Temperature to which air must be cooled at constanct pressure to reach saturation: dew point
the gas formed by adding a third oxygen atom to an oxygenmolecule: ozone
heat that is stored in a substance: latent heat
an air mass's ability to resist rising: stability
the transfer of energy through space by electromagnetic waves: radiation
cloud droplets collide to form larger droplest in a process called: coalescence
the amount of energy the atomshpere absorbs depends in part on its level of: Carbon dioxide
You run over the hot sand, burns your feet what type of hear transfer is this: Conduction
Current short-term in variatins in the atmoshere are referred to as: Weather
Lines on a map that connect point of equal or constant values are: isopleths
Systems that lie between the poles and about 60 degrees latitude in bothe hemispheres: polar easterlies
Winds that flow between 30 degrees and 60 degrees north abd south latitude: prevailing westerlies
how do galaxies classified as E3 and E7 differ?: E3 galaxies have less elongated elliptical shapes
What are the characteristics of a glaxy that is classified as SBa?: a barred spiral glaxy with tightly wound arms and a large, bright nucleus
a record of weather data for a particular site at a particular time is using symbols is called: station model
High altitude clouds usually made of ice are: cirrus
the energy that drives the water cycle: sun
winds traveling at high speeds that encircle the Earth are called the: jet stream
examples of convection can be found in: -the inner layer of the earth magma
-the atmosphere
-the innerlayers of the sun
Which of the following plays an important role in convection?: warm material rises, while cooler more dense material sinks
The constant movement of water between the atmosphere and the Earth's surface is: the water cycle
polar and tropical regions maintain fairly constant temperatures because: the continual motion of air and water reallocates heat energy throughout the Earth
the exchange of heat or moisture with the surface over which an air mass travels is known as: air mass modification
When moist winds approach a mountain, they often drop rain as they rise over the mountain, and come down the other side of the mountain: cooler and drier
outermost layer of the atmosphere: exosphere
contains concentrated ozone: stratosphere
most weather occurs here: troposphere
cold dense air that displaces warm air, forcing the warm air up: cold front
narrow region separating any two air masses of different desities: front
advancing warm air that displaces cold air: warm front
A wave cyclone begins along this type of front: warm front
cold air mass that moves rapidly and overtakes a warm front: occluded front
two air masses that meet and do not advance: stationary front
an extended period of well below normal rain fall is a: drought

hurricanes get their energy from: warm ocean waters over 80 degrees
The Fujita scale measures: tornado damge and intensity
Which of the following heats most slowly: water
the energy needed to raise a given volume of a substance one degree Celsius is called: specific heat
It is December and the temperature is below freezing. A low pressure center is moving into the area. You can expect: cloudy weather with snow

The process in which the ocean floor returns to the earth's interior is called: subduction
sea floor spreading occurs at: mid-oceanic ridges
when two continental plates collide: both placctes push upward to form mountains
the force that moves the plates of the Earth: convection currents in magma
a fault where two plates slide past one another is called: transform boundary
the ring of fire: -is an area of high volcanic acitivity
-is found at the borders of the pacific plate
-is an area of high earth quake activity
Where can you expect the most violent earthquakes: transform boundaries
the earthquakes that are concentrated in the mid-west are caused by: the new madrid fault
volcanoes and earthquakes: -tend to occur near each other
-follow the pattern of the earth's tectonic plates
-can occur on plate boundaries in the middle of the ocean
which theory states that the Earth's crust and rigid upper mantle are divided into plates which move in different directions and rates: plate tectonics
most divergent boundaries are found: on the seafloor
Scientists rejected Wegener's hypothesis of continental drift because he: couldn't explain how or why the continents moved
When the Earth's magnetic field reverses: minerals containing iron turn in the lava which is cooling to form rocks
Crust is neither destroyed nor formed along which of the following boundaries: transform
The San Andreas Fault is located: In California
If you plotted the epicenters of all known earth quakes on a world map, the result would show: the margins of the earth's tectonic plates
a numerical scale of earth quake magnitude that takes into account the size of the fault rupture is the: moment magnitutde scale
the point within the Earth's crust where a fault moves is called the: epicenter
