Term
What is a description of atmospheric conditions over a long period of time?
Definition
Climate
Term
The bottom layer of the atmosphere in which we live is called the?
Definition
troposphere
Term
Which form of radiation has the longest wavelength?
Definition
red light
Term
This layer of atmosphere contains ozone that filters UV radiation
Definition
Stratosphere
Term
The average kinetic energy of all the atoms and molecules that make up a substance is referred?
Definition
Heat
Term
the two principle absorbers of radiation emitted by earth's surface are carbon dioxide and?
Definition
Water vapor
Term
On a map showing temperature distributions, what are the lines connecting points of equal temperature?
Definition
Isotherms
Term
Which gas is most abundant in clean, dry air?
Definition
Nitrogen
Term
word to describe air?
Definition
Mixture
Term
Earth's atmosphere is thought to have become enriched in which gas about 2.5 billion years ago?
Definition
gas from volcanic eruptions.
Term
Practically all clouds and storms occur in this layer of the atmosphere?
Definition
Troposphere
Term
Compare and contrast weather and climate.
Definition
weather is constantly changing and it refers to the state of the atmosphere at any given time and place.
Climate however, is based on observations of weather that have been collected over many years. climate helps describe a place or region.
Term
Why do seasonal changes occur?
Definition
Seasonal changes occur because earth's position relative to the sun continually changes as it travels along its orbit.
Term
How much of earths atmosphere is located below about 5.6 kilometers?
Definition
Half of the atmosphere.
Term
How do ozone molecules form in the stratosphere?
Definition
when a single atom of oxygen and a molecule of oxygen collide this collision must happen in the presence of a third, neutral molecule that acts as a catalyst.
Term
In which layers of the atmosphere does temperature increase with increasing hight?
Definition
Stratosphere.
Term
How are heat and temperature related?
Definition
Heat and temperature both have to do with energy in the air.
Term
List 3 major mechanisms of heat transfer in the atmosphere?
Definition
Conduction, convection, and radiation.
Term
How does convection affect the atmosphere?
Definition
much of the heat transfer that occurs in the atmosphere is carried on by convection. its the transfer of heat by mass movement or circulation within a substance.
Term
How does conduction affect the atmosphere?
Definition
conduction is the least important mechanism of heat transfer.
Term
How does radiation affect the atmosphere?
Definition
When radient energy is absorbed, it is converted to heat and causes a temperature increase.
Term
Describe what happens to solar radiation when it strikes an object?
Definition
Radiation will reflect off the light at the same intensity.
Term
Contrast reflection and scattering?
Definition
Reflection occurs when light bounces off an object. The reflected radiation has the same intensity as the incident radiation. in contrast, Scattering produces a large number of weaker rays that travel in different directions.
Term
what is a temperature control?
Definition
Any factor that causes temperature to vary from place to place and from time to time.
Term
How do the heating of land and water differ?
Definition
Land heats more rapidly and to higher temperatures then water. Land also cools more rapidly and to lower temperatures than water.
Term
Why do many clouds reflect a significant amount of sunlight back to space?
Definition
many clouds have a high albedo, and therefore reflect a significant portion of the sunlight that strikes them back to space.
Term
Why do coastal cities experience a moderation of temperature from water, while others do not?
Definition
winds do not carry the oceans influence onshore.
Term
list four specific controls of atmospheric temperatures?
