knowledge of Earth science. The weather map shows a typical low-pressure system and associated weather fronts labeled A and B. The L indicates the center of the low-pressure system. A few New York State cities are shown. Symbols cP and mT represent different air masses. The wind direction at Utica and Rochester is shown on the station models.

Which front symbols are drawn correctly, based on the air masses shown?

Which cross section best represents a cold front?

The map below shows air pressures recorded in millibars (mb).

Which map shows the correct location of the 996-mb, 1000-mb, and 1004-mb isobars?

The station model below shows some weather conditions at a location on Earth's surface.

Which present weather symbol represents the most likely type of precipitation occurring at this location?
