| Earth Systems |
- Explain that air
surrounds us, takes up space, moves around us as wind, and may be measured
using barometric pressure.
- Identify
how water exists in the air in different forms (e.g., in
clouds, fog,
rain, snow and hail).
- Investigate
how water changes from one state to another (e.g., freezing, melting,
condensation and evaporation).
- Describe
weather by measurable quantities such as temperature, wind direction, wind
speed, precipitation and barometric pressure.
- Record
local weather information on a calendar or map and describe changes over a
period of time (e.g., barometric pressure, temperature, precipitation
symbols and cloud conditions).
- Trace
now weather patterns generally move from west to east in the United
States.
- Describe the weather
which accompanies cumulus, cumulonimbus, cirrus and stratus clouds.

| Processes That Shape
Earth |
- Describe how wind, water
and ice shape and reshape Earth's land surface by eroding rock and soil in
some areas and depositing them in other areas producing characteristic
landforms (e.g., dunes, deltas and glacial moraines).
- Identify and describe how freezing,
thawing and plant growth reshape the land surface by causing the
weathering of rock.
- Describe evidence of changes on
Earth's surface in terms of slow processes (e.g., erosion, weathering,
mountain building and deposition) and rapid processes (e.g., volcanic
eruptions, earthquakes and landslides).
