Cool air _____, becomes ________dense, and ______
Cool air RISES, Becomes MORE Dense and, SINKS
Use two descriptive words to describe the AIR behind a WARM front.
What is Warm, Less Dense, More Moist.
What is the color letter symbol for HIGH & for LOW PRESSURE SYSTEM used on a Weather Map?
What is a BLUE capital H
What is a RED capital L
What is Humidity?
What is the amount of water vapor (moisture) in the atmosphere.
Does a High-Pressure System bring POOR or GOOD weather? Why?
What is GOOD weather.
Because air molecules are sinking because they are Cooler, drier, and more dense.
Sinking air does not allow for cloud formation and precipitation
What is Conduction?
What is the transfer of heat from one substance to another.
Use two descriptive words to describe a COLD FRONT.
What is Cold, More Dense, More Dry
What is Weather?
Weather is the current (temporary) condition of the atmosphere, meaning what is happening outside your window right now.
What is Temperature?
Whatis the measure of how hot or cold something is by movement of energy.
Which days likely show a HIGH pressure system nearby?
Which days likely show a LOW pressure system nearby
What is Wednesday, Thursday, Saturday, Sunday.
Which surfaces on Earth warm quickly?
What is Sand, Rocks, Pavement, Soil, Ones without much plant life?
Why is precipitation occurring along this warm front?
Precipitation is occurring because warm air molecules are rising up and over the cold air.
In which direction does air move around High pressure system?
Air molecules go CLOCKWISE.
Describe what WIND is and what it does.
What movement of air molecules.
Wind is created because the air on earth is heated unevenly.
Warmer air (L) is LESS dense (LIGHTER) and cooler air is (MORE) dense (H).
Air wants to move from higher pressure to lower pressure.
Which days likely show a LOW pressure system nearby?
What is Monday, Tuesday, Friday.
Besides air what else on Earth experiences convection currents.
What is the Ocean.
Which pressure system involves SINKING air?
Which pressure system involves RISING air?
What is the pressure system involved with sinking air is High pressure.
What is the pressure system involving rising air is Low.
Name a couple of main weather conditions that could change drastically during a single day.
What is wind, temperatures, precipitations, cloud cover, humidity?
Today the weather is sunny and the skies are clear. What air pressures system moving in?
A high pressure system must have worked it way in.
What is the main cause of convection currents on Earth?
What is the uneven heating of Earth's surface by the Sun.
What is the main cause of convection currents on Earth?
What is the uneven heating of Earth's surface by the Sun.
Which air mass is advancing (moving in) cold or warm? What type of front would it form?
The air mass that is moving in is a WARM air mass. This would be a WARM front.
When a LOW pressure system is nearby, expect to have ______ weather.
When a HIGH pressure system is nearby, expect to have ______weather.
When a LOW pressure system is nearby, expect to have POOR weather.
When a HIGH pressure system is nearby, expect to have weather.
When looking at a weather map, where does precipitation usually occur?
Precipitation usually occurs along frontal boundaries (fronts) around the area of L (low) pressure.
Why does the air at higher pressure move downward?
Higher pressure areas have ' cooler' air associated with them.
Cool air is more dense than warm air, so the cool air will sink downward and away from the high pressure in a CLOCKWISE fashion.
