How do red and blue light differ?
The wavelength of red light is longer. (E1)
Which gases are primarily responsible for the atmosphere greenhouse effect in Earth's atmosphere?
Water vapor and carbon dioxide (E1)
Much of the carbon dioxide found in earlier atmospheres is currently locked up in
Carbonate rocks (E1)
The most important reason why summers in the Southern Hemisphere are not warmer than summers
in the Northern Hemisphere is that
Over 80 percent of the Southern Hemisphere is covered with water (E1)
If Earth did not have an atmosphere, the sky would appear _______ during the day.
Black (E1)
Which atmospheric layer contains the most mixing and overturning of air?
Troposphere (E1)
On what date is the Sun the most intense in the Northern Hemisphere?
June 21 (E1)
Without the atmospheric greenhouse effect, the average surface temperature would be
Lower than at present (E1)
As ocean temperature increase, which greenhouse gas increases and enhances the atmospheric
greenhouse effect, thereby illustrating a positive feedback process?
water vapor (E1)
The blue color of the sky is due to _________.
selective scattering of visible light by air molecules. (E1)
The temperature of the tropopause
is much colder than the temperature at Earth's surface. (E1)
The Sun emits its greatest intensity of radiation in the
visible portion of the spectrum (E1)
Suppose yesterday morning you noticed ice crystals (frost) on the grass, yet the minimum
temperature reported in the newspaper was only 35 degrees F. The most likely reason for this
apparent discrepancy is that
temperature readings are taken in instrument shelters more than 5 feet above the ground. (E1)
, Ideal conditions for a strong radiation inversion are a
Clear, calm, dry, winter night (E1)
At which temperature would Earth be radiating energy at the greatest rate or intensity?
105 degrees F (E1)
What is released as sensible heat during the formation of clouds?
Latent Heat (E1)
Our seasons are caused by
the angle at which sunlight reaches Earth. (E1)
The temperature of a rising air parcel
always cools due to expansion. (E1)
The amount of heat energy required to bring about a change in temperature in a substance is called
the
Heat Capacity (E1)
A star much hotter than our Sun radiates more energy at _______.
Shorter wavelengths are appears bluer. (E1)
What determines the type (wavelength) and amount of radiation that an object emits?
Temperature (E1)
The unit of pressure most commonly found on a surface weather map is
millibars or hectopascals. (E1)
Although the polar regions radiate away more heat energy than they receive by insolation in the
course of a year, they are prevented from becoming progressively colder each year by the
circulation of heat by the atmosphere and oceans. (E1)
The most abundant greenhouse gas in Earth's current atmosphere is
Water Vapor (H2O). (E1)
Water vapor can best be described as a
Liquid. (E1)
Secondary rainbows occur when _________.
Two internal reflections of light occur in raindrops. (E1)
