About Weather The Big Ideas

• Weather is the state of the atmosphere at a
  specific time and place.
• Weather includes temperature, air pressure,
  humidity, wind speed, and precipitation.
• Changes in air pressure are associated with
  changes in weather.
• Air movement is caused by the uneven heating of
  the Earth by the sun.
• The movement of air is wind as the air moves from
  one area to another.

About Climate The Big Ideas

• Climate is the average weather at a location over
  a period of years.
• Climate includes seasonal temperatures, winds,
  and average annual precipitation.
• Movement of water in the water cycle affects
  climate.
• Latitude and proximity to large bodies of water
  or mountains affect climate.

The Water Cycle The Big Ideas

• The sun provides the energy that drives the water
  cycle.
• When liquid water is warmed, it evaporates and
  turns into water vapor, a gas that enters the
  atmosphere.
• Water vapor can become liquid water or ice as it
  cools.
• Water vapor that has turned to liquid water or
  ice falls as precipitation.
• Water falling from the sky collects in bodies of
  water on the surface of the Earth as well as
  underground.

The Cycle of Day and Night The Big Ideas

• Earth rotates on its axis once every 24 hours,
  causing the cycle of day and night.
• When it is day on the side of Earth facing the
  sun, it is night on the other side.
• Earths rotation makes it appear that the sun,
  planets, and stars are orbiting Earth once a day.

Our Star, the Sun The Big Ideas

• The sun produces heat and light that travel to
  Earth.
• The sun is a star, one of billions in the
  universe.
• The sun is an average-size star.
• The sun is mostly hydrogen and helium.

Physical Characteristics of the MoonThe Key
Ideas

• Marias are seas of ancient basaltic lava flows
  that form plains on the moon.
• Highlands are the older, heavily cratered,
  mountainous areas of the moon.
• Regolith is the mixture of fine dust and rocky
  debris that forms the moons soil.
• The moon is divided into three distinct layers
  core, mantle, and crust.
• The far side of the moon is more heavily cratered
  because lava flows have covered many older
  craters on the near side, creating the maria.
