It is less dense than water.
Properties of Matter
Mass, Volume, Density
Mass divided by Volume
M / V
Metric unit for volume
Solid vs. Liquid
Which has the higher density?
The horizontal movement of air from an area of high pressure to an area of low pressure
Coriolis Effect
The way the Earth's rotation makes winds curve
Jet Stream
Bands of high speed winds located about 10 kilometers above Earth's surface
Ozone layer
Part of Earth's atmosphere that filters out the harmful rays of the sun
Part of the atmosphere on Earth where we live and where our weather occurs.
Carbon Dioxide
Causes heat to build up in the atmosphere.
Winds are named for the direction they are blowing to.
Gases in Earth's Atmosphere
Nitrogen 78% and Oxygen 21%
Causes of wind
Winds are caused by the sun heating the Earth differently around the world.
Movement of Air
Air tends to move from high pressure to low pressure areas.
Air flow near the water
During the day the air will flow from the sea to the land. At night, cooler air moves from the land to the sea.
Potential energy
The energy of position.
Example: Wound up spring or marble at the top of a ramp

The energy of motion.
Example: Moving car or boy running
Geothermal energy
Uses energy from inside the Earth.
Thermal energy
Heat energy which could be collected on solar panels.
Light energy
A photovoltaic cell (used on calculators)uses this type of energy from the sun to power the source.
