Regents review set 2 Flashcards
(24 cards)
What happens to air pressure with altitude?
Air pressure decreases with altitude.
This is a fundamental concept in atmospheric science.
What type of wavelength does infrared have?
Infrared has long wavelength.
Infrared radiation is part of the electromagnetic spectrum.
In which direction does wind blow?
Wind blows from high to low pressure.
How is wind named?
Wind is named for the direction it is coming from.
What effect does the altitude of the sun have on shadows?
The lower the altitude of the sun, the longer shadows it casts.
Does porosity depend on particle size?
Porosity DOES NOT depend on particle size.
What causes wind?
Wind is due to air pressure differences.
How are air pressure differences created?
Air pressure differences are created by the unequal heating of Earth.
What happens to air pressure as temperature increases?
As temperature increases, air pressure decreases.
Describe high pressure systems and low pressure systems.
High pressure systems are cool and dry; low pressure systems are warm and wet.
What colors absorb and reflect energy?
Black absorbs / white reflects - Rough absorbs / smooth reflects.
Define conduction.
Conduction: molecule to molecule through collisions.
Define convection.
Convection: through fluids due to density differences.
Define radiation.
Radiation: through space.
How does energy move?
Energy moves from source to sink, high energy to low energy.
What is kinetic energy?
Kinetic energy: energy of motion; increases with velocity.
What is potential energy?
Potential energy: stored or at rest; increases with height.
Is there a temperature change during a phase change?
There is NO temperature change during a phase change.
What is the relationship between air temperature and dew point temperature?
The closer the air temperature is to the dew point temperature, the greater the chance of precipitation (higher RH).
What gases absorb infrared radiation?
Carbon dioxide (CO2) and water vapor (H2O) absorb infrared radiation.
What is the relationship between good absorbers of radiation and good radiators?
Good absorbers of radiation are good radiators.
What does Carbon 14 date?
Carbon 14 dates recent, once living objects.
What does Uranium 238 date?
Uranium 238 dates old rocks.
What happens to air pressure as moisture content increases?
As moisture content increases, air pressure decreases.
