ESC1000 Chapter 17 Quiz
When did oxygen levels begin to increase in the Earth's atmosphere?
During the Proterozoic.
If water boils at a temperature of 373, what scale is being used?
Kelvin
Where is atmospheric pressure the highest?
at sea level
A barometer measures
atmospheric pressure.
Based on the figure, what type of front is present in Texas?
cold
Clouds form because as the air rises it
cools and reaches its dew point.
The cloud labeled A in the diagram is an example of what kind of cloud?
cumulonimbus
Photochemical smog results when
exhaust from cars reacts with air and sunlight.
Radar reflectivity values indicated in red or orange are interpreted to represent
heavy rainfall.
Longwave radiation includes
microwaves.
Which type of cloud is most likely to produce precipitation?
nimbostratus
Observing the aurora borealis, you see shades of blue. What chemical element are you observing?
nitrogen
The two most abundant elements in the Earth's atmosphere today are
nitrogen and oxygen

Most aerosols found over the ocean are
salts and sulfates.
The type of precipitation that occurs when raindrops fall through a warm layer of air on top of a freezing layer, producing frozen pellets near the ground, is called
sleet.
In the image of the Earth's atmosphere with layers defined by temperature, which layer is labeled B?
stratosphere
The ozone hole is found in the
stratosphere.
The temperature of the Earth's troposphere decreases as the altitude increases because
the Earth's surface heats the troposphere from below.
If the Earth did not experience the greenhouse effect,
the temperature of the Earth would be much cooler.
In the image of the Earth's atmosphere with layers defined by temperature, which layer is labeled A?
troposphere
The Earth's first semi-permanent atmosphere consisted of abundant water vapor, carbon dioxide, nitrogen, ammonia, and traces of methane. These gases came from
volcanic outgassing.
Water in its gaseous form in the atmosphere is called
water vapor.
