SP.12.1 - The earth supports life; it is warmed by energy from the sun, we

breathe the air of its atmosphere, and depend upon the atmosphere for

rain and other precipitation.

SP.12.2 - Weather changes all the time; the surface of the earth is marked

by extreme differences in temperature, moisture, and winds

SP.12.3 - Severe weather can produce great damage.


SI.12.1 - Differential warming of the earth's atmosphere and bodies

of water causes differences in temperature, barometric pressure, and rates

of evaporation and condensation at different locations across the

earth's surface. These differences cause air and water to move, drive

the water cycle, and result in weather and climate.

SI.12.2 - Winds, clouds, and large masses of moving air contain different

amounts of moisture at different temperatures, affecting the earth's surface


SI.12.3 - Forecasting weather is important because much of what people

do is dependent on the weather.


SJ.12.1.1 - Solar energy interacting with atmosphere, water, and land creates

variations in temperature and pressure, producing regional and global

atmospheric circulation patterns as well as climatic regions varying

in size from the microclimates of a community to global climates.

SJ.12.1.2 - The earth's atmosphere has evolved over time.

SJ.12.2 - Global regions produce air masses that differ in temperature,

pressure and relative humidity. These masses interact in different ways

to produce frontal weather patterns which vary in their effect and intensity.

SJ.12.3 - Clouds can indicate whether the local atmosphere is stable or



SH.12.1 - The release, absorption, and reflection of heat and light energy

by the atmosphere, water, and land are major processes in the formation of

weather and climate.

SH.12.2 - The circulation systems of the ocean interact with those of the

atmosphere to produce complex patterns of weather and climate. These

patterns may be stable over short or long periods of time.

SH.12.3 - Predicting long range weather is very difficult.
