Why do you see precipitation near the L? (select 2 answers)

• because that is low pressure and that is where air rises, forming clouds

• in Indiana

Multiple Choice

Tim said that Chicago is most likely to experience rainy weather. Jennifer thinks that Dallas is most likely to experience rainy weather.

Which student is correct?

• Jennifer because high pressure systems produce precipitation

• Both students are correct because all systems produce precipitation

• Neither of the students are correct because the cities are not close enough to the system.

Snow

A cold front from the north travels through
Albany, decreasing the air temperature.

A high-pressure system moves in from the
north, increasing the air pressure.

The precipitation along the cold front will pass through
Albany. (There is a shaded area just west of Albany on 1/18.)

The air temperature is below the freezing point (32 ℉),
causing the precipitation to be snow.

Multiple Choice

decreases.

⎯ Since warm air is less dense than cold air, it
rises over the cold air when they meet. The water
vapor in the air condenses as the air rises, forming
a cloud that can produce precipitation.
⎯ Precipitation falling from a cloud is formed by
warm air rising above cold air because warm air is
less dense. The water vapor in the rising air
condenses, forming a cloud.

⎯ Areas that receive more direct rays heat Earth’s surface, causing
warm air to rise, that eventually cools and falls toward Earth’s surface
at areas that receive less direct rays from the Sun.
⎯ Differences in air density are caused by unequal heating of Earth’s
surface. Warmer, less dense air rises (low pressure) and cooler, more
dense air sinks (high pressure).

Multiple Choice

The density of the air ______ as you go up in the atmosphere.

• increases

• decreases

• stays the same

⎯ The paths of winds on Earth’s surface are
curved because Earth rotates on its axis.
⎯ Earth is rotating, causing winds to curve.

Multiple Choice

Overcast skies & steady precipitation (snow or rain) is weather you'd see at what type of front?

• warm

• cold

Air temperature will increase because a
warm front will move into NY state.

⎯ It will decrease because warm air has lower air pressure
than cool air.
⎯ It will decrease because warm air from the warm front is less
dense and has lower pressure.
⎯ Warm air from the warm front will rise, causing a decrease in
air pressure.

Cloud cover will increase because clouds are presently
behind the warm front. When the front moves over NY State,
it will get cloudy.

⎯ Humidity will increase because clouds from the warm front
will enter New York State.

than in the middle of the country.

⎯ Oceans cause coastal climates to be generally
warmer in the winter than climates in the middle of
the United States, and coastal climates to be
generally cooler in the summer than climates in
