Properties of Air
Less dense; lower air pressure; rises
What is WARM AIR?
An area of sinking cool/cold air where air molecules are more dense
What is High Air Pressure?
Winds that travel over long distances in steady patterns over several weeks
What are GLOBAL WINDS?
Winds that can blow in any direction and travel over short distances
What are LOCAL WINDS?
HIGH Pressure zones located 30 degrees South and 30 degrees North
What are the HORSE LATITUDES?
More dense, higher air pressure, and sinks
What is COLD AIR?
An area of rising warm air where the air molecules spread out and are less dense
What is Low Pressure?
The pair of calm regions where there is little to no wind
What are the DOLDRUMS and the HORSE LATITUDES?
During the day at an ocean beach, a cool breeze blows from the ocean
What is a SEA BREEZE?
Horizontal movement of air that moves from an area of High Pressure to an area of Low Pressure
What is WIND?
Air over these surfaces heat up and cool down FASTER
What is LAND?
Mount Everest at 29,029 feet above sea level air pressure level
What is Low Pressure?
This global wind system blows cold, sinking air from Earth's poles towards the Equator
What are POLAR EASTERLIES?
At night on an ocean beach, a cool breeze blows from the land to the ocean
What is a LAND BREEZE?
LOW Pressure zones that are located near the Equator
What are the DOLDRUMS?
Movements of warm and cold air in a circular pattern of rising and sinking air
What are CONVENCTION CURRENTS?
On the shore of the Dead Sea 430 meters below sea level air pressure level
What is High Air Pressure?
Largest global wind belt where winds blow strong and steady from the East and travels from the Horse Latitudes to the Doldrums
What are the TRADE WINDS?
This breeze occurs at NIGHT when COOL Low Pressure air moves down the mountain to the Low Pressure valley below
What is a MOUNTAIN BREEZE?
Earth's tilt and the angle of the Sun's rays hitting the Earth are responsible for this
What is the UNEVEN HEATING OF EARTH?
Sunlight heats an area of ground that heats the air above it creating a __ Pressure area.
An area of ground that is NOT heated as much creates a __ Pressure area.
What is LOW PRESSURE AIR and HIGH PRESSURE AIR?
The air from a __ Pressure area rushes across the surface of Earth to fill a space left by a rising __ Pressure area
What is High Pressure and rising Low Pressure?
These global wind start at the Horse Latitudes and blow toward the poles and carry WEATHER across the U.S.
What are the WESTERLIES?
This breeze occurs during the DAY when the Sun heats up a mountain more quickly than the valley below
What is a VALLEY BREEZE?
Winds always blow from __ Pressure to __ Pressure
What is HIGH Pressure to LOW Pressure?
